Cap’n Larry Jarboe: The Boat That Does It All

Quite a few years ago, back in the mid-1970’s, I was fortunate to work as a mate then captain of a large passenger carrying boat that took people snorkeling on the shallow coral reefs of John Pennekamp State Park in Key Largo, Florida.

I promoted our business with the phrase “If you can swim, you can snorkel.” Twice a day, we hauled up to 61 passengers a trip on a wooden Harkers Island-built boat to witness the amazing coral reefs and tropical fish that are found right here in the United States.

Today, the State Park concession that I worked from has about 4 multi-passenger snorkel boats that have evolved from that one vessel.

Like snorkeling, there are many marine sports that have sprouted over my lifetime.

Obviously, canoes have been with us for many years. But, who figured out that you could sit on top of a kayak or stand up to paddle a fat surfboard? These are relatively recent innovations that have attracted a huge following.

Then, there are those Wave Runners. When I grew up in the Fifties, we never figured you could have a motorcycle that flew across the water.

All of those sports are fun for those of us who swim but owning all four: a canoe, kayak, paddle board and Wave Runner is expensive, space consuming, and a major maintenance hassle.

What if one vessel did all this, and more?

The Wavewalk catamaran style skiff is the stable and portable boat that literally, does it all. A visit to the company website at wavewalk.com will show you the W500 and W700 solo and tandem twin hull kayaks that are easy on your back because they are straddled like a Wave Runner. Fishermen are especially fond of the Wavewalk design because they are so easy to stand up in order to spot or cast to their prey.

These magic boats can be paddled with kayak or canoe paddles or outfitted for gas outboard or electric trolling motor or both! And, they are lightweight enough to carry on top of your car without a special carrying rack or trailer.

I discovered the Wavewalk design while I was searching the Internet for the perfect kayak to establish a retirement rental business in Key Largo. My first Wavewalk was purchased at retail price. That little W500 was so good that I used it in my commercial fishing business in the Chesapeake region to supply Blue Catfish fillets to Linda’s Cafe in downtown Lexington Park and the Victorian Candle Bed and Breakfast in historic Hollywood, Maryland.

At present, in addition to two commercial fishing work boats, I have a fleet of Wavewalk kayaks for weekend Wavewalk Adventures in the State Parks and National Sanctuaries that surround Key Largo.

And, I am fortunate to be the exclusive Wavewalk distributor for all of South Florida. Contact me if you are in the Chesapeake region and I can arrange for you to have your own Wavewalk kayak.

On a nearly daily basis, I motor my green W700 skiff through mangrove creeks or out in the ocean to make my own adventures exploring places that are almost impossible to reach by any other method of marine conveyance. This Wavewalk lifestyle is a most wonderful and unexpected retirement pastime that I am most happy to share.

So, if you are tired of being cold this winter and want an excuse to visit the Florida Keys, you have one (as if you really need an excuse to visit paradise).

A trip to my website at floridafishingkayaks.com. will provide all the info you need to schedule a free Wavewalk Wednesday demo of this vessel. Or, a weekend rental with included guide service might be a way to enjoy a complete kayak, canoe, stand-up paddle board package in a boat that “does it all.”

Who knows? You might drive home with one.

Welcome aboard.

Testing 15″ short (S) shaft outboard motor performance with Wavewalk kayaks and boats

This article summarizes the research that Captain Larry Jarboe, of Florida Fishing Kayaks and Boats in Key Largo, Florida did on this subject, and we are very grateful to him for this exceptional contribution.

Background –

 

Larry’s main goal in conducting this series of experiments that lasted for several weeks was to find the “sweet spot” for 15″ (S) outboards, namely a setup that would enable him to successfully outfit W500 and W700 boats with such motors, which are typically cheaper and easier to come by than 20″ (L) motors.
His secondary goal in running these extensive tests was to check the performance of Wavewalk’s TMM 700 HD motor mount, and see if we could improve it.

Larry is a passionate fisherman, mechanic, and seaman. He works as a commercial fisherman and fishing guide, and he is Wavewalk’s distributor in Southern Florida.
For the past fifty years, Larry has been involved in using, building, refurbishing and testing motors in various land and water vehicles, including electric racing cars, regular cars and trucks, a wide range of small watercraft, and big diesel engines in stern-drive commercial fishing boats, such as he still operates in Key Largo.

Means and Method –

 

In his tests Larry used five portable outboard gas motors that he had refurbished and tuned himself. Some of the motors had 15″ short shafts, and the others had 20″ long ones, and their horsepower rating ranged from 2 HP to 5 HP. He also tested a couple of electric trolling motors.

