Still really paranoid about over and/or under building the framework. So, how bad would the cost be to have a design done by one of you pro's?...
http://www.boatingmag.com/all-aboard-boats-whats-deal-deadrise That about sums up everything I've read about the deadrise angle. Just not sure in...
Kohler's Eco 75 is very similar as far as bottom hull shape goes. http://duckworksbbs.com/plans/kohler/eco75p/Sampledrawing.PDF His deadrise...
Nope, that formulae is only for monhull. Still looking for proper formulae for multi so I can redo the calculations. Hull speed for the whole...
it helps, tyvm. So with the max hp at 70 it wasn't looking good. Change the back end design a little puts me at 110 max hp....
So i found " Centerline length times transom width times 2 minus 90. thats' in feet (such as 14.2 feet) transom width is the maximum width...
Ike: If applying the max rated power to a multihull you would just add the 2 transom widths together?
If I had the cash and wanted to get an existing design, the Skootas would be in the top 3 easy. I am mainly wanting to build something I haven't...
Ok, Ive been a bit paranoid that I had made some grave newb hull shape mistake. So assuming this shape isn't going to kill anyone, would this...
i was mainly just thinking the shallow v at the bow area might push the water like a plow rather than cutting through. So if i steepened the angle...
Manfred's responses on the 6m low power thread about kohler were the ones that got me thinking about it. I used to build and fly stick built rc...
I haven't done the back 7 ft yet. So i haven't done any. In case I have the terms mixed up, I am referring to tapering the bottom up towards the...
More pics I tried to get the camera in spots where you can see some of the angles better. Sorry it took a few days, it was the first chance I had...
So to get into specifics.... I added a v to what was originally a flat thinking it would grab some of the river's current and help keep the boat...
I was initially confused by this but i just reread my op. It was meant to say "something more than dual 10-15 hp" rather than "planing with 10-15...
Dave: I wasn't meaning to have a planing hull. I just goofed that way. So I was wondering if the larger motors were feasible for the structure...
So maybe this doesn't quite apply on boats, but from my construction experience I would think that you wouldn't want it to actually be level...
Dave: I had read that the usual method for figure total max load on a cat was to look at the load of one hull. This was for a sailing cat though...
Okay, I goofed slightly somewhere in the first calculations. Ive redone them and attached a pic of the calculations in case Im still messing it...
Messabout: for the methods, i thought about the stitch and glue and if it was a canoe or kayak I think i could have figured out the cuts needed to...
