Does your boat have a method to lock your hatch-boards in place? It is all too easy to find that your boat has been hit with a big gust of wind and is now heeling over so far that water is washing the windows and pouring over the coaming. If your hatch is wide open, you risk swamping the cockpit and even sinking your boat while water pours over the coaming and through the open hatch.
An easy way to solve this is with locks on your hatch-boards.
Putting barrel bolt locks on the upper corners of your hatch-boards will allow you to easily put the hatch-boards in and then simply lock them in place. Easy because you have drilled holes in the hatch molding into which your barrel bolts fit.
I have done this on my two lower hatch-boards. And, yes, I do lock them in place if the weather is getting rough.
I am about ready to put them in right now!!!
