Doel-Fin improves overall performance - even on boats with well designed hulls
Save up to 30% on fuel consumption
Faster out-of-the-hole for happier water skiers and wake boarders.
Maintain lower planning speeds
Simple 15 minute installation (hardware included)
Doel-fin is the original hydrofoil developed by an aeronautical engineer to improve overall performance on all boats with outboard motors or outdrive units. Molded in two pieces of guaranteed unbreakable, High-strength plastic, each foil is designed to flex independently to absorb shock. The positive effects include greater stability, consistent planning at lower RPM, faster out-of-the hole performance, better gas mileage, steadier turns, higher top-end speeds and lower bow rise at all speeds. Doel-fin is designed for use with small motors, big motors and inflatable dingies.

What a great product! Mounted them on a 30hp 14 foot aluminum boat with a console. (In about 10 minutes) Its a suprisingly heavy boat for it's size (flotation, full floor and side boxes, foot operated trolling motor fuel, batteries, happy wet dog, drunk friends, bla bla bla) and took forever to get on plane. Not only does it plane in about half the time now but I also gained 2.2 mph! I can also plane out and throttle back quite a bit and still remain on plane now, where as before it was wide open throttle just to keep it up and out.
Previously when crossing wakes the bow would rise way too much so I'd have to throttle waaaaaay down, cross, then throttle back up. Now she plows through the waves like butter, remaining on plane and stable the whole way through. The difference is truly night and day!
I can't comment too much on fuel savings, but it stands to reason I'll see an improvement if I get on plane then throttle back down.
I installed Doel Fin on a 14ft Lund with high sides and a built in floor and bait well. My motor is a 20 HP Tohatsu 4-Stroke. It was a terrible rig. Took for ever to plane and then bounced so bad it was not drivable. When I put 150lbs. on the nose it would plane and go about 18 MPH. After installation the boat comes right out of water and runs great. Top speed 24 MPH nose always stays down and can plane at half throdel. Don't need weight in front of boat. This thing is fantastic.
I never write reviews, but in this case I am. The Doel Fin is absolutely fantastic if you have an inflatable RIB! Mounted on a Suzuki 20 HP, new engine on 11' Rib. While I had good out of the hole performance, adding the Doel Fin made planning almost instant with very small amount of throttle. Can now plane at about 9 knots, making the ride in choppy water much easier. Cannot say enough about the change in performance. Did not lose any top end speed either.
