I was intrigued by this post, so I found the product description and 2 things jumped out at me. First, J.C. Harris saying that "he will be shifting one of his hobbies" to "walking on water". More appropriately, though, that with a Creature Comfort seat and a 240 cm double-ended paddle, the Kaholo looks like a viable alternative to the Sea Island Sport sit-on-topfor some situations.
Back when the SIS came out, there were some who felt that it didn't fit the bill for a fishing SOT and were asking about putting a seat on the San O' and turning that into a SOT. Various reasons were given not to do that, most having to do with the hull shape and stability, if I recall correctly.
But now I wonder if the Kaholo might not actually work for that. It has 2 more inches beam than the SIS and a hull shape with what looks to have great initial stability. It doesn't, of course, have as much ultimate stability as the SIS with its sponsons and hull shape, but if it's stable enough to stand up on, it should be plenty stable for sitting on (at least in conditions where fishing would be fun) even without the balance control provided by standing up.
The hull shape also looks to have much more wetted area (drag) than the SIS, so it probably wouldn't be as fast, but at 20 lbs lighter it should accelerate like a sports car, compared to the SIS. Forward, that is. With that "rocket ship" stern (as Ted Brewer calls them), accelerating backwards could have you chiseling water.
The fineness of the bow and the fins should also make it track very well, as long as the seat is located so that the center of gravity is at the right spot. And with the almost non-existent sail area of the hull, and the reduced sail area of the sitting paddler, weather-cocking should be next to nothing.
With a few more bungees, tiedowns, etc., it should serve very well for holding fishing or snorkeling gear. Don't know how scuba gear would work out because of the weight.
So I just thought I'd throw these thoughts out to the gang to see if anyone else has noticed the possibility.
