If you are confused about what a SWATH vessel is, then you have come to the right place. John Kecsmar from Ad Hoc Marine Designs joined us in 4C Crow's Nest and explained very eloquently what is meant by 'SWATH', that is to say, 'Small Waterplane Area Twin Hull. John is a naval architect with many years of industry experience and is well-known for his expertise in SWATH designs.

John talked about how the SWATH design was developed and has since proven itself in the offshore wind market, achieving safe transfers in high seas. He also explained other advantages of the configuration as well as debunking some of the myths surrounding the vessels.

Given their track record in offshore wind, it is perhaps surprising that the number of SWATH vessels working in the sector remains relatively low. Currently, there are 21 CTVs and 1 SOV in operation. But two more SWATH SOVs are underway. The two WindKeeper vessels in build at the Cemre yard in Turkey for GC Rieber Shipping are a SWATH design.
