They told us we need to go this fast and weigh this much.
It wasn't a lot of guesswork. Maintenance and repair concerns
contributed to the selection of Demaree's tubes, too. They're
manufactured from a 30-oz. fabric coated with vulcanized
neoprene. Each RIB has two tubes, which connect at the bow.
Each tube has five air compartments and five valves.
Demaree Inflatable's owner, Dave Demaree, said that the
dual-tube arrangement speeds installment and replacement.
He estimated that it takes about 20 minutes to change
out a set. He also said that using twin tubes eliminates
having to replace the entire collar if just a portion
of it gets damaged.
Neoprene collars are less likely to suffer damage than
urethane ones, added Demaree. "They have about twice
the life of urethane, and the coating doesn't bleed out
of them."
And, neoprene tubes can be rolled up more compactly than
urethane collars, he said. Each tube fits into a 3'x2'x2'
box.
