What’s under your sit-on-top (SOT) kayak?

A kayak’s deck and cockpit are its most visible parts, and few people bother to look under a kayak, although there are some interesting things to discover there –

The kayak’s underside is its part that comes in contact with water, and as such its design affects the kayaks speed and directional stability. SOT kayaks used for fishing are notoriously sluggish, and they’re also known to track poorly.

This new article entitled The secrets of the SOT kayak’s underside talks about two characteristic features of SOT kayaks, which are scupper holes and longitudinal tunnels, it analyzes the effect these elements have on the kayak’s performance, and most interestingly, it explains the real reasons why these elements came into being and became standard in SOT kayaks.

Review of 2013 fishing kayak design trends

A meager harvest when kayak anglers are concerned, and plenty of reasons for a good laugh 😀

2013 hasn’t been much different from previous years as far as fishing kayaks are concerned. The kayak obesity trend keeps being the main one, and it drives kayaks to reach titanic proportions. For example, kayaks that are 35 inches wide and weigh 80 lbs are almost typical, and a kayak that’s over 40 inches wide is no longer viewed as an aberration despite the fact that paddling such a kayak is quite a challenge, and almost impossible to do for medium and long distances. Leviathan barge kayaks weighing around 120 lbs are still considered as kayaks (at least by some) although even a seasoned weight lifter might find it hard to car top one, and people who buy them have to buy a trailer to go with them, which is yet another way to defy the purpose of kayak fishing.
The reason behind the persistence of this trend is the poor stability that fishing kayaks offer to their users, albeit the fact that kayak manufacturers insist that the kayaks they offer are very stable, enough to allow for kayak fishing standing… Go tell this to all those disappointed anglers who purchased such kayaks and found out that reality is different from bogus reviews and staged YouTube movies  🙁

Fishing kayak hulls keep featuring all sorts of weird longitudinal channels and vertical dimples that work perfectly to create more drag and by that further impede the kayaker and make it harder for them to paddle. The infamous scupper holes that were introduced as means to prevent the deck from collapsing but have since been hyped as drainage holes keep conducting water in both directions, which means they also drive water up and onto the deck, and into the paddler’s area.

In the twilight zone, kayaks with integrated outriggers are still being offered although the concept has proved to be rather useless in practical terms. It seems like the failure of the kayak industry to present kayaks that actually work for stand up kayak fishing drives more people to try outriggers.

New designs still appear on the scene, and they make one wonder if kayak designers have any ability to learn from others’ mistakes.

Pedal driven kayaks are still being promoted as the panacea, although reality has disproved most of their manufacturer’s claims as far as practical usefulness is concerned.

Kayak storage keeps relying on hatches, which are often inaccessible to the user while they’re out there in their kayak, trying to fish from it. Such hatches have an annoying tendency to fail to be waterproof, and that’s bad news for your sandwiches!

When ergonomic design is concerned, manufacturers seem to realize that the kayaks they offer are really uncomfortable, so they keep trying to come up with new ideas for seats, although it’s the seat itself together with the L sitting position that cause the back pain and leg numbness problems that so many anglers experience.

Motorizing… well, oddly enough, some kayak manufacturers tell their clients they can outfit their kayaks with powerful outboard gas motors. Naturally, not too many people buy into this nonsensical notion. The most ridiculous case in this regard is a kayak manufacturer who offers his clients to attach their outboard gas engine directly to the kayak’s transom, which like the rest of that kayak is made from a thin, rotationally molded plastic wall… It is only appropriate to apply Hanlon’s razor to this case, and say “Never attribute to malice that which is adequately explained by stupidity.” 😀

And last but not least, fishing kayak manufacturers keep competing with each other by offering an increasing range of useless accessories, from cup holders to stand-up metal frames and stand-up ropes and straps… The latter being pure exercises in futility, at least from the user’s standpoint.

No wonder the Wavewalk 500 keeps being the most loved fishing kayak out there!

When a fishing kayak turns into something else…

Sometimes a design offers more than the eye meets. In this case, a patented fishing kayak offering unrivaled stability and comfort as well as unmatched storage space and dryness can turn into a self-motorized water skiing device by virtue of its small size, light weight, ease of use, and tracking capabilities.

