Comprehensive spar thread
Posted: Tue Jul 28, 2009 11:40 am
So it looks like at the very least im looking at new spreaders and boom, so given the amount of work involved and the fact i have to buy a new boom, i thought id solicit opinions of the best rig and or boom size as well as any goodies people would put on to update the rig on my A35. Alot of my questions on winches and sheet and halyard arrangements are answered by reading on sailnet articles and here, but the nuts and bolts of understanding Booms and masts seem to be harder to find. I've looked on harkens site and there catalog which has some wonderful information, but its unclear how it relates to older boats.
I saw the post on jdi (?) spreaders and will prolly have them made there. I went to there website and they look like a good resource. Im betting on the sails needing to be replaced so there really isnt any upside to keeping the same rig as far as the main is concern
Initially, i was thinking about replacing the boom and spreaders and adding a bowsprit (only to use for an A spinnaker, rather than a true cutter rig) and possibly switching over to a low aspect rig
so in a perfect world, what options would you put on the boom to update a more modern rig?
Bear in mind I really dont know much about the details, so i actually dont understand terms like club footed or loose footed on sails. I searched through questions and answers but didnt find a comprehensive thread on updated spars so I figured this might do for all us newbies to use as a resource.
My initial thoughts are to have jdi Build another 15 foot boom, with a sail track, which if i understand correctly will also involve a new gooseneck as well to replace the roller reefing setup. I would also like to add an outhaul, a one or two line reefing system that can be used from the cockpit, as well as a preventer or a boom vang. I think you'll only see a boom drop a guy once before you get one of these! As well, I was gonna stick with end boom sheeting. I was going to stay away from lazy jacks for now, but think about adding it later if i head for the coast at some point.
What are the merits of an internal vs external reefing arrangement? I was leaning heavily towards external on everything just for ease of maintenance and inspection, especially if something broke in a blow. What exaclty is the difference between a 1 versus 2 line reefing system? If i understand these correctly, you can simply head up a bit and reef from the cockpit right?
I looked at the garhuaer catalog, but dont know the proper ratios. Can somebody educate me on an easy reef system, and a line type vang, and end boom sheeting as far as the working ratios and what would be appropriate for my size boat. Its a Little unclear once you figure in the difference in modern vs older rig types with sail sizes being different. They dont really qualify as to whether this is a low or high aspect mainsail or mid versus end boom sheeting and if they do its usually mid boom and low aspect.
Would there be an advantage to lowering and or putting the boom higher and shortening the boom.
From reading on the B29 resto site I kind of understand what it does physics wise, and he certainly makes a good argument for it, but how would an older boat match up with a more modern Low aspect rig?
Greg nestor identifies this as tender to 25 to 30 degrees heel, but if that was reduced down to 20 or so while maintaining the drive with better windward ability that would be good.
ANy advice and or discussions of "in a perfect world" would be appreciated. Links are good too if this has been discussed elswehere.
Thanks
