RE: M_Boats: M17 Cockpit drain and water level

Thanks Bob, I will look into this check valve. I assume a check valve/ball valve shutoff combination would also work? Also, the earlier boat has a single central drain and no access. I had considered adding drains with strainers in each corner and some sort of access port, if not a complete opening locker in this space for access to the drain lines and so on.
