Maybe not so great having join in middle of a windsurf board, but maybe a replaceable nose section on a beginners / free
styleride board could be a good idea i.e. the manufacturer provides you with two nose sections - one made of a soft flexible material for those so inclined to regularly catapult, and the other to match the board construction once skill level has improved.
This could double the life of a board..........hang on, manufacturers wouldn't want that now
