For starters, on the Gunboat 62 ELVIS was Steve Cucchiaro (J/105 North American champion strategist), Cam Lewis, Jack Slattery, Mark Laura, Brian Thomas and Dru Slattery- all avid J/Boats sailors over the years having fun cat racing in the Caribbean.
Similarly, long-time J/105 and J/70 owner Chris and Carolyn Groobey were sailing the Gunboat 55 TOCCATA in the same class with Stu & Julia Johnstone aboard. Here’s a nice sailing video of her by ace Spanish photographer Jesus Renedo: https://vimeo.com/125166259.
Finally, Stu’s brother Peter J. was sailing the brand new Gunboat G4 TIMBALERO III (40 footer) and learned their limits of sailing a performance cruising foiling catamaran on the final day of Les Voiles de St Barth- check out the sailing video here: https://vimeo.com/125378004
