I am looking for any suggestions for a material that can be used to
fill the void in a PVC or ABS tubing, if and when used as tubing for a
bimini or the like. What size would you recommend?

Some thoughts include: epoxy, liquid foam, (cement -concrete???).....

Also what about using braided cable as a sort of rebar in the tubing
before filling tubing void?

Also what about using 3/4 or 1 inch copper tubing for a bimini or
dodger (plumbing supplies) with same tech. as above.


Thanks in advance.

Quoted from www.capehorn.com. Yves Gelinas is the designer of the
CapeHorn self-steering system and this is the solution he came up with
for the dodger frame for his Alberg30 that he circumnavigated with.


"I wanted my dodger to whitstand a knockdown or a heavy sea falling
aboard. The solution I came up with was to replace the stainless steel
tubes of the frame with 2 inch dia. Dacron fire hose blown with air,
much like a bicycle tire : hit by a sea, it collapses and pops up again.
The ends of the tubes are capped with round PVC inserted into the tube
and held with 3 hose clips at each end. I purchased screw-on tire
valves, punched a hole near the end of the tube and screwed the valve in
place. I need to blow it up only once a season, and after 20 years, it
is still airtight."
