Maia 24 Question for Jacques

Post by Jeff » Fri Jun 07, 2019 7:10 am

This question came into our email system last evening: "Hello, I am looking and comparing different displacement type of small boats for cruising and fishing use. I wondered what is the fuel capacity for Maia 24 since it is not listed on the site? Was there a limit to how much the engine and gear should weight as well?" Jeff

A unique little boat.

Good questions, too.

The ppi is not in the study plans and a useful measure for such a question. I am guessing the ppi is somewhere inbthe neighborhood of 450-550. And that means for every 500 pounds you add; the boat gets an inch lower than her designed lines.

And you calculate the allowed displacement to water by taking the displacement less the hull weight which is 4200 less 3100, or a generous 1100 pounds for persons motors gear and fuel before you take her down below design.

If any of my interpretations are wrong; corrections welcome. I am mostly pointing out; the boat has generous numbers for a trailerable craft.

This is one of Evan Gatehouse design. If I remember well, the tank is 20 gallons which is enough to run hundreds of miles.

The boat is really set up for longer cruising, so extra weight (extra fuel) will not hurt it. A standard rectangular tank under the cockpit sole is shown on the plans that holds 13 gallons. With a 8-9.9 HP 4 stroke outboard that is enough for about 20-25 hour of operation at a "fast cruise" - minimum about 5 knots or 100-125 nautical miles. With a 10 HP diesel it would be enough for nearly 190 mile range (~0.35 gal/hr)

If you went with a custom welded aluminum tank shaped to fit the space it would hold much more.

Additional shallow fuel tanks can be added under the cabin sole as well. But because it is shallow, you will not likely find much in the way of stock rectangular tanks that are a good fit.

You can also stow a few jerry jugs under the sidedecks in the cockpit.

Suggested outboard is between 8 and 10 HP and extra long (25") shaft.
Suggested inboard is up to about 16 HP. Small 1 and 2 cylinder diesels don't vary much in weight and the boat will be fine with them.
