ISO 'Wide Beam Canal' Boat Builders in US.

as per @fallguy i will be doing a new thread with the process etc

 

How does the weight compare to steel or aluminum?

 

@gonzo
that's a very good question
Both HDPE and galvanized steel are common materials for pipes and pipe fittings. They also have two similarities: they are both durable and anti-corrosion. These make them popular options for water delivery, such as irrigation. however, HDPE is more lightweight since it is still plastic.

there are a few companies that currently make HDPE boats these are made for police boats etc (there is a company called
which make HDPE work boat we took that concept for our barge obviously

 

However, steel pipes need less supports than PVC or HDPE for the same installation. For plumbing that may not be a major issue. For boat construction it is. It surprises me that as the designer/builder you can't answer the question of how much the boat weighs.

 

@gonzo
apologies I misread your question I thought you said how it compares to what i was trying to explain
the simple answer is obviously steel is a lot heavier than HDPE which can be a positive and a negative in regard to floating problems

 

Steel is denser. My question is about the weight of the hull compared to a steel construction.

 

the weight of the whole boat without an engine etc was 6tonne

 

Does that include all the interior, hardware, tankage, etc.?

 

unfortunately, not this just includes it as a shell as we have not as of yet fully fitted this out

 

That is quite heavy. How do you install an inboard engine and align it? Also, how do you deal with heat in engineroom from propulsion engine, generators, etc.?

 

Someone built an hdpe mini jet up here. Eventually tore the bottom off it and the drive got swapped over to an aluminum hull with a uhmw bottom.

Great idea for a barge or landing craft or kayak.

Let me phrase it another way, I utilize boats that have constant contact with gravel bottoms. I'm in the process of updating my fleet. As a consumer there is 0 percent chance I'd consider an hdpe hull. But it will definitely be used to clad high wear areas.

 

I agree that it makes great chafe protection.
