Make sure you have your open water certification and a drysuit handy. You'll be busy.I do wonder how those IPS drives would fare in my home cruising grounds in Maine. They look like pot warp magnets to me.
That has 56 Chevrolet Nomad written all over itGuess so. Even more off subject, but hey ho!, steampunk plate or faired rudder? Good old Brunel 1845.
Back to the subject and far smaller at 18ft similar length to the dinghy's' and cats I have owned. I like the lines of a good old 1960's US built power cuddy Dorsett Catalina design. Conflict of interest - I have one similar in the UK (not as nice as this though)

Damn. I just have to know which one!I had a big
argumentdiscussion with a fast ferry builder in Australia who wanted to build plate rudders like you show. Finally convinced him to cover his plate with foam/glass to make me an airfoil. It was a bit fat but not as draggy as hauling a vertical cylinder through the water.
It's hard to convince people. Humans have bad intuitions about drag. No matter how many times I look at this picture, the fact that these two profiles have the same drag feels wrong to me. Probably the very different volumes tricking my eye.Finally convinced him to cover his plate with foam/glass to make me an airfoil.

Marine Engineering Consultants, Coomera QLD. Otherwise super nice guys and very good build quality. Just read they went into liquidation late in 2020.Damn. I just have to know which one!
CD is related to a reference area, Drag is proportional to S x CD ! Likely the reference area are not the same
Nice boats, built like shipsThe classic British powerboat for sailors who have hung up their oilskins. Dale Nelson. Basically a pilot boat semi-planing hull. Narrow, so limited interior volume. Good seakeeping.
