Re: Pumps do not do what you think
I did the exact same math with my boat shortly after we bought it and discovered that the gunnel would be underwater in less than 17 minutes with a 1 1/2" hole.
I wanted to have an idea of how much time I would have to abandon ship in the event that was unable to keep up with a leak.
We have three rules;
No bleeding on the sails.
No slobbering on the charts.
