Does a Hydrofoil make sense on a Pontoon?

Just curious if having a hydrofoil would have any benefit to a pontoon? Perhaps this has already been discussed?

The general concensus here is no.

Re: Does a Hydrofoil make sense on a Pontoon?

I have one on my 24 footer and it helps with the ride. I don't have power trim and if I set the engine in one notch the front of the pontoons plow the water. Without the hydrofoil the stern digs in. When I first installed it, it gave to much lift, so I trimmed an inch off each side and tested it again. I ended up trimming about 2 inches off both sides to get the best ride at my normal cruising speed. I've been running it that way for 20 years and it hasn't caused any problems.

From my own experience, definitely!

The whole reason I ended up on this site is from my search to find out if I could get the kit that my dad had on his 24-foot pontoon boat when I was a kid (back in the '80s). I wouldn't want a pontoon boat without it.

The pontoons had welded aluminum triangle "wings" on each side of each pontoon, running all the way back. With a 90 HP motor, we could pull two skiers or one of those multi-person tubes. It acted like a standard pontoon boat until it hit a certain speed and then it would suddenly jump out of the water and skip along like a bass boat. The only down side was that you felt every little bump as though someone was using a sledge-hammer under the seats, so it was better to run through smooth water.

I've looked for a few years and haven't found anything like it, just some kind of third pontoon add-on in the middle. I thought I remembered my dad saying that it was called a "go-fast kit" that was installed by a custom boat shop somewhere in metro Phoenix. Whoever did it, did a great job, since the aluminum welds looked perfect. I really wish I had that boat now.

Bit-Smacker, The OP was asking about a hydrofoil which is a wing device that attaches to the antivent plate on the motor. What you are describing are lifting strakes welded to the pontoons. They work 2 different ways to produce 2 different results. The strakes allow a pontoon to acheive plane. I'm not sure what the foil is supposed to accomplish, but most people say they they add very little and may reduce performance. I have the strakes, have no experience with foils.

Cool, thanks! I just did a search and that's exactly what I was looking for ... "strakes"! Now, I just need to find a place that can install them.

Thanks, again!
