You can go paddling in tandem in your W Kayak, and by tandem we mean two adults, providing none of you is a big person (see Wavewalk website for details). However, that doesn’t necessarily mean that you can go fishing in tandem, and again, by tandem we mean two adults onboard.
Although it may be possible we would hesitate to recommend it for the following reasons:
First, paddling requires less personal workspace than fishing does, especially if one paddler or both use single blade (canoe) paddles, which are shorter than double blade ones.
Second, paddling is a regular and repetitive action with little or no surprises. Even if you paddle in moving water (E.G. river, surf) you can assign strict roles to each of the paddlers, and by doing so increase your efficiency and minimize unpleasant surprises.
In comparison, kayak fishing can turn chaotic instantly if one of the crew needs to fight a big or strong fish. It’s important to remember that when two persons are onboard the W Kayak is less stable than when only one person is.
Third, fishing involves the use of hooks and other sharp objects. If both fishermen are experienced the risk is minimal, but if they are novices there is a risk that someone might be accidentally injured.
Fourth, fishing sometime requires a lot of additional gear, and with a second adult fisherman onboard the storage space in the W Kayak becomes considerably smaller.
As for fishing in a tandem composed of one adult and one child, it is a very rewarding experience that many W Kayak owners enjoy on a regular basis.
