Flex Tape

Price Range: Under $30
Flex Tape is a highly flexible rubberized adhesive tape specifically designed to create a completely watertight seal over structural cracks or major leaks.
Why it's Onboard
We honestly consider a massive roll of Flex Tape to be an essential emergency tool on the boat. Unlike generic emergency tapes that can degrade and fail over time, we have found that this thick, rubberized material holds up well in marine environments.

Real-world Verdict
It’s hard to express how invaluable Flex Tape was during boats first ocean crossing from Cape Town to Europe. Days from land in the early hours of the morning, the starboard hull window started peeling off, allowing seawater to come pouring in every time a wave washed up. It was far too rough and dangerous to go outside, so Trent taped the window from the inside using the Flex Tape he’d bought along; it instantly halted the delamination and held the window in place for almost a year - longer than the factory installation lasted!
