Mclaren Clockwork Submarines

U56 has a 2 plate top and base hull with a single 80ml ballast tank in the nose, she has a 90mm beam that allows for a large powerful free spring motor. The emphasis is on speed with this particular boat its a sleek no frills design without any in flow protrusions, the lead keel weight is two separate plates riveted through and edge feathered as opposed to my normal single sheet wrap around arrangement, the skeg on the tail of the keel serves to protect the prop also providing added lateral stability. The result of all these shenanigans?A superbly balanced,fast and stable boat that for some bizarre reason reminds me of a killer whale.
