In the light of The new Seawind 1370 arrived on the market to great fanfare. As a result, we have received many technical questions surrounding the construction process of this new liveaboard cruising catamaran. As a matter of fact, It’s understandable that everyone would like to know how we build the most popular new catamarans of 2021! The first hulls for Seawind 1370 #1 is already in construction. Therefore now it’s time to take you on a deep dive into the first stage of construction.


At Seawind Catamarans, we require the production to achieve the highest standards, using advanced construction processes and techniques, using only the highest quality materials and equipment. Furthermore, all of that is supervised by a true expert in the field – our Lamination Manager, Danny Searle.  The overall aim is to achieve the most consistent, high-quality, and efficient level of construction while minimizing wastage and environmental impact. Through this craftmanship we can deliver a first-class and luxurious 45’ cruising catamaran.

Similarly to many composite catamarans, the Seawind 1370 has major components which include hulls, deck, liner, and large parts like consoles — all are moulded from fiberglass.

Prior building the moulds, we created a master plug. The plug shown above is built to razor-sharp accuracy to produce a precise set of mould tools. From those moulds we can build perfect repeat parts for years to come.