Larry conducted his experiments systematically – Being a handyman as well as a mechanic, he built a series of transom motors mounts that enabled him to mount outboard motors of both sizes in various places at the boats’ stern.
In his tests, he changed the height of the mounting plate, and/or its distance from the cockpit’s rear end.

Results –

 

There is no “sweet spot” for mounting a 15″ short (S) shaft motor on a Wavewalk, and any configuration involving the use of such size motor would inevitably result in sub-optimal performance compared to the use of a 20″ long (L) shaft outboard motor of the same power.

The main problems that Larry found with 15″ short (S) shaft outboard were the following:

Ventilation

 

Outboard manufacturers recommend mounting outboard motors with their anti ventilation plate (sometimes called “anti-cavitation” plate) immersed a couple of inches below the boat’s lowest point, which by definition is always immersed. This inevitably means that the anti ventilation plate is several inches below the surface. If the propeller rotates with its blades too close to the surface, it sucks air from the surface, and instead of rotating in water it rotates in a mixture of water and air bubbles. As a result, the propeller loses efficiency and power.

  1. At higher speed – Larry found that with 15″ short (S) motors, ventilation started to occur at about 5 mph, when the boat was transitioning from a displacement mode into a semi-planing mode, and its hulls were slightly raised, thus pulling the propeller upward and too close to the surface. The higher the speed the more extensive the ventilation and power loss. No ventilation occurs with 20″ long (L) shafts, even at speeds higher than 12 knots (13 mph), when the boat is in a full planing mode.
  2. When making sharp turns – Larry found that the 15″ short (S) motors’ propellers sucked air from the surface while he was making sharp turns. This happened since the boats tilted on their side, and the propellers got too close to the surface. In this case, ventilation resulted in loss of power as well as loss of control, to some extent, which made turning more difficult. Such problem did not occur with 20″ long (L) shaft motor, which performed flawlessly in sharp turns at high speed.

Splashing and discomfort

Splashing – In order to avoid ventilation, it is possible to mount 15″ short (S) shaft outboards at a lower level, with its propeller immersed more deeply. This can be done when a specially designed motor mount is placed several inches behind the cockpit’s rear end. However, at such position, the lower part of the motor mount’s vertical mounting plate is too low and too close to the surface of the water, and it will come in contact with the water. In such cases, the result is spray splashing over the motor’s head and into the cockpit’s rear end. No such problems occur with 20″ long (L) shaft outboard motors when mounted correctly on a standard Wavewalk motor mount.

Discomfort – When the 15″ short (S) outboard is mounted several inches behind the cockpit’s rear end, it is harder for the user to reach the motor and its controls (e.g. choke knob, starter grip), and it is harder for them to steer. This is not the case with 20″ long (L) motors that are mounted at the rear of the cockpit.

Bottom line

 

There is no “sweet spot” setup that allows for mounting a 15″ short (S) shaft outboard on a Wavewalk (500 or 700) without it incurring serious drop in performance. The way to motorize a Wavewalk is to follow the recommendations of outboard manufacturers about mounting their motors, as well as Wavewalk’s recommendations that fully coincide with them, namely to use only 20″ long (L) outboard motors with Wavewalk’s kayaks and boats.

 

A sweet spot, sort of…

 

When Larry checked 15″ short shaft, weak electric motors, he found that the ventilation problem at higher speed didn’t occur, because such motors lack the power to propel a kayak at speeds that are high enough to make it reach a semi-planing mode, or have the propeller suck in air from the surface. Knowing about such a sub-optimal performance envelope, the user already expects sub-optimal performance. This said, this rule is not ironclad, and ventilation may still occur in case the boat makes a sharp turn.even when it is propelled by such weak 15″ short electric motors, and while going at low speeds.

This is to say that Wavewalk recommends not to use short shaft motors even in the case of weak electric trolling motors.

In sum, the only propeller shaft size that we recommend for all types of motors is 20″ long (L)

Measuring an outboard motor’s propeller shaft length

Some of our clients who already own an old outboard motor, and others who contemplate buying a used one, ask us how to measure the length of an outboard motor’s propeller shaft, in order to know for sure that the motor indeed complies with the 20″ long (L) standard that Wavewalk requires.
This is an important question, because Wavewalk kayaks and boats work well only with outboard motors that comply with the 20″ long (L) standard set by outboard motor manufacturers, and our company strongly recommends not to use short shaft (S) standard motors.

