Just as a follow up to Alan’s original post, as a Nc39 owner which was built in 1994.
My sails were made by Peter Saunders who is based in Lymington and purchased just after I bought her in 2010. The original North Sails from 1994 were not too good.
My main is a fully batten sail in the Vektran material and has three reefing points.
The Genoa is sized at 135%, again in Veltran material on a Furlex 300S roller reefing system.
For heavier weather I also carry a 90% jib again in Vektran material.
For light winds there is a Cruising Chute which a previous owner had purchased from Diamond Sails. Not used.
I have spoken to another Nc39 owner who has a 150% Genoa and in mast reefing on the Main sail. So as with most Nauticat yachts there are quite a few differences between the same model.
My experience during the last three years is that my main sail is very powerful and I have not had problems putting in or taking out reefs while sailing. The genoa is also very flexible either fully unrolled or with a few rolls in heavier weather. Not used the jib sail or the cruising chute!!
