Of course not! Whats a manual bilge pump gunna do on a 1000 foot cruise ship? Or 1000 foot oli tanker?
Or on the bounty when it was leaking 800 gallons per minute... 48,000 gallons per hour?
Well the only had 2 electrical pumps 150 (max) each, they could have used 5 manual gusher 30 to have 150 gpm extra.. Looks like 16 people on board only 1-2 dealing with pumps..
