Usually I am the only one on it. A couple of times I have went out and have had water come over the deck. The bow had gone under. I quickly turned the rutter and released the gib/jib.
The mast is about 20ft high, it attaches to a clip and a pulley is at the top and that is how I raise the sail. There is definately way too much sail for a newbie like myself.
Please forgive the fact that I don't know all of the technical terms.
