Type of boat stands to use
How to use screw boat stands
type of Marine boat stands (sail jack stands vs. motor vessel) is determined by the angle
between the hull and the stand center pipe. The threaded rod from the
top that enters the stand center pipe should do so at approximately a
90° angle to the vessel hull. For example, a motor vessel with a deep v
bow would use a pair of sailboat stands at the bow, with motor
at the stern.
Size: To determine the proper boat jack stands to use, you
first must realize the jack stands are to stabilize your vessel and the
keel blocking supports the vessel weight. A simple method would be to
take the draft of the vessel (in inches), add the height of the blocking
pile, and subtract about six inches. Base your decision on keeping a
minimum amount of thread exposed on the top for dry docking.
Number vessel hull supports
A minimum of four jack stands should be used with
powerboats and a minimum of five jack stands should be used with
sailboats. One exception: a full keel sailboat may not require a bow
stand. Use a pair of jack stands, one placed port and one placed
starboard, for approximately each 8 feet of the vessel's length. If you
are going to be stored in an extremely windy area or leaving a sailboat
mast stepped, extra vessel stand should be used in add to our
Liability: Because the performance and safety of vessel jacks stands
is dependent on the way they are used, the manufacturer assumes no
liability beyond the purchase price of the vessel stands.

How to Use jack stands For Dry Docking your boat using our stands
When ready to use Jack Stands you must choose an area to store
the vessel that offers hard, stable ground to prevent the sinking of keel
blocking and stand. Jack Stands should be placed outboard on the hull for stability.
The stand tops should have minimum thread exposed with the threaded rod
placed as close to per perpendicular as possible to the hull. To guarantee
the threaded rod being close to perpendicular, the boat stand base rear
legs are placed so they are parallel with the waterline. The boat stand
is placed square to the hull (not twisted fore or aft) with the boat
stand top on the flat of the hull for stability.
Bow and/or Stern: Most sailboats require a bow jack stand with a
V top to prevent the bow from dropping forward. The exception to the
rule might be a full keel sailboat that is not "bow heavy". Any
excessive overhang in the stern requires two additional stands port
and starboard on the after portion of the boat.
Safety Chains: When using safety chain for sailboat stand, the
port (or starboard whichever comes first) stand is placed in position
with the jack stand top snug against the hull. A 3/16" chain is
placed in the safety chain notch of this boat stand and the chain is
passed athwart-ship either before, after or under the keel to the
starboard, or opposite stand chain notch. The starboard boat stand
is placed in its approximate position but not snugged tight against the
hull at-first; the chain is pulled tight and placed in the starboard
Boat stand chain notch. Once snug in the chain notch, pull the starboard
boat jack stand outboard until the chain is snug. Tighten the boat stand top,
making sure the rear legs of both boat stand are parallel to the hull.
Use safety chains and repeat this procedure for all side sailboat stand
to prevent the boat stands from sliding up a boat's hull.
Keel Blocking: We always recommend a minimum of 2 blocking
piles placed on hard, stable ground to carry the boat's weight. Each
blocking pile consists of 3 blocks, i.e. two base blocks facing fore and
aft running parallel to each other, and one block placed across the two
base blocks for the keel to rest on. This method has proven to reduce
sinking of the blocks. For each blocking pile we suggest 2 of our B-8
(8"x8"x22") pine blocks for the base blocks and 1 of our B-6 (6"x6"x22")
pine blocks placed across the base blocks. Higher or lower blocking
piles can be used depending on how the boat drains, however, the lower
to the ground, the better. More blocking piles should be added as
necessary depending on the condition and length of the keel
Vessel jacks and blocks should be checked on a regular basis while
your vessel is being stored. Make sure the jack stands are snug against the hull and
the keel blocks are supporting the keel and not sinking into the ground. Also
check the blocks for rotting or splitting. Do not tie tarps to the Stands.
During windy conditions, check more frequently for proper vessel shoring and security of our
stand while they are stabilizing your vessel. When not in use, we
recommend lubricating the threaded rod section of our Tops (WD40 or axle
grease may be used) and storing in a cool dry place. Our nestable and
stackable vessel stand bases should be kept painted with rust preventative
paint. Moisture and salt creep up from the ground and corrosion may
start from the boat stand base bottom up. Replace any badly rusted boat
stand or rotted blocks, safety is jeopardized.