Here is the full answer:
For this matter, the propeller shaft length is measured from the inner top side of the motor’s mounting bracket to the horizontal anti-ventilation plate that’s above the propeller.

Note that sometimes the anti-ventilation plate is called anti cavitation plate, although this is an incorrect term.

In many cases, this distance between the inner side of the motor’s mounting bracket and its anti ventilation plate can be slightly bigger than 20 inches, and if this is the case, it’s a good thing.

If the distance you measured is under 20″, it inevitably means that the motor does not comply with the 20″ (L) standard.
In fact, most outboard propeller shafts are slightly longer than their stated standard. For example, the length of a 2.3 HP Honda L is 22.5″, and the length of this motor’s short (S) version is 16.5″. Similarly, the length of a short-shaft (S) 4 HP, 5HP and 6 HP Tohatsu is 17.1″.

But don’t fool yourself –  16″, 17″ and 18″ is not 20″, and it’s still a short-shaft (S) outboard, and it won’t serve your purpose.

Why is this so important?

The reason the outboard’s propeller shaft’s length is so important is that it determines both the propeller’s immersion below the surface, which is critical to its proper functioning, and the distance between the propeller’s highest point and the boat’s lowest point, which is critical for trouble-free and effective operation of the boat.

Please avoid using short shaft (S) outboard motors with your Wavewalk 500, Wavewalk 700, and Wavewalk Series 4.

 

Wavewalk® Series 4

High Performance Portable Boat – Skiff, Paddle Craft

This is Wavewalk’s 4th boat series since 2004, following the 300 (Mark I and II), 500, and 700 series.
Like all other Wavewalk® products, this boat is 100% Made in USA.

The S4 delivers the highest performance in the field of small boats and skiffs, even before you’ve reached the water, starting from the fact that at 98 lbs it doesn’t require a trailer for transportation, and it’s easily portable even on rough terrain.
Its patented twin-hull design delivers more stability than any small boat out there, including much wider and heavier ones.  This allows for driving in fast currents and in choppy water.
In addition, being a true catamaran makes this boat track better than other boats.
The S4’s extra large cockpit (8′ long x 38″ wide) offers ample room for two anglers or hunters and their gear, or for up to three adult passengers – a total of up to 680 lbs.
The S4 features a long saddle seat similar to the saddle of other high performance vehicles, which offers maximal balancing capability as well as full comfort for going in choppy water and for long trips.
The S4 features a stand up casting platform at its bow, such as can be found in a typical skiff.
The cockpit’s slanted sides allow passengers to paddle with more ease and better control than what canoes and tandem fishing kayaks may offer them.
The S4 has an extremely shallow draft, and this fact in combination with its portability, load capacity and high performance as a paddle craft makes it the most practical solution for shallow water fishing.

Benefits

Best Stability in Small Boats

  • Initial (Primary) Stability: The S4 is more stable than any kayak, canoe, Jon boat and small skiff, including Wavewalk’s W700.  A 200 lbs person standing with both feet in one of the S4 hulls will make it draft barely 1″ lower than it would if that person stood with one foot in each hull – hardly a noticeable difference.
  • Secondary Stability and Balancing Capability: The unique combination of a saddle seat (such as ATVs, PWC and snowmobiles feature) with high-volume twin hulls enables the passengers to balance themselves easily, intuitively, and more effectively than in any other boat, including kayaks, canoes, Jon boats, dinghies, skiffs, and personal watercraft (PWC / ‘jet-ski’).

The S4 is unrivaled in Stability terms.

Best Boat Ergonomics

The 15″ high saddle featuring in the S4 is similar to the saddle featuring in other high performance land and water vehicles, such as All-Terrain Vehicles (ATV), Personal Watercraft (PWC / ‘jet-ski’), and Snowmobiles, as well as certain Rigid-Inflatable Boats (RIB) designed for high speed motorizing offshore.
Passengers riding this saddle can travel for long hours, including in choppy water, without suffering from back pain or fatigue. This is due to the fact that while seated in the Riding position, with a leg on each side of the saddle, the passenger’s legs support them in the most effective way, and no horizontal pressure from a backrest is being applied on their lower back.
In addition, the S4 passengers can stand up any time they want, and keep driving and paddling while standing up. They can even lay down with their back on the saddle, and relax. Switching between positions assures that no extreme fatigue or tension would build up in any part of the passenger’s body.

Easy Transportation and Full Portability

The S4 weighs 98 lbs without a motor attached to it. This means that it does not require a trailer for transportation, since it can be car-topped. The S4 can be dragged or carried over rough terrain, and launched practically anywhere, whether it’s a rocky beach, shallow water, and other difficult spots that are not accessible to other boats.

