Hello Zaphod. We are just completing purchase of LN41 #31 built by Hart/Hai O Yachts in 1983. The survey shows a solid but wet hull, and the history shows a two blister repairs. Long-term, I would love to be brought into the fold and establish communication with other Lord Nelson owners. Your comments suggest that you spoke with T. Chen designer. Awesome! So do you also think our boat is solid laminate without a core? Would love to hear from you if even just to hear some of your stories. /Matt Warren, 216.401.6813
