[Alberg30] More on Tanks

[Gordon LACO]

Hi Roger and gang...

Rigid plumbing is not used much because it copes so poorly with vibration.
It is possible to build in lengths of tube that facilitate movement, but the
added connections increase the likelihood of gas or liquid leaks... and can
double the cost of an installation.

To return to the inflatable issue... I was considering laying one in the
water tank forward as the built in tank makes a very good bed for an
inflatable.  I chose not to do it mostly because I discovered that what
looked like a footbath in the liner under my cabin sole was in reality a
holding tank without the lid.  I have the lid now and will use that.
