SIRONA was designed by Bill Tripp and built with composite construction methods in 1999 by Marten Yachts. She was meant for world cruising and performance, and easily reaches sailing speeds up to 20 knots. 
She has an overall length of 72 feet and a beam of 16.7 feet.  A custom designed lifting keel allows SIRONA to cruise waters or glide in an anchorage close to shore.  Designed with a low center of gravity, SIRONA is highly stable and lightweight, allowing for smaller sails, higher hull speed and lower loads, resulting in more time to enjoy the sailing.
The Tripp design includes a raised pilot saloon which allows for comfortable sailing in any weather.  The raised saloon features interior steering & lounging areas and excellent panoramic visibility.  The pilot house shelters the cockpit which is surrounded by dual coaming.   A twin headsail system provides the right sail angles at all wind speeds and allows SIRONA to reach her sailing potential without the need to change sails.  A fully battened mainsail sits in a "gull wing" boom enables ease of handling.
Stepping below from the pilot saloon to the lower saloon, there is a bar to to starboard,  a dining area to port and a forward galley. Two cabins (1 queen and 1 with two singles) and a guest head are forward and the master with private head is aft. Engine room sits amidships below the cockpit & pilothouse and a hydraulic transom door opens for storage.
Sirona completed a full refit in 2019 including repower main engine and generator, new Air Conditioning, New Water Maker, New Electronics, New Interior, New Teak Decks and davits set up to carry 13.5’ center console tender with 40 Knot top speed. Sirona is also set up with inflatable paddle boards, floating island, snorkel and fishing gear.
