Waterproof Hatch for RCLifeOn's RC Airboat

After having plenty of fun with RCLifeOn's Airboat I decided to try to come up with a more water proof hatch design which can be easily opened and fastened closed with split pins (Or a bent paperclip).

24/09/2018 - Finally got chance to test this out. The boats kept really dry (until the crash). The video is on my YouTube channel here:
