I opted for just buying a nice lightwieght aluminum RIB (AB-UL9, 75 lbs), this project was going to take up too much time and by the time it was...
I built all of the windows from 1/4" polycarbonate. The forward opening window is supported by 3 Seadog SS hinges and two SS gas struts. It is...
Updating this thread with my latest design. It keeps the original boom in place but adds a much lighter cored composite sail cradle mounted from...
The original boom was designed with a track for track-mounted reefing blocks on the starboard side. These were not on the boat when I purchased...
The original boom mounts inside the pocket. This purpose of this design is twofold: 1) provide better sail catching ability and sail support than...
I agree, a closed section and open box would be relatively straightforward to build. Probably the easiest would be to shape the closed section in...
TANSL, I think you are right in that the best way to approach this is by just creating a closed section with non-structural wings forming an open...
This is very useful. Thank you for the force analysis. I think we all gained a better understanding of the forces on the boom by seeing this....
Thank you for better articulating my concerns around the bending formulae and section modulus. I think this is the concern I was trying to...
How would I go about calculating these shear and interlaminar stress in the section plane? I would like to know about these torsional forces too.
