The Mariner Episode 7: Water Ballast System
In this episode I get to grips with 'Hellcat's' water ballast system. The system has six tanks- two forward tanks, two tanks under the side deck next to the shrouds and two under the deck next to the cockpit. In the engine bay a pump can be operated to move water through a network of pipes that draw in water from the sea and distribute it to any one of the tanks. This is a major performance component of the boat helping to give her an incredible max righting moment of 33,000kg/m. (The class max has since been reduced to 29,000 kg/m) As with so much of this boat I was working out the system literally as I was filming this series- I think you can literally see the cogs going round as I work problems out! www.spartanoceanracing.com Facebook www.facebook.com/spartanoceanracing/ Music: 'Bumblebee' YouTube Open Licence Video: Spartan R/T 2018
