Johnstone had a pretty good idea of what he was looking for: a big, powerful, no-holds-barred catamaran built of the latest, lightest materials, with ample accommodations, and manageable by a shorthanded crew. Ultimately, he formed his own company to produce such a vessel. When the seagoing Johnstones finally set sail for the Caribbean, they did so on the M&M-designed, South African-built Gunboat 62 Tribe. After returning from his 15-month cruise, Johnstone rolled up his sleeves and got back to boatbuilding in earnest. The Gunboat 48 is the company's second model in production, and the next will be-yikes-an 80-footer, currently under construction.
