My aerospace company did work like this before I got there. Think 1970's.
They were trying to make thicker aluminum pieces (and other metals) in...
But that one will not go backward as well as forward.
How can you compare them?
But I still agree with your evaluation.
Can you describe the goals and requirements of your project?
I think the various navys around the world have shown what billions of dollars of...
I don't know why there are so many negative comments, the Movie "Waterworld" showed it can already be done.
SEEMED to work just fine.
Have you ever built a stitch and glue boat?
What is causing you problems starting?
Build something, then I'll dismiss your work just as easily as you do someone who actually designed, built and sold useful boats.
Does your gut...
Did you see the microbootlegger solo?
Might be about those numbers.
Actually its 14' x 26".
I don't know what qualifies as "high" block number,...
If you think about one, it is a little short for a double for normal sized people, but especially anyone tall.
The displacement claimed is 450# so...
It is interesting that in Japan it is common and not expensive to ship luggage between cities so you don't have to take it on the bullet train.

Coat the inside of the beam, unless you want it to rot and give you a chance to change the design...

This eliminates all the above discussion.
Saw it from the man who built Meade Gougeon's Elder Care...
Dave is a real expert, rather than us with just opinions.
The best help you have seen yet.
Developable hulls are a design compromise due to material manufacturing cost and design capability constraints.
The goal should be 3D fully...
+1 for checking the actual total impact on enviornment.
But, all the interest will lead to new ideas in how to iplement electric power.
As your picture shows, the forestay loads pull up, causing compression on the crossbeam.
What happens if the crossbeam crushes from those...
My mistake, its obvious when I looked better.
OK, I take back most of the nasty comment I made.
But does it support the forestay?
Anyone who tells you the rear crossbeam in not critical structure is looking to get you killed.
If you believe them then just cut it off at...
Paper is not like fabric or many other plastics.
Fabric certainly can bend in two directions at once.
Have you ever even seen a SOF in...
