Welcome Aboard to Gullsweep, the finest bird deterrent for boats

The GULLSWEEP® is made of materials that are resistant to the effects of salt water and sunlight. The arms are bright anodized aluminum. They may be cleaned with a damp cloth. An abrasive cleaner should not be used. All other metal parts are stainless steel. The bearing pin should be kept clean, as an accumulation of salt is very abrasive. Wiping it with an oily cloth will accomplish this, and will provide a little lubrication. Wash out the bearing hole occasionally with fresh water. Tests have been made at wind velocities in excess of 60 miles per hour with no adverse effects.

However, we recommend that the GULLSWEEP® should be removed and stored away when winds are in excess of 35 mph as birds will not be roosting in such a wind, and the high rotation rate will not improve the life of the GULLSWEEP®.

ASSEMBLY: This GULLSWEEP® has been pre-assembled for your convenience. All you need to do is follow the directions for the mounting parts (GS-4 Deck Mount) or the other non-permanent mounting accessories. When placing your GULLSWEEP® onto the center mounting pin, fold the arms out and, remember to take the vanes out of the storage position (Figure 7A), or the unit will not work. The vanes snap off to the left side of the support rod when looking down over the center hub (See Figure 7). The vanes will thus be on opposite sides from each other (See Figure 6).

MOUNTING: The GULLSWEEP® can be mounted on the canopy forward deck or stern deck, as shown in Fig. 1 or Fig. 2. The bearing pin should always be vertical to the water for optimum results (Fig. 4 & 6). If tilted it may not work as well in a light breeze. Where there are searchlights, etc., on the forward part of the canopy, or on a very large canopy, it is preferable to mount the GULLSWEEP® toward the stern, as in Fig. 3. Since a gull generally lands into the wind, this position is most effective. If additional clearance is needed, the arms may be bent as in Fig. 4. When mounting the permanent base block on wood or fiberglass holes should be drilled first, using a 1/8” or #30 drill. (See enclosed pamphlet for additional mounting options.)

When Storing GULLSWEEP® lift vane up against top spring and rotate over rod (Figure 7A). Vanes will be parallel to each other when rods can be folded up thus taking any strain off the vanes hinge point. Your GULLSWEEP® is shipped with vanes in storage position (see Fig. 7A)
