Tips and Factors Regarding Your Pontoon Boat of Choice


1. Be considerate of the water

Are you going to use your pontoon boat on a small lake, a larger lake, or coastal waters? Each type of boat is designed for some particular environment. If your waters can be very rough at times, or you want to go for long distances, you’ll want a specific type of boat.

On the other hand, it’s not necessary for a boat that can handle strong waves if you’ll only be using it on a smaller, protected lake.

If the water is often calm, which is common in small lakes, it is alright for you to look for a small pontoon boat. For lakes and rivers with potentially large waves, you should consider boats in medium size at least.

Lastly, if the water is typically rough, you may want the pontoon boat length to be between 23 to 28 feet and width between 8.5 to 10 feet.

2. The width can be measured in different ways

Depending on the manufacturers, a pontoon boat’s width can be measured as the deck width or the tube width. You should focus more on the deck as they are the one providing space on your boat, while the tube is more about its power and performance.

3. Be careful with your garage door

You should know that the average garage door is usually 7 feet wide. If you want to use the garage, make sure your pontoon boat can fit through the entrance. It wouldn’t hurt to measure the length by yourself instead of just relying on given numbers. Meanwhile, the double doors can be 14 to 16 feet. wide–plenty for most boats.

4. Custom pontoons is also an option

Obviously, the best boat for you is the one designed on your demand. Try asking a boat designer for a custom-built boat. If it is possible, by careful measurements and consideration of your personal usage, you can have a perfect pontoon boat.
