I have decided to build a catamaran houseboat since I have been looking for years to find just the right boat having come close a few times, however, the price has alway's been out of reach. Therefore, I decided to build what I could not afford to buy.

I started by building a plywood mold. I have had some experience in building fiberglass boats in the past but nothing of this scale, however the only real difference is that's its larger. One of my major concerns in planning its design was making certain that if caught in bad weather that its hull design would be very seaworthy.

Now that lamination is completed I am considering to either sell or rent the mold in order to help reduce some of the invested cost. The next step is to start joining the two hulls together and then build the superstructure on top of the 32x80 ft flat deck.

The boat will be powered with twin 405hp Cummins engines, interior layout will be pretty much a cross between a home and a typical motor yacht. Which I guess pretty much duplicates what most luxury houseboats look like.

Construction is thus far on budget, hoping to complete it for $300,000.00 with an anticipated launch date sometime this coming May.

This is one of the most fun projects I have ever attempted.

Yours truly, Warren Wagner

Warren, what a wonderful project and a major undertaking. I can see that you have planned the whole thing out well and the twin Cummings should push this baby just great.

Do keep us updated with the progress as there are many folks here that are considering building a boat, or that are actually currently involved in building a boat.

Lastly, hopefully some of our readers and visitors will share and post comments about their catamaran houseboat building experiences and tips.

Looking forward to seeing you project come to fruition.

Fyi, I'm planning a 3BR, 2B HOUSE-boat, if you know what I mean, to be built in 2017 in Central America.

Essentially, MV MAYAN PRINCESS will be a townhouse (that was originally designed for a narrow city lot) on a big/flat deck (26x60 foot), supported by a herd of 55gal plastic barrels & powered by a Cummins 4BT diesel, driving a BIG prop.

BEST WISHES on your houseboat.

yours, tex

I would love to see the progress!

I have nothing but well wishes for you, and I am glad to hear that you are taking the bull by the horns and building your Catamaran Houseboat and not caving in and paying those high costs that the boat building industry are charging..!

Not only that you will be getting exactly what you want and not someone elses dreams...

Good luck, and keep us informed with your progress ...
