At the A&R shipyard in Germany, the successful principle of SWATH boats was further developed in 2013: The SWASH principle allows sea-going, smaller and more economical boats.
SWATH and SWASH are interesting technologies that allow a vessel to sail much more calmly in high waves. A stable and calm position of the ship is especially important for pilot boarding.
Earlier this year ABP announced an investment of around £9 million to build nine new pilot boats. These vessels were ordered from Goodchild Marine Services Limited and are being built in Norfolk along with much of the supply chain coming from East Anglian suppliers.
When a vessel navigates in confined waters, such as in a harbour or narrow channel, it is well known among experienced pilots that the ship handling is greatly affected by the hydrodynamic forces and moments acting between ship and bank or sidewall of the channel.
