Are PortVisors™ really an aphrodisiac?
Hmmm ... they do increase comfort and relaxation in the cabin ... and they do prevent
sudden mad dashes at night to close portholes when a rain comes up ... but we don't
think they compare to the usually accepted romantic strategies.

Will PortVisors™ work on all boats?
No. There are a few situations when they cannot be attached or may be less effective:
• When portholes are recessed or surrounded by trimwork, there may not be enough
flat area for the PortVisor™ flange to make a secure and watertight seal.
• The greater the cabin side and porthole angle, the less effective PortVisors™ will be.
Here are photographs of a few examples.
