Reply to: NACRA 5.5 uni - project boat, main beam damage

[quote=sierracat]Thanks Edchris177, and I got your PM, I'll be in touch. I'm starting to realize my current beams don't add up. I think perhaps they didn't come from/with these hulls, even if the intention was for them to fit when they were rebuilt. They are 8ft 5in long (is this spec for the 5.5?) and 4" OD, and appear to be 3/16 in thick. The front beam has the tramp track riveted on, as people have pointed out isn't normal. The studs coming out of the hull need corresponding holes in the beams. As I said, the rear beam has holes that don't line up in a way that makes sense, and the front beam it turns out doesn't have holes at all! The beams have a lot of weird holes and stains from previous fittings, as if they were set up on a different boat. The Nacra manual shows the traveller track running the full length of the rear beam. Mine has a stain in the beam where it looks like one used to run full length, but now finishes short, on the inside of each hull. I've learned earlier Nacras may have had these short bolt-on travelers, and later boats had a full length traveller that was extruded. More postings as I unravel the mysteries.<!-- editby --><em>Edited by sierracat on Oct 01, 2014 - 09:12 AM.</em><!-- end editby --> [/quote]
