The Manufacturer of






Working with Multihull Technologies, Inc. for over 20 years.

Nigel Irens Design - Here is a taste of some of the projects we have been involved in over recent years. As you will notice they are a fairly mixed bag from 60' racing trimarans displacing 5.3 tonnes to a live-aboard 40' cruising gaff cutter which weighs in at 20 tonnes!

We feel that there is nonetheless a common link between them in that they are all boats designed for very specific purposes for owners who are very exacting in their requirements.

There is no shortage of mainstream production boats available in the world but if you are looking for something original and different then we would like to hear from you.

Problems can not be solved with the same mindset that created them - It is a capital mistake to theorize before one has the correct data.
