Advice on lasers

Hello everybody,

today afternoon I've been installing an inspection port in my laser, because it's getting water through the mast step and I plan to make some repair work, following the instructions in other threads in this forum.

The port is already installed but I have to prove it with a nice capsize to check if it is correctly sealed.

I had never seen a laser inside and I got a big surprise: when I tried to have a look to the centreboard hole I realized I have two plastic barrels...
