In Mast Furling Mainsail-Reefing

[SteveSJM]

I've been using an in mast furling main for a couple years now and when I reef it's by guesswork, where as when you slab reef you use cringles, so you can know how many reefs you've put in. Does anyone know how to calculate a way of marking the boom so I know how much sail to furl in for 1, 2 and 3 reefs? Just so it's quick and easy!

Cheers

Steve.

Isn't the advantage of roller furling suposed to be tht you can shorten sail to exactly what you need rather than in preset 'slabs'?

Our main has three coloured dots at en equal distance to use as reference points.

Mine too..... first one about 1m from luff, and then two more at 3/4m each from there

With rollers on both you have complete flexibility.

It really depends on the rig but with a mast head rig, the genny is quite powerful. Therefore, reef the genny as normal. Then reef the main down to ballance.

Not a problem if you have full length vertical battens!
