kayak design

Kayak Design is the process of designing a kayak for a specific application (e.g. Touring kayaks, Fishing kayaks, etc.), and other parameters such as the user’s size, proficiency in paddling, the overall load capacity required from the kayak, speed, stability, etc.
Other kayak design factors are materials (e.g. Polyethylene resin, fiberglass, etc.), manufacturing technology (e.g. rotational molding, thermo forming, cold molding, etc.).

Kayak design is a term also used to refer to the kayak’s form (type), such as sit-in, sit-on-top (SOT), hybrid and twin-hull kayaks.

A snook almost too big for my measuring board – 1st place in the tournament

By Gary Rankel

Nature Coast Kayak Fishers

I just happened to catch my biggest snook in 12 years, this 35 incher that was almost too big for my measuring board. To top it off, I got her during our annual catch-photo-release kayak fishing tournament, leading to a first place finish for biggest fish, a nice trophy, a new fishing rod, and a $200 check.

Life is good.

BTW, another little known benefit of the Wavewalk, is its cockpit design which better supports a measuring board while photographing fish prior to release. This task really requires 3 hands, and is much more difficult to accomplish in mono-hull yaks where it’s harder to stand up or, otherwise, get farther away from the fish with a camera to capture it entirely on the board, while keeping it from jumping off, so judges can verify its length.

Maybe it will be possible to have a measuring device inscribed or attached to the platform of your new S-4 vessel, making it even easier to get this job done.

First images of S4 hull and assembled test unit

Today our molders ‘broke in’ the Teflon of the S4 mold.
They molded a few hulls from low grade material, and assembled a mock S4 to see that everything works well.
And it does: The mold works perfectly, the S4 parts fit together nicely, and everything is cool. We did it!  🙂

We’ll start shipping S4 orders next week.

Here are some first images of the assembled test unit – Note that the molders didn’t bother to apply the W logo to this test part, or trim it along the parting line and cockpit opening, because next week they’ll send it the grinder.

Note that when mounted on an actual S4 boat, the mounting plate will be attached to the rear end of the cockpit by means of two 3/8″ bolts.

First S4 twin-hull (test unit) sits in Wavewalk’s assembly area. The actual S4 product will feature a W logo on each side of the stand-up casting platfrom

View from a rear angle. The rear carry handles and mounting plate are visible, and the front saddle bracket can be perceived too, with a little effort.

Front view with the casting platform and front carry handles. The rear saddle bracket is visible, and so is the mounting plate.

Rear view with the rear carry handles, the mounting plate that fits perfectly inside the molded-in mount, and the front saddle bracket that’s barely visible.

Simple anchoring for Wavewalk fishing kayaks

By Gary Rankel

Nature Coast Kayak Fishers Club

 

A few years ago, not knowing any better, I submitted a short piece showing how to install an anchor trolley on my Wavewalk 500.
Having had 10 years experience and hundreds of fishing trips in my Wavewalk fishing machines, I’ve come up with a number of ideas to simplify rigging the W for fishing, one of which makes the anchor trolley idea obsolete.
While anchor trolleys are useful additions on mono hull yaks, the twin hull design of the W offers a much easier alternative.

All that is required are 2 holes drilled into the fore and aft cockpit rims (ignore the third middle hole in the photo used for another purpose), through which cords, knotted on each end, are attached.
Simply attach a plastic snap clip onto both the cord and anchor rope and “anchors away”. Deploy the anchor to the front or rear depending on which way the current is flowing. This is about as simple as it gets, with no banging of hardware on the W to spook fish.

This arrangement works with the W700 as well, however, the deck mount will prevent it from working on the front of the new S4.

Hope this helps Wavewalk users looking for a simple anchoring fix.

Wavewalk S4 mold completed

The S4 mold got coated with Teflon, and our mold makers are done with its final inspection.
It’s on the way to its new home at the production facility where our kayaks and boats are made.
Developing and producing such a large size cast aluminum tooling is a complicated and lengthy process, and it was carried out pretty much on schedule.
We are planning to produce the first S4 units next week.

 

The top part of the S4 mold. The golden-brown glossy material is the Teflon coat.

 

The purpose of coating the inside of a mold with Teflon is to prevent the Polyethylene from sticking to the mold after it’s cooled down.
If the Polyethylene sticks to the mold, the production team can have a hard time taking the molded boat out.