Watch this video:

Just drive around, standing up, with no motorboat to tow you… And you don’t need to be an athletic youth to perform this trick and enjoy it.

The middle aged guy demonstrating the kayak in this video is 6 ft tall and weighs 200 lbs.

The basic model of this rotationally molded Polyethylene W kayak weighs 59 lbs. The 2 hp Honda outboard motor weighs 29 lbs, and the transom motor mount adds five more pounds to the total.
The driver controls the motor and steers the craft through the tiller handle, which is outfitted with an articulated (jointed) tiller extension allowing for effective steering even when the driver is standing up.
This little wonder fits on top of any car rack, and inside some medium and large size vehicles.
It’s easy to carry just by dragging in on the ground by a strap attached to its bow, as demonstrated towards the end of the video clip.

Is this an effective solution for offshore trips? It is, and a simple and effective cockpit cover would provide additional protection from spray.

This watercraft can be outfitted with detachable flotation modules that would keep it afloat in case of a capsize accident leading to much water getting inside.

The more traditional ways to look at this small boat are either as a motorized fishing kayak or a personal microskiff. The difference between the two viewpoints is related to whether you’re used to fish out of a kayak or from a motorboat.

Fishing Kayak With 2hp Outboard Motor – Offshore

Here’s a recently produced movie showing a W fishing kayak outfitted with a 2hp 4-cycle Honda outboard motor, at the beach.
In this configuration, this kayak is a car top motorboat, eliminating the need for a trailer. It can be dragged on the beach, as well as on dirt, rocks and grass, which in most cases eliminates the need for transportation wheels.
Passengers and gear can stay dry due to the high free board, in combination with the cockpit cover. The kayak seen here is outfitted with extra large flotation modules on both sides, so it it happens to capsize, it should keep floating, even with the outboard motor mounted on it.
launching this watercraft is easy from any location, due to the fact that it benefits from triple propulsion: motorized, paddling, and poling (with the W paddle).
This motorized fishing kayak can even take a second passenger on board, although they may occasionally get splashed, as the 2hp outboard drives the boat at a 7mph speed.
This unique, patented twin-hull watercraft offers enough stability without adding stabilizers to it, and the driver is seen standing up while driving it, even in the presence of mild waves.
Steering is easy and intuitive, through an articulated tiller extension. This is particularly effective with this Honda motor, because it is controlled through its tiller grip handle.

Kayak Design: The Difference Between Addressing a Problem, or Tackling It, and Solving It

Design isn’t just about aesthetics. It’s first and foremost about solving problems.
Yes, this is not a mistake – I wrote SOLVING problems, and not addressing problems, or ‘tackling’ problems, which are expressions that are commonly found in marketing hype for all kayak types, including fishing kayaks.

And that makes a fundamental difference, because when you tackle, or address a problem, it’s still there after you’re done – You may have created a design that emphasizes stability a little more, but its users will have to pay a price in reduced speed and worse tracking, and still not paddle a kayak that’s sufficiently stable…
But when you solve a problem, it’s gone: It’s no more a problem.
Similarly, you may ‘tackle’ the problem of kayak back pain (a.k.a. ‘Yak Back’), or ‘address’ this problem by various means ranging from stuffing more foam in the kayak’s seat, or gel, or replacing the stuffed seat by a beach seat, or stadium seat adapted to kayaks, and yet, the problem of poor ergonomics will still be there, and this is bound to make the kayaker’s life miserable.

These examples illustrate the issue called the ‘envelope’ of a boat concept. In this case, it’s the broad boat concept called ‘mono-hull kayak’, or ‘single hull kayak’, and the families of solutions found within its envelope are generally described as Sit-In Kayak (SIK), Sit-On-Top Kayak, and Hybrid Kayak.

Being an extreme concept by nature (small size, narrow beam for paddling, light weight for carrying, etc.) this concept is most restrictive, which is why the serious problems it presents can be addressed and tackled, but no solved.

Does it mean such major cannot be solved? Not necessarily, but in order to solve them, the designer has to work within another paradigm, or boat concept, and explore a range of solutions available within its envelope. In the case of kayaks, such alternative concept exists, and it is known as W Kayak.
