I have a set of brand new Weaver removable dinghy chocks for sale. I bought these and found they are a bit too small for my 15' dinghy, so I need to have custom chocks made. They are a very high quality, all stainless product, and include the optional swivel feature for a perfect fit to the contour of your dinghy hull. These are also the larger 3.5"x7" model and include the optional base plates that make them removable so you can have a clear deck when desired. The base plates screw to the deck, then the chocks slide into the plates and lock into position. It's a great system - I just wish they made them one size larger.
I paid $930 for the set of 4 chocks and removable mounting plates. I'll let these go for $750 plus shipping.
