Sorry, but just because it looks like a boat, it's not a boat. A boat is much more than two surfaces laid at any specified angle. Choose a proven...
I base my claim on experience from my own catamaran. The underside of the pod must be flat, not rounded as it is right now. The depth must be...
You just need to put a pipe aft of the step at the keel that leads down air. No extra pressure is needed. Crucial is the wave formation behind the...
philSweet Please show us your numbers, no guesses. Compare boats with the same total weight, load capacity and interior space JS
EcoSmart 100 10,0/9,4 x 2,5/2,1 Here shows an ongoing project that is an application of the principles presented earlier. This boat is...
It is not a question of size but of speed in relation to length and total weight. Seven knots would have been more appropriate. JS
You do compare two boats with different load capacity and interior space. What you are doing is a completely different topic than what is being...
Of course, I meant boats with the same length but different widths. In my compilation, the boats have the same weight, interior space and payload....
Will Gillmore Show us your calculations in the form of charts, no guesses or speculations. Remember that a wider boat weighs more than a narrower...
Will Gillmore Check: Three planing boats V-bottom or flat bottom? https://www.boatdesign.net/threads/v-bottom-or-flat-bottom.64594/page-2
Will Gilmore Payload is always included in my calculations. This is what I call total weight. JS
In addition to what has been said in the compilation, certain parameters that are related to speed also apply. This mainly applies to the area...
Check: EcoSmart, an efficient motorboat https://www.boatdesign.net/threads/ecosmart-an-efficient-motorboat.66733/ JS
A summary of the most important parameters for creating an efficient motorboat is presented here. This basic data applies to all sizes of...
Just my old sketch from 1969. JS
You can call this creation whatever you want. See more on: 10m LOA Electric Powered Trimaran for Flatwater...
When we tested our electric trimaran, we could see that we went slightly faster in headwind than with the wind. I can only explain it with WIG...
Attached file shows how Edmond Bruce tested very small models. JS
We've done it. Two boats were built with the same dimensions, weight, length and width. The difference was mainly in the shape of the transom...
Before you can get an adequate answer, more information is needed, preferably in the form of a line plan. JS
