Building Plans for Bulkheads on a Pontoon Houseboat

Building Plans for Bulkheads on a Pontoon Houseboat

Looking for building plans for bulkheads on a large pontoon houseboat? Here are a few of the drawings I made for the pontoons.

If anyone wants to follow these plans, any size boat from 24 to 120 feet can be had. Just remember that for every 12-15 feet of length over the 80 foot, you must increase the diameter of the pontoon 1 inch.

I am using 44 inch dia. for 80 feet. 100 foot would need 45 inch diameter and so on. On the other hand a 20-24 foot pontoon can use 36 inch diameters.. Also, for safety's sake, keep the maximum beam to 18 feet. Try putting a baseball bat into a coke bottle.

In most marinas, you will have to use two berths to pull into, they average 20 feet in width for the two. NOW this boat, including the pontoons is ALL WOOD.

The one thing I would strongly suggest is to buy and read TWICE, a book on fiberglassing over wood. If your fiber glassing is done right, your boat will last a life time, and be strong and durable. That's it for now, please look at the plans and enjoy, Bill

Well Bill, a big thanks are in order for sharing your building plans for the pontoon houseboat bulkheads.

You're definitely right Bill about spending some time reading and learning about "fiberglassing a wood boat". I have put some links below to help out with some books, videos, and dvds available.

Videos & Technical Books on Fiberglass Boat Building, Repair and Maintenance

To see some instructional Fiberglass Houseboat Building and Repairing Video & DVD's available.

Keep us posted with the building progress, and don't forget to take some pictures :)

Lastly, hopefully some of our readers will share and post comments about their pontoon houseboat building experiences. Feel free to use the "Click here to post comments." link found at the bottom of this page.

Thanks again for sharing, IAN from all-about-houseboats

Building 80' houseboat
by: Leo George William Smith

I'm interested in speaking with anyone who is planning to build or has built an 80 foot or larger lake houseboat. Right now I'm planning 20' x 80' solar-powered, two-story with an upper deck. Modern looking with mostly tinted glass. Four bedrooms four bathrooms, large kitchen Autopilot etc.

I'm looking for advice and to discuss advantages disadvantages

Ocean Drift or otherwise.
by: Bill V

Please, anyone wanting to use a houseboat in the ocean, DO NOT USE PONTOONS !!!! The ocean swell action on the two pontoons will tear them from the flooring, and leave you swimming for your life.

Any houseboat on a rough body of water, ocean, very large lakes and waterways, should look into a prow/bow (pointed) style full hull. It can be flat bottom or semi-V. These are commonly called displacement hulls. Thank You, Bill

I'm building a 24 x 90 ocean going houseboat on twin 6x8 oval pontoons with twin Detroit diesels.

It will have solar, wind, and diesel generator backup for power, rooftop veggies, rainwater collection, aquaculture fish farm, plan on living off-grid drifting with ocean currents motoring only to move out of harms way.

Houseboat Construction Materials?
by: Robert

What materials did you select for your pontoons, and what process did you use to build them. I have so many question how you built them. Amazing!

Outstanding job
by: Burpee

I am very much at the beginning stages of houseboat building. Your project is very ambitious, and I am interested in seeing more pictures of your progress along the way.
