I don't do resin infusion or use CSM but ... 41% fiber content for UD 32% fiber content for BD work well for me as design estimates. They...
LVLs are made like plywood in large presses. Potlach Lumber will custom make plywood/LVLs upto 50' or so in length. I guess one could get...
no. no.
I expect that there are lots of issues that are being ignored here. We have a core and a couple faces. The usual loads include distributed...
bjl_sailor --- Let your work cure for a week or so. Then bang it hard with a big hammer several times all over. This procedure may not find...
Stephen Ditmore --- The 1.34 constant actually depends on hull length and shape. The values of .87 and 1.0 for the boats you mention are pretty...
It may be easier to use a better weave than to worry about the best ratio. Unidirectional cloth will be about 60% fiber (weight). Satin weave...
Thunderhead --- I expect you are correct. Most sail boat people are a bit laid back. Many are inconsiderate to the extent you say. I am...
"Most people who tries to save weight" But then most people are not engineers or even good builders and you must be both to save weight. It...
James --- you wrote: "Im assuming the price will reflect quality, most times." Price is not the correct measure. You might want...
Kayaks get full of water. You really don't want a boat that sinks.

Viscosity, curing temp, pot life. If you purchase products intended for amature boat builders ... The differences of importance will be in...
winap --- I would require 100% down payment. Once you supply that, I will get a crew together.
Perhaps you could use existing plans. I don't understand your reasons for a 20' boat, but you can scale up an existing 17' boat. 200# is too...
It seems that we and you are confusing 2 goals: 1) proper scantliings and 2) a proper design You appear to want to test a design. If so...
First, you decide how loads will scale. They scale differently for racing craft, pleasure craft, and cargo craft. Second, you design scantlings...
plastic chicken wire/snow fencing core glass/resin faces Not worth my time to do the engineering, but if it bonds well it should be ok.
If it is a race, swimming (towing a small boat) might be the best option.
The Wall Street Journal had an interesting article a couple weeks ago. An engineer started designing and building a 55' boat when he was in his...
