D-section tubes?

Does anyone have an option on D-section tubes? I am looking at project now where more internal space is needed. I am considering D-section tubes but canít see that they are used much. Is there a good reason for this?

Not entirely sure how you'd create a D-section tube - inflatable ones anyway. You'd need some serious internal structure to hold the D shape.

Most D shape tubes I've seen are solid - foam, ali etc - they provide the buoyancy/stability of inflatable tubes, but don't provide the same shock absorption.

My thoughts exactly.

No such thing as a truly square bubble.

I think the blade runner rib uses a similar arrangment.

Ah, I see, an inflatable fender type arrangement rather than traditional tubes.

I can see how that would work to get the shape, and also the deck space advantages. Mmmmm, wheres that old Phantom hull I saw laying around

Nice tubes...
How would a d-section compare in price to a normal tube?
