Ye gods! It's hard to right even a small cat. You have to know what you're doing. A small sailboat is much easier. I don't know if you looked at the pix of the huge powered cat which capsized, but it's hard to see how the captain did it. Somehow, it looks, from the reports, that he got abeam of the seas. Get water rough enough and you can put almost anything under that way...Reminds me of an incident that happened almost 30yrs ago when my brother and his friend rented a small personal cat out of Gulf Shores (or was it Panama City - I can't remember), convincing the owner that they knew what they were doing (they didn't have a clue). They ended up capsizing several miles off shore, didn't know how to right the vessel, caught an outgoing current with the sail that was now pointing straight down, and drifted halfway to Cuba.
My brother and his friend said sharks were literally circling the boat waiting for one of them to fall in from the bottom of the hull where they were perched. They had their "I love you man" conversation and everything, thinking that it was only a matter of time. They were eventually spotted by a passing cargo ship who thankfully called the Coast Guard, who came and righted them before towing them to shore. They had been drifting for about 24hrs (SMH). Idiots.
Glad your friend's daughter made it out OK.
I agree. It's very scary when that windward hull lifts off the water. Speaking of unstable, I used to own a 22' Venture. Nice boat. It had a hefty drop keel. You let it down with a winch and then shot a 3/4" bolt through a hole in its stowage compartment through the matching hole in the keep and then through the hole on the other side of the stowage. You could also thread the nut on a few turns for more security. It was a nice feature, but most of us who had them sailed without the bolt, because the breezes around here don't generally require it.Scary. I've done the cat charter before. While more comfortable, they are definitely less stable than a mono when you get the sail in high wind.
