The reason for the response is that Yoav is attempting to market his W boat as a "safer" alternative to a kayak and as offering the same level of performance, which is absolute BS on both counts. If one is a kayaker, the differences are quite obvious, as are the limitations to his design. However, all that may not be germaine to this discussion, since the intent is to solicit builders. If the design appeals to you, by all means build one. |

BTW, if you want to read something funny, check out all the pseudo-science, incorrect assumptions and misleading comparisons in his "speed" section. Amoung other things, he assumes that all kayaks need rudders and compares his boat to 13' recreational kayaks, which are known to be slow. If he compared it to a 17' sea kayak (a more typical length) without a rudder, his boat would not fare well. |

If he compared it to a 17' sea kayak (a more typical length) without a rudder, his boat would not fare well. I usually am not too critical of marketing messages. Otherwise, a trip to the grocery store would prove to put me into an impossible ethical dilemma: How can I choose the right soap when they all are "better", "fresher" and "improved"? On speed comparisons, the W Boat is less than 13' long, so the "speed" comparisons make sense. I wouldn't compare a boat 70% longer (there's that whole "theoretical hull speed" issue). Designers are usually very proud of thier designs, and tend to think they are better than other people's designs. I think that's appropriate; I wouldn't want to buy a design from someone who thinks his is inferior. Discussion of why they are right or wrong is appropriate also, but I'm not sure the ad hominem attacks bring more light to the issue. - - - http://www.messing-about.com Resources for the Boat Builder, Renovator and Small Boat Skipper |

Misleading people by telling them that the W boat is a better performer than a sea kayak, then comparing to recreational "tubs" is simply wrong. If he wants to bill it as better than recreational kayaks, there may be something to that claim, but it's not a substitute for a true sea kayak. |

If the design appeals to you, by all means build one. OK, I think I get you now. I think it looks like it would compare favorably to a poly sit-on-top kayak, but I suspect you're thinking of a traditional kayak, with a spray skirt, etc. I can't say how it would compare from experience, since I haven't tried either one, but you might be right that a traditional kayak has performance advantages. As to safety, I don't know which would be safer; an experience kayaker who has trained to roll himself back upright might be safer than a weekend warrior trying to get back into an open design like the W-boat. I have some experience with poly "sit on top" kayaks. The W boat design would probably have more initial stability than the sit-on-tops. He has a lot of pictures of people using it to fish from, and it looks like it makes sense for that kind of application. The sit-on-tops have a lot of wetted surface, so if the W boat does reduce that for the same load, then paddling would be easier. In any case, someone like Ookie who wants to experiment with the type of design can get some free advice in building one. - - - http://www.messing-about.com Resources for the Boat Builder, Renovator and Small Boat Skipper |

If the design appeals to you, by all means build one. OK, I think I get you now. I think it looks like it would compare favorably to a poly sit-on-top kayak, but I suspect you're thinking of a traditional kayak, with a spray skirt, etc. Precisely. I can't say how it would compare from experience, since I haven't tried either one, but you might be right that a traditional kayak has performance advantages. Trust me, it does. As to safety, I don't know which would be safer; an experience kayaker who has trained to roll himself back upright might be safer than a weekend warrior trying to get back into an open design like the W-boat. I would suggest the former, but I'm biased because I fit into that category. I've also seen exactly how quickly inexperienced/unprpared kayakers and other boaters can get into serious trouble. The claims being made for the W Boat make it seem like it's absolutely safe, which any experienced boat knows is absolutely untrue. Such claims could lure someone into getting hurt. I have some experience with poly "sit on top" kayaks. The W boat design would probably have more initial stability than the sit-on-tops. Definitely. He has a lot of pictures of people using it to fish from, and it looks like it makes sense for that kind of application. The sit-on-tops have a lot of wetted surface, so if the W boat does reduce that for the same load, then paddling would be easier. Agreed. In any case, someone like Ookie who wants to experiment with the type of design can get some free advice in building one. Sure. If it suits your needs, build one. Just don't think that it's a substitute for a kayak. It's simply too different and it has some serious limitations. |

The claims I have seen stats reported for injuries in watercraft, with the measurement being used stated as "deaths or injuries per mile" (or some measure similar to that). Kayaks and canoes came out as the most dangerous. Anybody ... and I mean anybody ... can rent a blow molded polyurethane kayak in our local waters and paddle around for an hour or two. They generally can't get back on them after falling off, so they use the kayak as a kickboard to get to someplace where they can get back on top of it. I suspect that type of person would be in a very dangerous situation in a traditional, sit inside kayak with a spray skirt. I asked Yoav about getting back onto a W Boat, and he said it might be a bit easier, but its still an issue (children can come up between the sponsons and, if they have the body strength, pull themselves up. Adults find it easier to grip the W Boat, but just like any other blow molded kayak, its easy to push it away from you when you're trying to get back up on it).

Just don't think that it's a substitute for a kayak. It's simply too different and it has some serious limitations. Well, I'm actually thinking of something a little different. I'd like to see if the W Boat design would lend itself to a low power runabout type of thing ... a two-seater with a small outboard ... 5 hp? ... that would get up to 7 - 10 knots. If it remains stable with the 40# on the stern, then it might be a fun little boat. - - - http://www.messing-about.com Resources for the Boat Builder, Renovator and Small Boat Skipper |

The claims I have seen stats reported for injuries in watercraft, with the measurement being used stated as "deaths or injuries per mile" (or some measure similar to that). Kayaks and canoes came out as the most dangerous. The stats are somewhat misleading, as on average there are only ~12 paddler deaths per year, nationwide. While it's true that the percentage is higher based on time, miles, number of boaters or whatever, the actual number of deaths is a tiny fraction of that of other boater groups. Interestingly, the paddlers most likely to die are fishermen in canoes, due primarily to a general lack of PFD use and the likelihood of alcohol being involved. Whitewater paddlers come next and sea kayakers are a distant third. Anybody ... and I mean anybody ... can rent a blow molded polyurethane kayak in our local waters and paddle around for an hour or two. They generally can't get back on them after falling off, so they use the kayak as a kickboard to get to someplace where they can get back on top of it. I suspect that type of person would be in a very dangerous situation in a traditional, sit inside kayak with a spray skirt. That type of person is in a very dangerous situation any time they're in more than a few feet of water more than a few feet from shore, particularly if the water is cold. The problem is that they don't realize the danger they're in. I see clueless people out on the water all the time. The fact that there isn't an enormous number of deaths per year is a testament to the seaworthiness of kayaks and just plain dumb luck. I asked Yoav about getting back onto a W Boat, and he said it might be a bit easier, but its still an issue (children can come up between the sponsons and, if they have the body strength, pull themselves up. Adults find it easier to grip the W Boat, but just like any other blow molded kayak, its easy to push it away from you when you're trying to get back up on it). The extra height of the W Boat does seem like it would make it more difficult to get back on. With sit-in or sit-on-top kayaks, it's really a matter or knowing the proper techniques for self-rescue. It's not difficult, but you need to know how and practice it BEFORE you get into that situation. In any case, someone like Ookie who wants to experiment with the type of design can get some free advice in building one. Sure. If it suits your needs, build one.

Yep, you're right ... they have been made before, but I haven't found plans for any. And this does give me a chance to work out plans myself with advice from someone who has toyed with the concept quite a bit. - - - http://www.messing-about.com Resources for the Boat Builder, Renovator and Small Boat Skipper |
