Can anyone give me measurements for the leech, luff & foot for an anchor riding sail for a 22 foot sailboat? Our Capri 22 really sails around when we're at anchor and I'm thinking a riding sail will help reduce that a bit. I've got an old worn out pentex genoa that I can steal a corner from so I just need some measurements to get me in the ballpark.

Thanks in advance,

use a sabot sail or make a bridle instead of a one sided line for the bow of the boat--keep tiller midships and should not seem as much as you feel at present...have you tried lashing the tiller to the backstay to keep the rudder from flopping around and encouraging the yawing???

Bridle might be worth doing, though my cleat is only about a foot shy of the bow so not sure how much it will do. How do you tie off the bridle to the anchor rode so it doesn't slip yet you can adjust or untie it later?

The tiller was lashed but it didn't seem to help much. I'd have to buy the sabot sail but will look up the measurements as there should be plenty of fabric in the old 150 to make one.

I have an article from 1-2007, Sailmagazine.com that has a graph for figuring the square foot size of a riding sail. The article was by Jess Gregory. For a 22, it calls for a 12 to 13-square foot sail, but does not call for any particular lengths, only the "required" square-foot area.

When I had my Rhodes 22 Mack sails made me one at a very reasonable price.

Most times a properly angled 'anchor rode bridle' will outperform a riding sail in keeping a boat from 'dancing'.

The bridle is arranged so that the 'connection' to the rode (usually a multi-wrapped prusick knot) is AT the waterline and only a foot or two in front of the bow. The usual scope of 7:1 (4:1 for an all chain rode) would also apply for the bridle. The bridle is attached to independent 'chocks' / cleats well back from the stem on the caprail, etc. and contain/restrain each side of the bow, rubber tube chafing gear can be applied to the bridle near where it will touch the bow.

For me anchor rode bridles are easier and better than a riding sail .... although sometimes I use both when anchored in contrary currents + winds.

Run the bridle back to a jib sheet winch. Your choice of knots on the main anchor rode. Rich suggests a Prussick, I use a rolling hitch.

Prusik will not slip in 'either' direction when loaded, rolling hitch / taught-line hitch, etc. will slip in one direction.
