Appropriate sail area
 

Appropriate sail area


Hi everybody! I have a slight design problem which maybe better answered by
boat users then boat builders.

The rig will most likely be a Bermuda sloop (main + jib) or possibly a
Bermuda Cat rig. The bare hull will be made very lite because it's a trailer
sailer to be easily handled.

The size is very large for a 1-man dinghy due to hiking gear, cameras etc
etc. LOA 5,60m (18') x 1,95m (~6½')
2 x 40Kg (pivoting centerboards) draft only 0,7m and a heavy rudder, 10Kg.

Here are the total weights incl. Crew, hiking equippments etc. (calculated):

300Kg (~750lbs) sailing fast, for fun.

450Kg Main_design-weight_ Safe _cruising /transport_ with gear.

550Kg (~1400lbs) Max (used) load

How big a sail would I need /dare to take?
You could also give me an appropriate SA/D Ratio.

** My Sandpiper 565 seems to be similar in size.
mainsail = 94 sq ft
genoa 73 sq ft

How do you find your sailpower?

What characteristics would you give the Sandpiper hull?

Just got the boat this year and did't get to use it due to wife's illness &
operation that wiped out July & August.

So sorry.... hope it will turn to the best!


If any one else has comments on the sailpower on boats with sail area around
9-11m2 (90-130sqft) I'm eager to listen.
