As much as the cool factor would be on a twin jet tri-toon with a REALLY open rear layout, I can't imagine the racket a pair of 1.8's would make inside giant aluminum tubes! Sound deadening would have to be on point to not be on the wrong side of unbearable.That makes complete sense on space savings. The outboard does change the whole layout of the stern of the boat. I had not thought of it that way. But fuel efficiency would only be worse on that outboard if you were running it WOT. As it takes plenty to push his 24' Tri up to 30. But cruising, that's a different story. Pushing around 15 people for weeks on his 35 gallon tank. It literally sips fuel. But obviously too many variables to compare.
In the fishing boat world, aluminum boats from 16-24' long will weigh much less than a comparable fiberglass boat. In fact, larger HP outboards is what has allowed some boat MFG's to go back to making fiberglass fishing boats, as they are quite a bit heavier in comparison.
The only reason I bring up Pavati in my previous statement, is those boats are overbuilt. Sort of like the aluminum river boats. Much heavier metal, and much more put into the strength of the hull and welds. They are true works of art for sure.
I had no idea aluminum was that much lighter in final construction than fiberglass. I'm going to have to dig more into the construction of the two hulls. Has to be added material from the fiberglass to maintain rigidity that is causing the weight gain. Everything else in the word seems composites are lighter. Airplanes, Bicycles, motorcycles, cars, etc. It has to be something with the spars are laid out, general fitup practices, or something like that.
Buddy with the 24' Berkshire typically runs at or close to WOT at around 30-35mph. He thinks 20 is too slow. He usually beats me to the hangout spot by a minute or two on a 10mi stretch. I can hit 42, but can't maintain a 35mph average it seems. I scrub speed badly on turns, and have to throttle up/down along the way for wakes/waves/traffic. His is like a tractor of "set it and forget it" and it runs that same 35mph if it's turned over hard in heavy wakes or slipping along straight in calm water. I'm certain his love for WOT usage is what causes him checkbook pain at the gas pumps. If he slowed down just a shade (high 20's) he would most likely sip fuel instead of gulp it.
Total get the Pavati overbuilt mentality. They're using 1/4 in thick sheets for the hull and tower. I totally get why those boats are on triple axle trailers.
