WARNING! You must mount to solid deck construction using specified fasteners
in all mounting holes and nuts, washers or backing plates to achieve correct
maximum working load to avoid a failure leading to an accident.
Determine if deck is strong enough for mounting the SnubbAir. Make sure all four fasteners are
through bolted using washers or backing plates and nuts. Cored decks must have solid inserts
such as G-10 plates sized to distribute the load. Tapped holes will not work for installing SnubbAir.
Install SnubbAir using sealant in holes. Use supplied washers and nuts or
suitable alternatives. 3
Tip: Put slight bevel at top of hole to allow sealant
to mass around upper part of hole.
Use the mounting template located on page 7 to mark the deck. Note: The studs on the SnubbAir
are integral to the base and are not removable. There are sleeves extending below the base and
these are a larger diameter than the 6 mm threaded studs. Drill holes for 8 mm bosses. See
dimension below.
Drill 8.5 mm or 11/32” holes.
8 mm (5/16”)
6 mm threads
Planning Installation - Deck Strength
Installing SnubbAir

Line up bosses on the underside of the adapter with the sockets inside the top of the drum. Use
your fingers to press the retaining ring into the groove. Start at one end and work around the ring
until it is completely seated in the groove.

Periodically inspect SnubbAir and fasteners for wear, corrosion, and loosening. Tighten or replace
as necessary.
Every time you rinse the deck, flush the bearings and pawls with fresh water as shown on next
page. Make a solution of detergent and water and periodically squirt it in the slot between the drum
and the center hub. Rotate the drum. Rinse with fresh water while rotating the drum. See next page
for illustrations of flushing points.
IMPORTANT! Do not remove drum to
service SnubbAir. Balls will be lost.
Leave assembled and flush as directed.
The SnubAir provides line-holding power much like a ratchet except much more. It is perfect for
spinnaker trimming. With a couple wraps of sheet on the drum, the trimmer can hold upwards of
500 lbs with just thirty pounds of holding power on the tail. The sheet easily flips off the drum for
a gybe.
Do not remove this ring
and lift drum!
