The new plate I want to try to hold off on until its up on stand in the winter, and the mast is un-stepped. I definitely want to have this type of setup rather than drilling holes in the deck, but un-stepping in the water isn't a wise mans game and I really want this done in the next week or two...so I'm thinking I'm going to create my own "temporary" solution that can be quickly adapted to the base plate system: using tangs attached to the existing hinged plate for mounting the turning blocks (see a previous reply I made with a quick concept drawing), which could them easily be transferred over to the base plated system in the winter.
