Hi Greg, A speed of 20mph is way more than the natural hull speed for a 17 boat, so you can safely say that it is well and truly planing. Atkin s first everMessage 1 of 12 , Dec 14 12:05 AMView Source
A speed of 20mph is way more than the natural “hull speed” for a 17’ boat, so you can safely say that it is well and truly planing.
Atkin’s first ever Tunnel Stern design from 1922, “Mischief”, is the fastest of any of them and is quoted as achieving 23mph with a 30Hp engine. It was a bit longer at 23’ which would have helped I suspect, but it gives you an idea. The shape of the tunnel may have been a bit different too, but the plans haven’t survived, so far as I’m aware, so I guess we’ll never know.....
Thanks for the Happy Clam Skiff! The plans show a speed of about 20mph with a 10 HP engine...any speculation what speed might be obtained with a 15 HP engine? I understand this is not a planing hull and it must "work" it's way through the water as opposed to skipping across the surface, so I'm not so sure more power will work at all. Any ideas out there?
Around here there is A LOT of water, both fresh and salt and there can be a long way to go to get to your destination. My target / minimum speed is at least 25 mph and I am wondering if any of these Sea Bright Hulls can manage that speed.
I also like the seaworthiness of these hulls as it would see some near coastal ocean water.
