[quote=sierracat][quote=bacho]Google some Nacra 18 square pics, should answer boom questions. Looks like most of the boats used one,[/quote]
Very early 18sq used a boom, and I believe later versions went boomless. It's difficult to figure things like this out when the Nacra models spanned many years, and were constantly evolving, especially since 18sq were a development class. I've looked at more 18sq photos on the internet than you can imagine - usually pictures of boats on the water from a distance and difficult to make out much detail, and most have a much more modern (square top) sail than what I have.
Anybody who has some good detail photos of boom setups on any Nacras, I'd love to see them. Like Wolfman says, I should probably sail it first as is before putting any money into further mods, but I can already tell the mainsheet angle and poor sail tension long the foot and elsewhere is going to bother me. I might go ahead and just make it a boom rig. The 20' stick of aluminum I bought for the beams (4" x 0.125) was only $100, so I'm guessing 6 or 8 ft of 2"x 1/8 or even 1/16th won't break the bank. Especially if kind folks have some fittings to send me! (thanks Wolfman).[/quote]
