That boat isn't a commuter.fpjeepy05 wrote: ↑Fri Aug 23, 2019 5:30 pm a friend just sent me this listing... https://miami.craigslist.org/pbc/boa/d/ ... 41647.html

That's a big job but there is another solution, something I have done for other builders: fora fee, I can calculate the scantlings for an Atkins design. You get the plans from Atkins, I do the calculations.
Agreed. But it does get 13mpg
The problem is, there isn't an Atkins design I would like to build. I don't mind paying to get some help, but to make matters more complicated, I am leaning towards constructing from aluminum.
I like the fast launch 26. I was hoping to get similar numbers speed wise with a 30x5’ it sounds very possible if the fast launch can do it with 26x8’ I would like to have a smaller flat on the bottom with some deadrise to accompany it. Additionally I would like to have a walkthrough-cabin with an open bow instead of an express style. This will likely be difficult with the narrower beam. Likely necessitating the engine below the sole. Which will be tough.
I am looking at commuter boats because those are the only ones with the fuel economy I am looking for, but I actually plan to use it for fishing.fallguy1000 wrote: ↑Sun Aug 25, 2019 11:28 am Sadly all boats are tradeoffs.
There is no luxury in the economy cruiser. This is why the statement of requirements is so essential.
For example, the boat pictured would not be suitable for most commuter boats. The pax would be soaked, and the vessel at risk in 6 footers.
Diesel inboards are often touted as the ideal, but they are expensive and more difficult to build.
The Nina 22 is probably my favorite for a commuter; although the downside is speed. The Nina 22 would put that skiff picture to shame. I don't know the fuel economy, but I would guess 6-8mpg at the right throttle/speed tradeoff.
And the Nina would be ultra-quiet, too. Pax could have a conversation in low tones in a low head cuddy and the helm could probably be managed inside with a remote, but I could be wrong.
Not sure if you could do a hybrid ally and foam build, but ally would be a fast hull and then you would build light for any cabin/seating area.
