Well, here we are heading east and HUNDREDS of motor boats are heading west, all within feet of me. Since the motorboats are coming on both sides, I decide to edge toward the shore. When we are in about 5 feet of water I ask my son to raise the centerboard (a 600 lbs piece of iron) with the wench, the cable comes loose. We are sitting on the bottom (at least the centerboard is). We can no longer bob up and down, only sway from side to side, taking on water. I decided I have to swim under and secure a rope to the centerboard. While feeling for the hole, I have no mask, I slice my hand on barnacles. We have blood in the water and my son yells "SHARK!" Everyone panics, but I have to keep us from capsizing. My wife is on lookout with a dip net in-hand, like that would stop a shark. I finally got the centerboard up enough to get underway to the marina. Obviously we made it. My wife said, "NO MORE". We sold the boat. I now have a Macgregor 26s. The centerboard can be raised with two fingers. We are a sailing family again. Thank you Macgregor. That adventure is over, Thank God!
