Balboa 20 sails: questions
How much is a new mainsail for a Balboa 20?
From A$973.50 in Dimension-Polyant Optimum Cruise with 3 leech battens and a full-length head batten, or A$1,101.10 with 4 full battens. C-Breeze, the long-life cloth, starts at A$1,084.60. Every mainsail is cut to the Balboa 20 rig (P 6.40 m, E 2.65 m) with two reefs.
What size genoa does a Balboa 20 need?
We build 110% to 150% LP for the standard rig (I 6.31 m, J 2.68 m). Pick a smaller genoa for a windy home port and a larger one for light-air sailing. Furling genoas start at A$704.
What size spinnaker fits a Balboa 20?
A Size 00 (27 m²) asymmetric suits the Balboa 20 fore-triangle. It starts at A$896.50, or A$1,421.20 with a dousing sock.
What size storm jib and trysail fit a Balboa 20?
The Offshore Special Regulations cap a storm jib at 5% of I squared (2.0 m² here) and a trysail at 17.5% of P × E (3.0 m²). No stock trysail is small enough for this rig, so we quote one to fit. No stock storm jib is small enough for this rig, so we quote one to fit.
How do I check my boat matches these measurements?
Measure I, J, P and E and compare them with the rig table. We confirm every measurement with you before the sail is cut.
