Boat Cover Vent Caps

Do Boat Covers Need To Be Vented? 

Absolutely, the answer is yes.  

The build up of moisture under a boat cover happens. 

Rain storms while boating are unavoidable and even if the boat has been left open to dry it will condensate moisture on the underneath side of the boat cover due to changes in temperature throughout the day.  

It’s important to dry out the inside as quickly as possible, and venting allows this moisture and heat to escape and dry quicker. 

We carry two styles of boat cover vent caps with screw-in installation. Both are not 'use alone' vents and should be used in conjunction with support poles. 

Position them inside your boat cover and over the top of your boat cover support poles.  

The support poles fit nicely in the molded receiver cups on the bottom side of these vents. 

This makes pushing up your boat cover a snap!

Boat Vent II

Boat Vent II has a design best suited for heavier duty applications.   

• Thicker materials do best with this vent
• Very simple screw nut on the backside
• Boat Vent II will require a sew in reinforcement in the cover.  Installed without reinforcement, it’s likely to rip through the cover over time.
• Size - 4.5"W x 4.5" D x 2.5" T

Boat Vent 3

**Not recommended for use with heavier materials that are 10 oz or higher with double sided acrylic coating such as Top Notch or Harbor Time. Boat Vent 3 may not work on these types of material since the heavier material may slip out of the teeth which could damage the boat cover.

Both Vents are made of tough UV stable plastic and no tools required.

Made in the USA