Mobility and Range of Travel

The S4 can go anywhere, thanks to a number of special features –
No other boat offers such a combination of shallow draft and total multi-modal propulsion, namely the ability to keep going in an effective paddling and poling mode even if the water is too shallow and/or infested with weeds to allow for motorizing.
No other small boat works so well both on flat water and in the chop.

On Board Storage

The space available for dry storage on board the S4 is equivalent to the storage offered by a good size Jon-boat, or a regular skiff.

S4 vs. W700

  • W700 advantages over the S4:  Solo kayaking, solo fishing, tandem kayaking, solo canoeing, tandem canoeing, portability.
  • S4 advantages over the W700: Motorizing, tandem motorizing, tandem fishing, stability, offshore trips, load capacity.
  • Shallow water – The S4 drafts less than the W700, and it features a skiff stand up casting platform, but the W700 paddles better, generally.
  • Offshore – Being more of a boat than the W700, the S4 offers a clear advantage in the chop.

 

Choosing an outboard motor for your Wavewalk® 700 skiff

This article is an attempt to answer some questions that Wavewalk skiff owners ask in the process of choosing an outboard motor for it –

Short shaft or long shaft?

We definitely recommend using outboards that feature a long (20″) propeller shaft, and for multiple reasons, which are discussed in this article entitled Outboard motor propeller shaft length for Wavewalk fishing kayaks and boats »
We recommend not to be tempted by the availability and lower price of 15″ short shaft outboard motors, because such motors don’t fit the W700, and using one would never produce optimal results, even for a highly skilled individual with a lot of experience in boat outfitting.

Here is a list of long (L) 20″ shaft outboard motors currently available in the 2 to 6 horsepower range, and their HP rating:

  • Honda 2.3 HP (air cooled), 5 HP
  • Suzuki 6 HP
  • Evinrude 6 HP
  • Tohatsu 3.5 HP, 4 HP, 5 HP, 6 HP
  • Yamaha 2.5 HP, 4 HP, 6 HP
  • Mercury 3.5 HP, 4 HP, 5 HP, 6 HP
  • Mariner 3.5 HP, 4 HP, 5 HP, 6 HP

Recommended reading –

Air cooled or water cooled?

Water cooled motors are quieter but heavier than comparable air cooled motors.
The only motor featuring on the above list that’s not water cooled is the Honda 2.3 HP. It is very lightweight, and works very well, but being air cooled makes it considerably noisier.

Note: Outboard motor manufacturers recommend flushing the motor’s cooling system with fresh water after every trip in saltwater. It’s possible to flush an outboard with a garden hose outfitted with a special adapter.

4-Cycle or 2-Cycle engine?

Nearly all new small motors on the market are 4-Cycle (4-stroke) and not 2-Cycle (2-stroke).
The advantage of the 4-Cycle system is twofold –

  1. The motor runs on regular fuel, and there is no need to mix it with oil.
  2. A 4-Cycle motor is cleaner, namely it emits far less stinky fumes than 2-cycle motors do.

Some experts argue that for the same displacement of its combustion chamber (cc, volume, size), a 2-Cycle engine in more powerful than 4-Cycle one, but we think that convenience and fresh air are more important.

electric or gas?

Many Wavewalk owners outfit their W500 and W700 with electric motors in the 30 to 50 lbs thrust range, and some go as far as 70 lbs thrust. They use their electric kayaks and skiffs for assisted paddling, recreation, touring, trolling, fishing, snorkeling, etc., but we prefer not to include electric motors in our list of “real” outboard motors for two reasons, which are:

  1. Power – Although some small electric motors are offered as “outboard motors”, just looking at their basic, objective power rating makes us think that they are too weak. Kilowatts to Horsepower conversion: 1 KW = 1.34 HP, and 1 HP = 0.745 KW. Consequently, an electric motor can work well on flat water and at a moderate speed, but not necessarily in adverse conditions, namely strong current, strong wind, etc.
  2. Range of travel – A gallon (3.8 liter) of fuel costs a few dollars, and it’s enough for a typical small outboard motor to run for 4 hours at a high RPM, or an entire day at a lower RPM. You can refuel a small outboard’s built-in fuel tank when you’re on board your Wavewalk®. You can take several gallons of fuel with you on a long camping trip, and you can buy more fuel almost everywhere, while recharging an electric motor’s battery can take half a day. Therefore, gas outboard motors offer a reliable and convenient solution whose price / performance ratio is unbeatable by any electric motor available today.

