O - 1 GENERAL INFORMATION
DO NOT use the weather covers for outdoor
winter storage. The weight of the snow or
heavy rain can cause severe damage to the
material or top structure. Refer to O-7 - Winter
Storage in this manual for more information.
Weather covers for the cockpit areas are available
on all Four Winns models. A bimini top and camper
is standard on the 338 Vista® models. Four Winns
covers are designed and intended to provide protec-
tion of the cockpit seating areas.
Four Winns utilizes 100% acrylic-type material for
most of its canvas. During the manufacturing of the
weather covers, the smallest possible needle and
highest quality UV stabilized, bonded polyester
thread is used in the stitching.
Four Winns is utilizing snaps for the canvas. The snap
sockets are a standard type. To unsnap, gently lift on
Remove snaps one at a time to prevent
damage. DO NOT rip off or pull the weather
cover as a whole; acrylic material will tear at
Never use any form of open ﬂame cooking
device in any area fully enclosed or near
weather covers. This material is ﬂammable.
O - 2 GENERAL CANVAS INSTALLATION
The weather cover is water repellent but not water
proof. During a hard rain, you may notice a light mist
permeating through a weather cover. This is normal.
If the seams leak, they can be sprayed with Scotch-
For safety and ease, it is recommended that two
or more people are available to install or remove
guard or similar type water repellent or a seam
sealing compound can be applied. Keep objects from
contacting the inside of the cover. Leakage may occur
at point of contact.
Ideally, canvas should be installed while the boat
is in the slip or moored securely.
Weather covers must be installed “snug” to prevent
sags. The material relies on swelling to seal itself.
If too taut or overly tight, the material will not seal
and may tear.
Be sure to observe all safety precautions to
prevent the build-up of Carbon Monoxide - an
invisible, odorless gas while the boat is running or
Store canvas pieces ﬂat, or if necessary, rolled;
do not fold.
Periodically check weather covers for
accumulation of water. Damage to the bow
assemblies may otherwise result. Make sure
cover is snug to avoid puddling of water.
Valances, visor and/or camper top must be
installed ﬁrst; all other pieces attach to these
After use, the top canvas should be rolled up into the
boot (supplied) and secured.
Partially zip zippers until all sides of a canvas
piece are in position.
Support poles are adjustable; a button-release lets
you slide the inner and outer tube to longer or
shorter settings for a snug ﬁt.
NEVER fold or store a wet weather cover. This
can lead to mildew or shrinkage. Roll rather
than fold the enclosure curtains. Sharp folds
increase the chance of cracking the clear vinyl.
Unsnap canvas by lifting at the button to prevent
damage; do not pull/yank.
