Good suggestion, the waves in a storm come for below the dock pushing upward and removing the deck partially sometimes saves the dock in a very bad storm. I used lag bolts on a lot of the boards so they could be taken off with a ratchet However I never have done it. The storm warning time seems too short for me and that amount of detailed preparation, some folks do find the time and it is a good idea.
By the bye, everyone seems to be endorsing dock builders, so my recommendation is Mike Coleman.
He has an office on front street across from Belize bank.
