I own a 41' center cockpit Island trader 1984. I was looking for more specs or info.(heigh of masts, wiring diagrams, blue prints, ect.) I was told that the ones with the dragons carved into the bow are trans world versions, which are more rare. Does any one know the difference if any. Also wanted to know what type of wood the masts are made of since I was told that wood rot is common on these vessels.
