Morrelli & Melvin have designed Gunboat luxury sailing catamarans blend racing performance with the the finest level of comfort and amenties.

In 2001 Morrelli & Melvin designed a pair of 62' performance-oriented catamarans for clients Clint Clemens and Peter Johnstone. These two Morrelli & Melvin 62's were built by Harvey Yachts in Cape Town , South Africa .

These boats turned out so well that eventually Peter Johnstone formed a company called GUNBOAT to produce these designs. Two more 62's were built by Jaz Marine in Cape Town .

The next several clients desired more interior volume and amenities so the original Morrelli & Melvin 62' design was lengthened to 66' and branded the GUNBOAT 66. Morrelli & Melvin refined the structures, rigs, and layouts in order to optimize this design.

Morrelli & Melvin also designed a 48' high performance cruising catamaran for GUNBOAT. These 48's have proven to be a very popular and capable design, nearly equaling the stellar performance of the 62's.

In 2007, Morrelli & Melvin embarked on a 90' design for a repeat Morrelli & Melvin 62 owner.   This design was constructed at the GUNBOAT yard in Cape Town and was launched in April 2010.  Sea trials were completed in the US at the end of 2010.
