The International 505 is a one-design high-performance two-person monohull planing centreboard dinghy, with spinnaker, using a trapeze for the crew. While it is a high-performance boat and demanding in a blow, the 505 is an extraordinarily well-handling craft and is easier to control than many smaller trapeze boats. I have two mainsails a spinnaker and stuff luff. Needs the forward rail wood replacing soon but the just screw off.shown in picture these are great boats see on line https://en.m.wikipedia.org/wiki/505_(dinghy) Viewing at calshot sailing club which is a great club and cheap to join
