More aft...jbo_c wrote: ↑Sun Aug 01, 2021 9:05 am As seen on another thread, I’m considering taking over an incomplete GT23 project. That hull is not really what I was looking for originally, but it is tempting. So I have a few questions - mostly for Jacques, I guess.
1. The “houseboat” hull: According to the study plans, the difference is in the forward volume and the transoms are the same. So the houseboat hull is also what we’d refer to as a “planing hull”? Or maybe as a whole, the design is more semi-planing?
2. Along those same lines, Jacques notes that a 25hp would be perfect. That still confuses me if the hull is a planing hull. How is that? Is this statement true for both versions of the hull?
3. This one may be harder to answer. My intent was to have the cabin more aft. Since this is the ‘performance’ hull, I’m thinking my aft cabin would actually be the better way to do it anyway. Is that right? How do I make sure the weight distribution is “correct”? Looks like my I intended cabin will be lighter(smaller) than what’s on the plans, but probably not a lot as I really don’t have any plans to make it out of foam.
One of my biggest ‘concerns’ is that my intent has always been for very low power - 10hp or less. Don’t want to invest a lot of time and money in this only to wish I’d stuck with my original thoughts. (I know I’m the only one that can make that call.

Be careful, this is a generally incorrect concept.
Most boats with outboards need centers of mass aft of the midline, but an open bow, aft cabin boat may perform poorly. Ask the designer.
