Here's a start
Thanks, folks. I have taken my Catalina 2 5 thru 5-footers on Lake Michigan, and there too the boat handled them much much better than the people. Naive question: why is fractional rig so good?--josh
Josh,
Nice way to ask it... It is not "better" but it is "good." :nerd:
Coming from two smaller fractional rig keel boats, our present boat was our first masthead rig.
I always liked having the main driving sail (and largest sail) being the one with the most controls. Unlike the genny that can flap around when you are letting it out or in, the main is always "attached" on two of its three sides. With a modern 6 or 10 to 1 main sheet system and decent ball bearing traveler it is easy to position. It has several other lines you can use for fine tuning the shape all the time. Additionally, with a fractional main, you can use the backstay to bend the mast and flatten or depower the large main in heavy air. All this from the cockpit.
Strictly IMHO, next best thing is to have a rig where the E is about equal to the J, in other words, the foot of the main is close to the base length of the foretriangle. Our Olson is this type of rig, i.e. a "balanced" rig.
No wrong answers, though. All rigs have their plusses and minuses.
Hopefully one of the experts will check in and correct or augment my remarks.
Cheers,
Loren
