The below the waterline should not be an issue...
You could always 'practice' in the harbor... (just kidding
On boats I have seen there is usually a seacock for the exit.
If you have an electric
macerator then crank it on and make sure you hear noise
as the stuff goes out.. You can hear the pitch
change as it empties the tank.
If you have a manual pump then the same thing, except that you can even feel how the manual pump is now pumping nothing... (at least that has been my experience).
The only unpleasent thing could be the smell if the pumping is from a head
area, and the head
has not been maintained. I try to flush with some white vinegar and even do some empty flushes on the head to insure that the holding tank
gets a nice rinse out....
Best of luck, and look forward to hearing a success story.
BTW, at least you have a great excuse for a good sail, so get a six pack and enjoy!
(and make sure your guests use the head BEFORE you pump out... then restrict them...
