I didn't see the brackets on the Gause web page?? I'm curious as to the design and flotation amount. I just measured my Hermco twin bracket to get the flotation. The sides and ends slope a little going up so I just averaged the area. The bottom is V shaped and parallel with the keel. The bracket v up to the point where it's rectangular came out to 4.12 cubic feet which would be 263lbs. The rectangular area is 50x30 inches which came out to 0.86 cubic feet per inch of depth which is 55lbs per inch of depth it goes into the water beyond the V bottom. So if the bracket were mounted up 3 inches from the keel, and if the waterline was normally 18 inches up from the keel, then 5.5 inches of the rectangular section woul dbe in the water and that would be 5.5 x 55 = 302lbs. So that's approximately 560lbs of flotation.....so probably 420+ after taking out the weight of the bracket. It's all approximate....
Anybody know the design CG for 23ft hull.
