Inspection and replacement requires the boat to be out
of the water.
14.6 Storage and Lifting
In most cases, the reason for storage is winter lay up. A
competent boat yard should prepare your boat for winter
storage. If you are removing your boat from the water for
another reason, use the information in this section as a
basic guideline. Following the procedures in this section
will help to extend the life of your boat and its equipment
and simplifies re-commencing in the spring.
Indoor storage is beneficial if you are storing your boat in
a climate that produces ice and snow. However, the stor-
age building should be adequately ventilated, not tightly
closed. Ventilation, both around and throughout the boat,
is very important.
If you use outdoor storage facilities, cover your boat with
a canvas cover with provisions for ventilation to keep the
boat from “sweating.” Building a frame over the boat to
support the canvas will allow the passage of air around
the boat. The frame should be a few inches wider than
the boat so the canvas will clear the rails.
Before preparing your boat for winter storage, check the
condition of the boat and its systems and equipment.
Note any repairs needed. The need for other repairs may
become apparent during winterization. Make arrange-
ments to have the repairs completed.
14.6.1 Disassemble the Rigging
The rigging should be disassembled as per the manu-
facturer’s instructions noted in the OEM manual (reverse
the assembly instructions). Once disassembled, the sails
should be stored dry and free of salt, folded but without
wrinkles. The mast and boom should be stored dry or
covered with sufficient supports to minimize any deflec-
tion. The jib furler assembly should be stored near the
other rigging with the center supported to protect the luff
extrusion (long center rod).
14.6.2 Lifting Your Boat
1.
2.
3. Following are guidelines which will help prevent damage
to your boat as it is being lifted.
Never hoist the boat with a greater than normal accu-
mulation of water in the bilge. Fuel and water tanks
should be empty.
Place slings where indicated by the Sling stickers on
the gunwale (Fig. 14.3). Proper location of the slings
is critical. Lifting at locations other than designated
by the Sling stickers may cause damage to the boat.
The labeled locations are optimal for balanced lift with
the structural integrity for the full distributed weight.
Damage caused by improperly placed straps is not
covered by the limited warranty.
Use flat, wide slings made of belting and spreader bars
long enough to keep pressure off the gunwale. Do not
use cable slings. Pressure by the slings on the gun-
wale can cause severe gelcoat crazing or more serious
hull damage.
The spreader bar at each sling should be as long as the
distance across the widest point the sling surrounds.
Weight should be primarily distributed along the keel. If
a marine railway or platform is used, locate and adjust
the blocking to distribute the weight over several areas
at the intersection of stringers and bulkheads. The
bunks and/or blocks should match deadrise angle and
provide adequate support and stability.
When lifting the boat, keep the bow higher than the
stern so the exhaust lines can drain. This will keep
water from running forward through the manifold and
into the engine itself where the water can become
trapped.
NOTE: Keep the bow higher than the stern every time the boat
is lifted. Do not lift the stern to change a propeller. Doing so
can cause water to enter the engine. Engine failure is possible
if water enters the engine cylinders. This water can cause
hydrolock and bend the piston rods. Even a small amount of
water can cause rust or other damage.
14.6.3 Preparing for Storage
Clean, scrub, and sponge the hull and deck as soon as
the boat is pulled from the water and is still in the sling.
Cleaning marine growth from the hull is easier when it
is still wet.
Clean the inside of all hull openings, thru hull fittings,
and screens. Inspect the hull and underwater gear
