IJust a quick note on fore triangle dimensions - last year I had 2 boats, the pocket cruiser
was an Albin Cumulus (28), fractional rig, 135% genoa with tafetta fill (new when I bought the boat) - awesome sail, very much like Roverhi's description of versatility and performance. The new boat is an O'Day 31, masthead rig, BIG fore triangle that provides more than half the rig's overall sail area. This one came with an almost new 135 as well - Neil Pride, not a heavier sail than the Albin's 135 in terms of cloth weight, but being seriously bigger in dimensions the net weight seemed to kill the shape, so under 5 kts, no fun.
Long story short, I found myself furling
the 135 on a consistent basis in 15+, so I bought a 115% of similar grade to the headsail I had on the Albin and picked a used blade off a Cat 30 from Masthead sails
(consignment shop). I have yet to see how the new sails
perform as the boat is still on the hard
(waiting on new rudder
, ETA next Friday, but that's another story).
