Hi On lifting out my LM27 this year I noticed a lot of water draining from inside my rudder. On investigating I noted that there was no seel at the top and water was allowed to fill it freely. Is this normal as I don't think it will do the internal frame any good. I am thinking of replacing the standard fibreglass rudder with a stainless steel extended one. Can anyone tell me if these can be bought of the shelf or do they have to be manufactured. Allan
