Re: Dolfin planing plates for small outboard

Years ago, I had a flat-bottom, 11-foot, forgotten-name dinghy fitted with a 15hp Evinrude 2-stroke and dolfin plates. Call it planing or call it flying, that rig was scary with just me and the fuel tank in the boat, because most of the boat was in the air.

Whoa, over react often?, I have an 8' air filled mattress with a 3.3 merc and I can get it on plane. Also I can assure you, it's half deflated sides and broken roll up floor aren't doing anything for its hull form.

I don't expect everyone to agree with me but your rude and juvenille response
is unwarranted.

Big difference between a flat rigid airboat bottom and the equivalent of an air filled mattress.

I used to have an Achilles air floor dinghy with an 8hp engine that would occasionally plane with my 240 lbs. in it. I say occasionally because the bottom had to be clean and the stars had to be properly aligned.

One way to find out, try one. All it costs is a little bit of money & a few holes in your cavitation plate.

I disagree, I've had 3 outboards onto which I mounted the Dolphin or similar plates and it has made a world of a difference each time. No cavitation anymore and the dinghies really do go on a plane much faster. I had 9.8HP Tohatsu engines but I think that smaller engines will profit and gain performance as well.

Re: Dolfin planing plates for small outboard

They wont work for your dinghy as I doubt you can plane with a 3.5.

The dolphin fins do slow you down a bit. So they are only effective making a boat and ob that planes do so faster and with more stability when on the plane.
