Bianca 27 sails: questions
How much is a new mainsail for a Bianca 27?
From A$1,588.40 in Dimension-Polyant Optimum Cruise with 3 leech battens and a full-length head batten, or A$1,744.60 with 4 full battens. C-Breeze, the long-life cloth, starts at A$2,130.70. Every mainsail is cut to the Bianca 27 rig (P 8.70 m, E 3.35 m) with two reefs.
What size genoa does a Bianca 27 need?
We build 110% to 150% LP for the standard rig (I 9.91 m, J 3.40 m). Pick a smaller genoa for a windy home port and a larger one for light-air sailing. Furling genoas start at A$1,486.10.
What size spinnaker fits a Bianca 27?
A Size 2 (43 m²) asymmetric suits the Bianca 27 fore-triangle. It starts at A$1,406.90, or A$2,036.10 with a dousing sock.
What size storm jib and trysail fit a Bianca 27?
The Offshore Special Regulations cap a storm jib at 5% of I squared (4.9 m² here) and a trysail at 17.5% of P × E (5.1 m²). That makes our Small (4.5 m²) storm jib the right size. No stock trysail 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.
