Or any small boat foredeck...I have spent a lot of time up there in racing sailboats--15 to 20 foot seas are about the max--but it is quite a ride and very difficult to work. I am courious about the 400 feet of 7/16" H T chain--this weighs about 2.5 lbs a foot or around 1000 lbs. Is it really necessary to have the 400 feet of chain? What I am aware of deployment of sea anchors, short lengths of chain are desirable--both near the anchor to weight it down and from the boat for chafe protection and keeping the line down--and preventing it being pushed back toward the boat--but 400 feet seems a lot. Also how do you let this 400 feet of 7/16 chain run out, with out risking damage to your boat or yourself? Thanks, Bob Austin
