Hi all!! I am about to aquire a 31 irwin with a missing centerboard .. I have a 27 irwin with a good board I am thinking of scraping ( the boat not the board) and it has a good centerboard already out ... does anyone know if they are the same size and if I can use the 27 board in the 30 ... is it possable to put the board in with the boat in the water ? also need the sail size for the main sail ..blown away by hurricane don't ya know. This is a fixer upper of the first order so will be full of questions ...thanks jd
