Corp Foam
Posted on Monday, September 20th, 2010 at 10:36 amIs air-filled PVC Pipe better than Polyurethane Foam filled-PVC for Raft Boat? If no, how to integrate it?
I would like to build a raft by using pipe from the local store, I am half-american living in North-Africa (My Father is in American Engineer Corp in WW2, but I live by my mother no).
I have to load 800 kg of material as Gillnet! (sorry my budget don't permit to build a highly integrated boat and I will work in 70 cm water deep at 22°C at 300 meter from the beach). Don't be care for the security lool.
So what for Diameter?
What for contruction?
What for suitable colors?
How work the chemie and physic of Polyurethan?
Any serious advice (please avoid the style I have a friend that made a raft with condomnes as recycling), actually I am against condommne.
Best Regards

PVC pipe is a very bad choice for building any boat. It will degrade in sunlight and get more and more brittle. Eventually it will crack, leak or completely fail. Structurally, it is not intended to carry the loads that will be imposed by a raft design. Making a PVC raft is a big mistake. You would be better off making a solid frame from hardwood beams (no plywood) and using galvanized metal brackets and fasteners. For very cheap construction of a float for calm waters, some surplus PVC 50 gallon drums, filled with floation foam might work, but for goodness sake don't take the thing in the ocean.
