It’s amazing how often I use the stack of dive weights I needed to get neutral when wearing my Arctic-level dry suit, (bought when we were cruising the high latitudes) to hold stuff down or together while glue is kicking off.
In the photo above the weights were invaluable while I was splatting¹ new TreadMaster on our companionway top step.
The heft and curved surface of dive weights works great for this function.
Worth having a few around in the workshop even if we aren’t divers.
¹A technical term Phyllis and I developed while spending three months covering the deck of our McCurdy and Rhodes 56 with TreadMaster.
