FAQs about PortVisors™
Strong UV-resistant Lexan
PortVisors™ are made from
seaworthy materials. They
shield ports from sun and rain.
(Model 14-RE)
Can I install PortVisors™ myself?
Yes. Installation is simple and only takes a few minutes. They are installed with 3M VHB
tape (provided) or marine grade silicone as an alternative. No drilling, cutting, or special
tools are required. Instructions are provided with each part.
Are they strong enough for extended marine use?
Definitely. Their seaworthy materials are extremely strong and will not rust or corrode.
Will PortVisors™ snag lines or shins?
No. Since they only stick out from the cabin side less than 3", they won't get in the way.
The angled design prevents snagged lines or gear. Their tough materials resist wear and
tear, as well as damage from deck activities.
Are they difficult to keep ship-shape?
Definitely not. They are engineered for years of worry-free use. Just rinse with fresh
water. Avoid using any abrasive or ammonia based cleaners which can fog the surface
and damage the UV-resistant coating.
