Match the Weather

I've recently purchased an ODay 26 furnished with a single roller headsail. Probably 150+%

What sail would be appropriate for winds 20kn-25kn??

Somethin' a LOT smaller. We use an 85% here on SF Bay with the summer winds in that range. And reef, reef, reef the main. Did the same with our C25.

We have a 25' center boarder and in 25K true wind, we carry a reef in the main and roll our 90% jib to about 40%. We'd put in two reefs (if we had a second). Remember- Double the wind speed quadruples its force. Ernie

Stu, ebsail =

Thanks for your input. How do I get the measures for a 90% jiob??

Get the specs for your boat, or more simply measure the distance from your forestay to your mast. Any sailmaker will know how to do this. Let them do it for you.

The distance from the headstay to the mast on a 25 is 10'6" . You can use a 100% jib and partiallly roll it up on the furler when things get to 25K. Over 25K with highter gusts, yu should be headed home anyway and would only be using a sliver of jib and a heavily reefed main.

The full specs are here:

Remember that the headstay to mast distance (J) is not the sail size. The sail size number is a percentage of the LP (Luff Perpendicular), the right angle distance from a point on the Luff to the clew divided into the J measurement.
