Danish Yachts is to launch SeaStrider, a groundbreaking new range of high-speed passenger vessels that will be the first SWATH (small waterplane area twin hull) vessels to be built from carbon fibre.
The first boat under construction will be used for carrying service personnel and cargo to offshore wind farms, and for transit between the wind towers. The design has already been tank-tested to significant wave heights, permitting operation in almost all weather conditions, while maintaining safety and comfort. The purpose of the craft is to carry initially the construction teams, and then the maintenance and emergency repair teams to and from the offshore windmill turbine farms efficiently, safely and in total comfort. The twin-hull configuration provides increased lateral stability.
SeaStrider is easy to manoeuvre in high winds using precision controls to ensure safe placement of the turbine maintenance teams onto the wind tower dock at the base of the turbine. In addition for passenger and crew safety of transfer to the platform, the vessel is to be fitted with the base for use of a gyro transfer gangway on the transom.
This version is designed to an overall length of 25 metres with a beam of 10.6 metres, providing ample space for 24 passengers and five crew over a range of around 500 nautical miles. The design has a clear bridge area with good all-round vision, boasts comfortable seating and dining areas for passengers, at the same time providing comfortable sleeping quarters in three single and one double cabin. SeaStrider is fitted with specially designed brackets for a single-point lift, providing a "one wire" lift either on land or on a larger platform at sea.
Once ashore, SeaStrider can be placed on a flat surface, without the need for any supports or a cradle. The lightweight carbon fibre build maximises fuel efficiency, and with less requirement for fuel capacity, this allows more room for passengers and cargo. It also guarantees an extremely strong vessel at a reduced weight, ensuring minimum impact when mooring up at the wind tower.
