Thanks for sharing this, I was intrigued by this concept when I read Peter R. Payne’s book: Design of High Speed Boats.
Don’t know how well the sea knife worked, but it was good to see a new fresh approach to the planing hull problem.
Did that, or something similar make an appearance on Tomorrow's World back in the 70's?
Seem to remember a direct comparison made (side by side) with a conventional Vee hull in the program) Kind'a wave piercer.
Don't remember it being that big though.
Showing my age.
I remember that too. It was filmed in Poole using an Avenger 19/21 as the conventional vee boat. Tomorrows world report was very biased against the Avenger boat as I recall.Think I've got an old Powerboat mag somewher with a report
Cor,you`d think it was the best thing since sliced bread,until you look at the GA`s and see engine sumps scraping pure cored structure,or waterlines drawn nice and level with min draught for that passenger arrgt despite the dayboat version showing the true floatation line.The size of those guns in the military version indicate a corvette size craft,so we go from 38ft to 200ft in one fell swoop.The times I`ve come across these crackers in the past,really does make one wonder if these people can make a living in boat design.
