Research on fatigue of fiberglass sailboat hulls (J/24's) - United States Naval Academy
There are a bunch of links here and it is quite an excellent page
that, in my opinion deserves it own posting. Roger Long are you the naval arch. who bought your boat from a fresh water lake, Erie or Michigan? I hope you enjoy this page...... http://web.usna.navy.mil/~phmiller/usna1.html Associate Prof. Paul H. Miller Naval Architecture and Ocean Engineering Department United States Naval Academy Some of the links are HTML some are PDF's and others are Power Point Presentations..... __________________________________________________ __________ http://web.usna.navy.mil/~phmiller/J...24fatigue.html This page briefly describes a project that looked at fatigue effects on marine fiberglass. The project's goal was to correlate (and improve where possible) standard test methods, theory and computer-aided analysis tools to give designers more confidence when developing specifications for marine composite components. __________________________________________________ ___________ New Navy 44 Midshipmen and TAD Ensign Projects Velocity Prediction Program Study Naval Architecture Senior Design Project Material Selection Study Impact panel video (Navy 44 vs. Navy 44) Impact panel video (Navy 44 vs. J/24) Full-scale impact video!

Yup, that's me.
Very interesting paper. I'm glad I found a 32 foot boat with a 3/4 inch thick hull. It's still probably stiffer than most boats built five years ago. The full length aluminum toe rail has to help as well. BTW, after a summer of sailing, I love the Endeavour 32. If anything happened to it, I would look for another one tomorrow. The quick helm response is a bit of a pain when I singlehand but I love it when I have a crew (which is most of the time). -- Roger Long "Mic" wrote in message ...
