I also have a Belize 43
cat. This came with Dacron main and genoa.
I quickly replaced these with a Spectra base load path set. But, depending on the budget
, the ultimate sails
for performance cruising are triradial cut Hydra Net sails
This Hydra Net, is a woven Dyneema
cloth from Dimension Polyant sail cloth manufacturers. This offers the best in shape holding, strength, UV resistance, and long life.
In addition to the lower stretch construction, we increased the roach in the head
and upper leech. This is not a square top but has about the same sail area of the square tops, keeping all the battens parallel to the boom. With a square top design, the head
of the main needs hardware
to release ithe head cars from the head of the sail, to allow the main to stack for a cover. The "elliptical" head offers about the same performance with out this hassle.
On the Belize 43
genoas, this large size offers good performance in most sailing conditions. I wouldn't want to go smaller. We reef the main in about 20 and a small roll in the genoa in about 25. The correct cut, sail material, and having a foam or rope
luff should give this sail a good usable shape when well reefed.
We do build multihull
sails but I am not posting
I have been pleased with the performance of the Belize
43, even after owning a racer/cruiser before this. Increasing the area of the main, using better sail materials than Dacron and adding a good off wind
sail, made this boat a good performance cruiser.
