How much reefing Manta allows only one reef in the main sail. Anyone any idea if that's adequate with 5-6 bft? ... 6 Tue 4th Oct 2016

Thanks, that's is interesting.

Do you have an idea how much of the mainsail (percentage) is taken away by the 1st and 2nd reef respectively on your boat?
Let's presume the jib is more or less of equal size on each boat.
Kind regards

I think there are different reefing set-ups on the Manta's. Just to give an example, when I got mine she had a roller-reefing boom, but sails for two reefs.
Now I have two reefs. I use the first very often (as last time yesterday). I have tried the second reef only once, and found it made the mainsail too powerless: lee-helm and hard to bring the bow through the wind to tack.
Still, I like to know it is there when the wind really picks up.
To answer your question, I find 5 Bf can easily be managed with the first reef. 6 Bf gets hard work, but the 2nd reef does not seem to help all that much. Stronger than that, I just watch from the bar.
All of this applies to sheltered waters. Wind is no trouble, just shorten the sails. But in open water when the waves start to build-up, it is no place to be in a wee boat weighing less than 700 kg.
