Good morning

I would have liked to get an opinion from someone who owns the Code 0 sail

I've been offered a smaller sail of 85m2, whereas the original sail is 94m2

so it will be smaller and flatter, it should sail even better upwind

What do you think: should it be a little smaller than the original or does the original already catch the wind very well

I look forward to your feedback.

I wish you a wonderful holiday season

The 'rule of thumb' for a C0 is that it should be from 1.8 - 2.2 x the area of your working jib. As you say, smaller for going closer to the wind or use in stronger conditions and larger for lower wind speeds or reaching. The choice really depends on how you want to use your boat, but when I ordered mine I said I wanted it to cover a large angle as the boat is always sailed single or short-handed. The result was a sail perfectly usable between 60-140' but which can be pushed to 40-160' in the right conditions. I strike it when approaching 16kts AWS.

It would be worth talking to a sailmaker who can give professional advice based on how you sail your vessel; that could save an expensive mistake.....

Merry Christmas!

Hello Alex - I regret I don't have the exact figures to hand but it is certainly large for my 12m vessel, a full radial 'crossover' between a pure Code 0 and a gennaker set on a Facnor FX2500CZ and a very light furling line integral to the luff. I'd tried a top-down furler before and hated it but this sail has been brilliant; easy to use and effective.

You might find some of the details you want here: https://sailboatdata.com/sailboat/hanse-458/" rel="nofollow - HANSE 458 - sailboatdata , but as I wrote I do recommend talking to a good sailmaker. That said, if you've been offered the 85m2 sail at a good price, you can rig it easily on your vessel and you're not a 'speed freak' determined to squeeze every last tenth of a knot then its probably perfectly suitable. As the 458 has a jib area of 48.94 m2 then the recommended area is between 88-107m2 anyway. However, do not assume that the smaller sail will be flatter; the shape of the sail is determined by the sailmaker using some 'interesting' mathematics which cannot be determined from the IJPE numbers alone.

All the best!
