.... well designed steadying sails are NOT designed for propulsion but might add speed as a secondary benefit...
Willards almost always came with a small sail. My Willard 36 came with a sizeable rig and my Willard 30 also came with a small hanky sized sail. Both boats have more ballast and less above area than a manatee. Unless there is a relatively significant sail plan as shown on the DD Coot with tanbark sails in this thread, I don't think it's a good use of time or money. For me, it took a half a hurricane on the beam to put a set on the boat.I’m looking to see if a steadying sail is worth the effort. If so does anyone know where to get one or at least the recommended size?
Thanks
Agree, but they can help if the sails, in total, are not handkerchiefs.
That’s what the canvas guy here told me too. I just got a rough estimate of 700.00 for. 5’ tall by 8’ long and he wants to install a track up the 5’ Of mast. I was looking to slow the rolling a bit while cruising.
Thanks Tom
The right way and only way to have an clue if it will work is to run the numbers.....
Which unless you already have the stability numbers for the boat will be very involved.
Next best is take it out in some heavy wakes to get a rate of roll and the approximate roll axis.
The point is... the OP doesn't know, I dont know and you dont know.
Your guess is just one of 3. (Plus it is the entire sail that helps a riding sail, even the corner boards if even used...I dont believe I have on the sails I have seen. Also...it can be bigger than just 5 feet tall uf there is more room on the mast.)
I have no idea what force it would take to slow or reduce the roll of a KK Manatee or a Willard.
There are shortcuts in estimating stability...like eyeballing what a 200 pound person does to trim...but if one is going to spend the money....I like crunching some reasonable data first.
Rolling chocks get all over the map reviews too. What works on one hull doesnt necessarily on another. But yes rolling chocks are another viable direction to go after similar research is done to eliminate a steadying sail.
And possibly a set of both in lesser sizes may be a better or worse answer that I haven't even thought about before. Food for thought.
Is that a fairly large motorcycle on the upper deck of Man-A-Tee?
