Thanks again guys for some very good information. Now that I know all this,
I feel better armed to apply a remedy - after I contact the boat
manufacturer.

Hmmmm... repair a cracked tube without damaging the boat any more.

There is a company called "Insituform" http://www.insituform.com/
whose business it is to repair cracked underground pipes for utilities
etc.
Obviously, they fix large piping, but one never knows how small a tubing
they may have worked on recently.

The process is something along the lines of inserting a flexible, resin
impregnated, tube of woven material into the target pipe;

In the Insituform® process, a resin-impregnated Insituform® tube is
installed into a damaged sewer. This process results in a seamless,
jointless "pipe-within-a-pipe" with a smooth, continuous inner surface
which
usually increases flow capacity. We typically complete installations in a
single day, using robotic methods to restore active connections from
within
the line.

I have no earthly idea if they have any process that can help you, but I'd
surely contact them to see if they can steer you in the right direction.
That's their business, .....fixing cracked piping. Your problem may be
the
size of your piping and the costs of their services.
Doesn't hurt to ask.

Again thanks for help guys. All are worth investigating.
Now, suppose the channel is damaged how would suggest it be repaired and
I
surely wouldn't want the guy that sold me the boat do it. He has
damaged
everything they worked on since I bought the boat new last June. What
recourse does someone in this situation has?

To Clams Canino, RG, Gene Kearns and Lawrence James, thanks for
suggestions.
The scope seems the way to go though who would have ten to fifteen
foot
scope to view the channel? Does a plumber really one of those?
