Delta Marine’s Katya, launched last year and delivered ahead of schedule to her owners, has enjoyed an active charter career in her debut year. Designers Jean-Claude Canestrelli and Delta Design Group have certainly delivered a rich mix of dark veneers and stonework that give the yacht an elegant air throughout.There are toys aplenty for guests, including two jet-RIBs, two PWCs and kayaks, towables and waterskis. Big windows open up the full-width master suite, and below there are four guest suites, one of which boasts a double, a single and a pullman berth. She has a top speed of 15½ knots and cruises at 12½ knots.
