F36/Tri cabin exhaust question.

Post by dab62 » Thu Jan 23, 2020 3:03 pm

Well, the winter doldrums are really kicking in. So what else to think about, but boats! I was always curious why the F36( and F32 for that matter) did not utilize the underwater exhaust of the Tri cabin? Although a little scary to have 2 large holes in the bottom of the boat, the noise reduction, and reduction of the station wagon effect seem like a nice trade off. Plus no critters to enter the exhaust in the winter! I was also wondering why the underwater exhaust did not cause appreciable cavitation. Or use side dumpers like the Internationals.

I assume its because Trojan did not want to run the exhaust thru the aft cabin , they did the same on the F40 . Maybe Bob knows or can find out for sure .

Port exhaust would have gone straight thru my bath tub.....
I needed a less expensive hobby, so I bought a boat!

The Tri Cabin had a problem with station wagon effect. The CO would come up the transom and into the boat.
The answer was underwater exhaust.
The underwater exhaust of the Tri Cabin amazing engineering.

The exhaust on my Tri is pretty awesome....... can hold a normal conversation at cruise speed

I always thought so as well. That's why I wondered why it didn't cross over to the other F boats.
