Much appreciated for that tony.I expect delivery of a Laser 1 boom sleeve this week (to retrofit my old boom) and can post dimensions after it arrives.
I tend to agree with the factories on this one that there has been plenty of time for people to fit sleeves to existing booms.
I don't know about that. I thought my '93 boat (145234) had a sleeved boom, but found out it didn't only last May when it broke. I would guess there are many people out there with pre-sleeve booms who might want to retrofit them (I know I would have, if I'd known there wasn't one in there...).
For those interested: I purchased a boom sleeve from APS and it arrived this week. It is for a boom on a 1978 laser (sail no. 53741). It is an 1/8 inch short of 36 inches, making it just shy of 900 mm. Diameter is 1 11/16 inches. I will try to add pictures.
Are you agreeing with my proposed placement, or not?Make sure you position the sleeve correctly...
You could always pull on some more outhaul, thus extending the foot of the sail again.Haven't read all the posts but another effect of more boom bend is that it makes the foot of the sail shorter, i.e. the clew and bottom of the luff get closer. This then causes the distance between
the foot and the boom to get bigger which causes a fuller sail, which is what you don't want when you're cranking on the vang to depower the sail. Thats why on a lot of boats that have a
loose foot they have a boom with a deep section which reduces boom bend.
Wondering why the boom vang is also called a kicker. Why would you ever kick it?
