Typically, a non-pounding hull that rides smoothly through rough seas comes at the price of stability at rest. But thanks to the genius stabilising ballast technology that runs along the keel line, it’s not a problem.
As the boat comes to rest, the ballast tank fills and steadies the boat. It then drains as the boat starts to move forward and empties in less than 5 seconds. Simple. The result is maximum stability at rest, which provides more comfort for you and your crew and allows you to move around the cockpit safely.
In rough conditions the Surtees Shut Off Gate can be sealed to retain the ballast water, making the boat heavier, to give you a much smoother non-pounding ride and extra stability.
For every litre of water there is approximately 1kg of stability ballast in each Surtees boat. The ballast tank capacity varies according to the hull size, from 180 litres on a 495 up to 530 litres on a 750. So whichever Surtees model you get, that’s a lot of ballast making a huge difference to your boat stability.
