JOWI Sailboat Support Systems |
|
JOWI Sailboat Support Systems are adjustable, folding, steel Sailboat Cradles.
Proven the best & absolutely safest method of hull support for building,
transporting and storing sailboats. JOWI cradles come in six (6) models which
quickly adjust to fit any sailboat up to 20 tons displacement. These cradles are
specified and used by The United States Coast Guard Academy, Navies, top
sailboat builders such as Eric Goetz Custom Sailboats, Carroll Marine, and
Concordia Yachts, boat yards and yacht clubs worldwide.
Excellence in Support System Design & Construction:
1. Pressure treated wood. Will not rot.
2. Large diameter screws with wing nuts for quick easy vertical adjustment.
3. All fasteners zinc plated to resist corrosion.
4. Pressure treated keel board. Will not rot.
5. Cross members positioned so cradle may be lifted with slings or forks without
additional blocking.
6. Unique vertical assemblies quickly adjust inward to fit varying hull widths.
Also will fold flat for storage.
7. Extra heavy rectangular steel tube frame for more rigidity.

CHOOSING THE PROPER JOWI CRADLE |
JOWI Cradles come in six sizes. See individual cradle specification below. The
right cradle for your boat is generally determined by displacement. The cradle
can be adjusted to any hull shape and the vertical tubes sized for any draft.
(At one time or another, JOWI Cradles have been fitted to most modern sailboats;
so many of the dimensions are already on file. With this information, we can
help with the exact vertical support tube lengths for your boat - just tell us manufacturer,
model, keel configuration, beam etc.)
There are a few exceptions, such as some of the light weight, high performance
sport boats that can have an exceptionally deep draft in relation to
displacement and length. An example for picking the correct cradle: Say your
boat displaces 7,200 lbs., is 29’ long with a 4’-6" draft, the Model One is the
obvious choice as it has a capacity to 10,000 lbs. and 30’. Exception: say your
7,200 lb. boat is 40’ long with a 7’-4" draft - clearly the Model One frame is
too short, so we may suggest a Model 1.5 or Model 2. If you have questions,
e-mail us or give us a call.

SUPPORTING SAILBOATS |
A boat is a major investment, and when it comes time
to store a boat, it should be done with an eye toward protecting that
investment. No method of boat storage will support the hull as well as the
water; making any other means a compromise - to some degree.
Keels can generally support up to 95% of a boat’s displacement. The sides and
bottoms of most modern laminated hulls should never be required to accept
concentrated loads, i.e. a large amount of weight on a few pads. If possible,
supporting means used against the hull should be located at bulkheads and/or
stringers.
Never store a boat with the mast stepped unless the masthead is secured to the
ground to prevent the boat from tipping. The side area of a mast is more than
sufficient to turn a boat over in high winds. Boat stands, on the surface at
least, seem to be an economical means for storing a boat. The problem with
stands is that each one transfers its load to a separate patch of ground and the
ground is not a stable platform. When the ground cycles from wet to dry, freeze
to thaw, etc., it moves in relation to itself. If stands are not constantly
adjusted to compensate for this, they can loosen and spill the boat. Typically,
in today’s tightly packed commercial boatyards, this has meant that whole rows
of boats go over like dominos.
There have been several instances of this, even in yards staffed with people
having years of boat handling experience - just think about the responsibility
involved in storing your boat at home on boat stands. For these reasons, among
others, some insurance companies refuse to cover boats or yards that use stands
for boat storage. Before putting your boat on stands, it might be wise to check
with your agent or boat yard.
Cross stands off the list of options and that leaves you with cradles, both wood
and steel. The problem with wood cradles, besides rotting and thereby losing
strength, is that they will eventually sag and permanently warp. Once this has
happened, the cradle will no longer fit the hull for which it was built and,
therefore, can no longer properly support it. Serious damage can be caused by an
ill-fitting cradle.
This leaves us with the proven best and safest means of storing a boat - the
JOWI ADJUSTABLE, FOLDING, STEEL CRADLE. The boat rests on a sturdy steel tube
frame with integral vertical steel tubes and screw/pads that can be adjusted to
the correct angle and pressure for the hull. When the earth moves, the
boat and steel frame move as one with it. Every time your boat is cradled it will fit
perfectly. JOWI cradles also fold flat when not in use, to conserve space. And,
surprisingly, considering its many advantages, a JOWI adjustable, folding, steel
cradle is competitive with wood in cost.

MANUFACTURER’S EXPERIENCE |
Gaskins Designs, Inc. (GDI), the builder of JOWI Cradles, built the first JOWI
steel cradle in 1975 and has built thousands to essentially the same design
since then. All of the folks working with GDI are experienced craftsmen and avid
boaters.
