Looking for other Marsh Cat owners to hear about the boats performance especially to windward. Look forward to being part of the forum.

Welcome to the forum. I'm sure there are some Marsh Cat owners who can help you out on your information quest.

Where's Bokiea Fla? Come to Savannah GA and you can sail my Marsh Cat and judge for yourself.

Needs more than the stock 152 sail area to please me in light wind, surprises everybody in the 6 to 1o range and after 15, it's going as fast as it will every go , say 4 1/2 mph, so reef her down, keep her on her feet and stay dry. A 14 foot waterline is only so fast. This is not a Laser that will pop on plane. Pretty weatherly all the same, but keep her footing to cover distance. Pinching will get her close to the wind say for a mark rounding, but it's not the way to cover distance.

I agree with Buddy. I'm anxious to figure out how to make her sail closer to the wind than about 40 degrees. Its frustrating for me, because I am used to sloops which point much higher. Any advice?

Forty degrees is pretty good for any small, simple boat. I'd be surprised if a marconi sloop version of this boat pointed any higher with effective boat speed.

You are tacking through an angle of 80 degrees? An average racer cruiser sloop will do 90%. A sportboat like a Melges 24 might see 75%.

I'll be surprised though if the track made good through the water is anything like that.
Setting aside the cat rig, any wide beam boat with low aspect ratio rig is going to make more leeway. If it has only a canoe bottom and no lengthwise keel giving lateral area, and throw in the old time wedge of pie centerboard shape instead of a high aspect ration foil cross section be it blade or fin keel, ditto a barn door rudder instead of a blade, watch the efficiency losses accumulate. That's why I feel the velocity made good on the Marsh Cat is much better when you let her foot instead of pinch. The cat rig in general, all the sail area in one sail, not broken in two sections with one section acting in somewhat of a backwind, is actually more weatherly. The wide sheeting angle on a wide hull without inboard tracks for the genny can cost you. My 22 foot sloop is 9.5 feet beam, but the deck tracks are set inboard to the narrow cabin, sheeting as narrow as 6 degrees. The narrow waterline beam of 6 feet hepls, as does the 5' 10" daggerboard blade. In winds of 15 mph I often single hand with just the main and I assure you it points just as high or higher.
