Crack open one of the orange emergency boat repair kits, in less than five minutes you will have mixed the resin and hardener and wetted the reinforcement fabric ready to fix to the damaged area. In these types of emergency and nerve wreaking situation the last thing you should have to worry about is having to care about the resin hardener ratio or how many resin you need to prepare for that size reinforcement. 

CompositePatch is an error-proof repair system: the resin is yellow, the hardener is blue: as long as the mix is not green, it mean the mix is not ready. One mixed and the fibre impregnated, just cut open the plastic and apply the repair patch.  

You don't need to be inside, even in the worst condition of wind, waves, rain and cold weather you can keep that giant dagger board on the deck and fix it there. 90% of the resin strength is obtained only hours after the gel in any weather condition. After few hours, you know the fiberglass boat repair is structural and sound and you can get in the race again.
