If you want to learn how to build an unsinkable houseboat, you should first learn about the different kinds of hulls you could have.
Pros: The pontoon boat is known for being the most reliable and essentially unsinkable. The inflated pontoons are designed so that they are divided into sections. Because of this, if one of the sections becomes punctured, the rest of the pontoon will keep it afloat. Pontoon boats also offer great fuel efficiency and the possibility for propane appliances without the risk of being exposed to heavy fumes.
Cons: Pontoon boats don't do well in choppy water. When approaching a large wave, for example, the structure of these boats allow them to easily be swamped with water. Pontoon boats also rock more in the wake of other boats as the waves pass under and lift both sides of the boat at different times.
Pros: Mono-hull boats typically provide more storage space than pontoon boats. They also allow for extra living space inside the hull with bunks. Mono-hull houseboats offer bigger engine options, which make for higher speeds. They are also much better in rough waters than the pontoon boats and can handle a harsh storm or big waves well.
Cons: Mono-hull boats are much more expensive to maintain than the pontoon boats and also weigh a lot more. There is also a safety hazard with the propane fumes building up inside the hull.
Pros: Houseboats with catamaran hulls glide very smoothly over the water. They also have great steering and are stable in harsh conditions. Catamaran houseboats are usually made of fiberglass, which is extremely easy to maintain, not to mention their engines get great gas mileage.
Cons: Catamarans tend to be less popular than mono-hulls and pontoons because they are more difficult and more expensive to transport. They are also not the best fishing boat because lines can get caught between the two hulls.
Sinking houseboats are not common, but you want to make sure you build a hull that will last wherever you go. When choosing your houseboat, consider where you'll be taking it and what you'll be using it for. Also, make a price comparison chart to help you with houseboat financing. No matter what your houseboat needs are, there is sure to be a hull design that works for you.