Weight

All small outboard motors listed above are considered to be Portable. However, between the 29 lbs of the 2.3 HP Honda and the 59 lbs of the 6 HP motors there is a considerable difference, if you need to carry the motor by hand over a distance.

The shallow water position

Most of the small outboard motors listed here offer to lock their propeller shaft in an intermediary position between the vertical (down) and horizontal (up) positions. In this intermediary, slanted position, the propeller drafts less than in the vertical position, and this allows for driving the boat at a moderate speed in very shallow (‘skinny’) water. Therefore, if you’re looking to fish in skinny water, we recommend that you look for this feature.

gear shift lever

Most outboard motors on our list feature a gear shift level, and this is a good thing, because the alternative is a centrifugal clutch that lacks an absolute neutral position. The absence of a full neutral gear can make starting the motor a little tricky, if you’re a beginner.
Our preference goes to the outboard motors that feature the gear shift lever at the front, rather than on their side. The frontal position makes it easier for the driver to access the lever whether the motors points left or right, and even if the driver is facing forward.

built-in fuel tank

All the above listed outboard motors come with a built-in (integrated) fuel tank, and this is a convenient feature considering the alternative is to have a fuel line run from a separate tank to the engine. When you operate such a small craft as a Wavewalk, simplicity becomes increasingly important.

propeller

The propellers that come standard with these outboard motors fit Wavewalk’s kayaks and portable skiffs. Typically, these motors propel much heavier boats, which is why the propeller’s diameter and pitch which determine output in terms of speed and torque are of no real consequence to the owner of a Wavewalk under normal conditions.

price and brand

All the brands listed above are known to produce quality motors, and in fact some of them produce motors for others. For example, Mercury is a Tohatsu brand. This is to say that we see no reason to pay more for a particular name brand, and we recommend to consider only the motor’s technical attributes, and its price.

HP rating – can i overpower my skiff?

6 HP is the absolute maximum for which the W700 is rated, and this is only for its RIB model. Overpowering your Wavewalk can be hazardous, and if you use the wrong motor mount you’d be calling for trouble. This said, if you happen to own a 20″ shaft 5 HP motor and your W700 is rated for a 4.5 HP motor, you can keep your motor, and you won’t necessarily have to get a new one. Similarly, if your W700 is rated for up to 4.5 HP and you found a nice 4 HP that you like, you’d be fine with it.

motor mount

If you choose to make a DIY mount for an electric trolling motor, chances are that you’ll succeed, since these motors are so weak that they’re not likely to cause trouble. But this is not the case with the gas outboard motors in the range that features on the above list.
There are several issues to overcome with motor mounts, and the motor’s weight is the least of them. The main problem is that operating at the end of a 20″ lever, the motor’s propeller generates a great amount of torque, especially at high speed, in rough water and when making sharp turns at high speed. This torque can twist and crack a 4×2 timber, and pull out nails and screws from their place. After having seen motor mounts get broken by outboard motors ranging from 6 to 3.5 HP that were mounted on them, we strongly recommend not to build a DIY motor mount for these motors, and to use only the motor mounts that Wavewalk recommends.

alternator

Some of the more powerful outboard motors listed here can be outfitted with an alternator and an AC to DC converter. Note that such accessories cost hundreds of dollars.
The electric current produced by this system can be used to power lights on board, or to charge a trolling motor’s battery. Such setups are common in bigger boats (e.g. bass boats) that feature much more powerful motors. Although some Wavewalk owners have outfitted their W700 with two motors (a powerful one for driving and a small one for trolling), we don’t know of anyone who’s outfitted their outboard motor with an electric current generation system.

Why an outboard motor?

Skiffs, Jon boats and other small boats sometime come with other motors, among which are air drives or air motors (large diameter propellers) for running marshes and flats, jet drives (similar to personal watercraft, a.k.a. jet-ski), long shaft mud motors for going in shallow water and over obstacles, and outboard motors that run on propane.

While each of these motors offers certain special advantages, and we’d love to see the W700 outfitted with any of them, as well as with other propulsion systems ranging from sails to oars, and even pedal drives… we think the common small outboards such as we listed here offer the optimal mix of price, performance, reliability, versatility, ease of use, and ease of maintenance – Just think how common are boat dealerships and repair shops that service these motors… And if you know how to use your outboard motor and you take care of it, it’s truly a wonderful thing that you’d enjoy for years, and possibly even decades.
