Inflation of the BoatCapsule is maintained by a high-pressure fan that provides continuous airflow to keep the boat dry and prevent condensation. Air inside the bubble is completely exchanged with filtered outside air 3-6 times every hour - keeping the temperature inside consistent with the temperature outside and eliminating moisture that could condense on the boat. Bubble creates a cushion that protects the boat from impact damage, scratches, and falling objects. Easy to use and sets up in 7-10 minutes. Made with durable 16 mil PVC for hot and cold weatherability as well as blockage of damaging UV rays. Floor is made from 18 mil PVC that is mildew, abrasion and flame resistant, as well as impervious to oil, gas and coolant. Offered in 16' and 18' lengths, and in custom sizes to match your needs.
