In searching through the archives I found a thread where people were talking about drilling a small hole in the back of the rudder to attach a rope and then using a block and tackle on the mast crutch/pole to raise the rudder.My question is this....Is the rudder on the 23.5 a solid core or is it foam core.If you drill a hole into the back of the rudder is there a solid spot (solid fiberglass) that you can drill through?Worried about water leaking into the rudder and causing delamination or something.any help would be appreciated....thanksJames
