I just bought an early laser ('70's). It has a bung plug at the stern next to the rudder and one in the cockpit. For a boat of this vintage under what conditions should these be in or out?
The one in the stern should be IN; otherwise, your hull will fill up The one in the cockpit can be left out once it gets (quite) windy and a lot of water splashes into the cockpit. But under gentle conditions, most people will 'stopper up'.
the stern one should always be in... it's a sailboat, not a submarine. The one in the cockpit is there to drain the cockpit (duh) and is compatible with the autobailer system. I'd say spend the 50 bucks and get the autobailer.
