Ok all you camberspar fan, time to revive the old thread. I just broke my camberspar. I just got a new sail and was wing on wing with the camberspar poled out to starboard and the wind 15 gusting 20 (true) 30-40 degrees off my starboard quarter. I was moving along quite nicely averaging 8 knots surfing the 2-4 footers (also coming from 30-40 degrees off the starboard quarter) in 10 knot
bursts. Wind was picking up a bit and got hit by an unusually large wave, maybe 7 feet + when we had been seeing nothing over 4. It was also unusually steep so suddenly I was looking down at the camberspar and the boat tried to turn to windward. The boat suddenly turned hard to starboard I looked up I saw that the camberspar was bending. I think the folding of the camberspar dumped the wind and of course as the main came around square to the wind without the jib forces to counterbalance it we turned about 50 degrees even though I had thrown the rudder
hard to port. This of course was a brand new sail that only had 2 days of use on it. It took me 30 seconds or so to get the boat turned so we could corral the sail and take it down. In the meantime the sail was completely out of control and the camberspar eventually snapped in two and one end ripped right through the pocket on the sail. I'm still trying to figure out what happened as I've had the sail up in much stronger winds and never had an issue. Of course that was with the old sail, not the new one. I would have thought the turn to starboard would have dropped the load on the sail, not increased it. I guess the other option is that the spar started to fail before I noticed it and made the turn worse than It would have been otherwise. My boat is a bit of a pig in a quartering sea and regularly has trouble holding course within about 20 degrees and the initial turn did not particularly alarm
me. I guess I'm a bit concerned that the new sail, which is made of a high end dacron rather than the cheap
dacron the original was made from, was too much for the camberspar. I kind of find that hard to fathom, but I'm really at a bit of loss to explain it. The sail was made by the company that does the OEM sails
so they should know what they are doing. I've had the old jib up in 30 knots, granted the main was reefed, but I fail to see how an unreefed main at 15-20 could have overloaded the jib. Last year Going to the Bahamas
I had the wind off the same quarter blowing 25 true in 8 foot seas and cruising steady at 10 knots, wing on wing with no issues.
The premium cloth is slightly heavier than the original, but I was planning on spending time in the tropics so I figured the extra UV resisitance would be worth it. Is it likely that 9.2 oz versus 8.6 oz cloth would overload the spar. The premium material is supposed to be a less transparent to the wind so it might be an issue downwind, but the performance of the boat didn't seem to be appreciably different than with the old sail, at least in the two days I had used it.
If anyone has any ideas what might have caused this I would like to hear from you.
By the way all you camberspar lovers, my Endeavourcat 44 won the class b multihulls division at the cruisers regatta
this year. The camberspar was probably the reason. A couple of my competitors asked me where they could get one after the race
