Kevlar, Water Absorption reported

An interesting observation by some friends who recently hauled there 65 foot catamaran vessel and found significant water absorption by the Kevlar material utilized in some of the construction

While we were out, we decided to do our bottom painting. It took 12 days of sanding … TWELVE days!!! Before getting to the bottom layer and finding micro-bubbles in many places, but mostly where we had lain Kevlar: water had gotten into and behind the Kevlar, needed to scrape and dry and prime, etc…. It was an ugly job. Kevlar is NOT a good thing to have below water: it does not absorb the resin but will absorb water! While fixing the scrape from the reef encounter, JP removed entire strips of waterlogged Kevlar
