PS37 genoa -- what size?

5852 Views 22 Replies 10 Participants Last post by  Lantau
I'm getting ready to replace all of my sails. Currently I have what I think is a standard PS37 cutter setup by Ullman Sails, namely a main on battcars, staysail on roller furler, and 120% high-clew genoa on roller furler. It's easy just to get replacement sails from Ullman, but as I have gotten into this process I have been advised to do different things. One sailmaker wants me to extend the foot of my staysail. Another wants to lower the clew of my genoa to increase its size for light winds. Another wants to change the main. I'm not even mentioning the complications with installing a new sail on my current battcars (easy to do, hard to choose what to do).

What are those of you with the PS37/Crealock 37 using for sails? Right now I'm inclined to take the advice to enlarge the genoa a little bit. The PS sail plan for the boat includes a 130% genoa as one of the possible sails, so I think I should go for this at least. (I should point out that I'm calling mine 120% only because that's what US sails calls it. I haven't compared the measurements to get an exact percentage.)

Yesterday in 10-13 knot winds the boat was nicely balanced, but I started out in about 3-5 knots and a bigger genoa would have been nice to have. This boat was definitely designed for Force 4 (like most sailboats?); it's just perfect at those wind speeds -- such a pleasure. The boat sails itself. Less wind can be a tiny bit frustrating (passengers always want to go faster...), and more wind is also a pleasure but of course livelier as the wind picks up. In 20+ knots I'm usually on a reefed genoa and reefed main, so having a larger genoa wouldn't be any problem (it would be reefed down), assuming I have enough line on the roller furler. The benefit of the larger genoa would come in light winds.

Advice on the PS37 genoa (or sails generally)? Experiences?

If anyone wants to recommend a sailmaker, I'd welcome that, too -- but I think that opens a can of worms.

Many thanks.

I think a lot depends on where you are sailing.

On Crazy Fish I have had a 130% fairly low cut genoa, a 105% Yankee and currently a 135% fairly high cut genoa all on a Harken Roller Furling.

I have a hanked-on staysail and the stay is detachable.

For sailing in San Diego with its normally light winds the 135% work well and the higher cut works better for visibility. The visibility comes in handy when sailing on the bay on weekends. Offshore not so important. The staysail is normally not flown and the stay is detached so tacking is much easier. The staysail gets hanked on but normally stays in its bag when sailing to the north where the wind can be stronger. I don't think I get much out of it when using it with the 135% so its normally flown when the wind increases and the genoa gets rolled in.

With the 105% Yankee I used the staysail a lot with the Yankee and would typically gain a 0.5 knot or so when flying it.
I used this setup quite a bit when the boat was based in Los Angeles and made fairly frequent trips to the Channel Islands where the winds tended to be stronger. Easy to adjust the sail area to match the windspeed.

In the future I am looking to add a collapsible bowsprit to the boat to get the mounting point for the asymetrical spinniker out in front of the bow pulpit. It will also be used for a furled Code 0/screecher type sail and then I may look at having a new Yankee built for the boat or at least a smaller genoa built (120 to 110 ?).
