Flexible Tanks |

|
|
Nauta Flexible Tanks provide many advantages over rigid
tanks and have, therefore, become very popular with both yacht-builders
and boat-owners.
Each of these tanks uses an extremely rugged 840-denier nylon fabric,
coated on both sides with a neoprene/nitrile compound. Heavily lapped
seams are inside-reinforced with a "doubler" to provide
extra strength.
Flexible tanks
Because of their flexibility and the Nauta range of sizes, these
tanks can fit into almost any space, especially those odd-shaped
places that would otherwise be wasted.
Nauta tanks are very easy to work with. Several for water and holding
are available with fittings already installed. But Nauta's construction
allows custom placement of fittings to suit your particular requirements
and makes it simple to install them. The low cost of tanks and installation
appeals to everyone.
Flexible tank is unique in operation: as liquid is drawn out, the
tank "collapses." This not only eliminates the need for
venting of water tanks but also minimizes free-surfacing action
which dramatically reduces sloshing and its noise.

Dimensions (except on outboard
tanks) are for empty tanks; when tanks
|
are mounted horizontally and filled, these
|
|
dimensions
reduce by 10%15%. The filled
|
depth (highest to lowest point)
|
ranges from 12 to
16, depending on tank
|
|
size. Stated
capacities are given for optimum expanding conditions (a flexible
tank conforms to and is limited by the space
|
|
in which it is mounted).

Water tanks for Boats
These tanks are also popular among some sailors who use them as
ballast tanks, knowing that the contents can also be used for emergency
drinking water.
Our most popular application is also the easiest way to increase
or replace water capacity on boats whose tankage is inadequate or
deteriorated.
Nauta flexible water tanks use an exclusive Tedlar inside lining
to maintain a taste-free system: most PVC, fiberglass, other plastics
and metals contribute a distinct, unpleasant flavor to fresh water;
Tedlar does not. No venting is required for water tanks, only a
fill pipe and a simple draw line to head and/or galley pumps. 5-year
warranty coverage.
Holding
tanks
The more rigorously enforced laws against overboard discharge now
make non-compliance extremely costly. A Nauta flexible holding tank,
on the other hand, provides a relatively inexpensive Type III solution.
In addition, the Tedlar lining of these Nauta tanks prevents gas
permeation, thus stopping a major odor problem with many other holding
tanks.
Combined with a few other components, this solution is both legal
and far less costly than replumbing a vessel or installing a more
complex and expensive Type I or Type II system: it occupies less
space and requires no electrical power. The illustrated example
would allow those travelling into unrestricted waters to pump overboard.
1-year warranty coverage.
Diesel
tanks
Nauta Boat flexible diesel tanks can dramatically extend the range
of diesel-powered sail and motor yachts. They can deck or cockpit
mount to gravity feed (or be hand-pumped to) tankage belowdecks.
And, when empty, these flexible tanks can be rolled up and stowed!
Sport and commercial fisherman heading into offshore waters and
cruisers visiting remote ports (where refueling may be unavailable
or of suspect quality) will find these Nauta tanks an ideal, low
cost solution.
Nauta diesel tanks of 53 gallon capacity and larger are supplied
with adjustable hold-down straps with D-rings. Two N.P.T. brass
fittings (3/4"and 11/2") allow this system to connect
with conventional fuel-line piping. 1-year warranty coverage.
