Request Pre-Charter InspectionAbout ALTA
Alta is a 43.89-metre aluminium motor yacht built by Palmer Johnson in 2004 and refitted in 2021, registered in the Cayman Islands. Her exterior design was handled by Palmer Johnson and her interiors by Patricia Andrews. Twin Caterpillar engines provide a cruising speed of 13.5 knots and a range of 4,500 nautical miles, making her capable of extended passages across both the Mediterranean and the Caribbean.
She accommodates 12 guests in 5 cabins with a crew of 9, operating across a broad charter territory that takes in the French Riviera, Amalfi Coast, Sardinia, Corsica, Croatia, and Montenegro in the Mediterranean, and Antigua, Bahamas, Saint Martin, St Barts, and the Virgin Islands in the Caribbean. Alta suits an active group of up to 12 — families, mixed groups, or those planning itineraries across multiple regions in a single season. She is less suited to those seeking the latest construction or interior design, given her 2004 build year, or to guests for whom cabin count is a priority.
The 2021 refit maintained her in current operating condition, and the aluminium construction by Palmer Johnson — a builder known for performance-oriented hulls — gives her a lighter displacement than comparable steel vessels of the same length. A sun deck, gym, deck jacuzzi, swim platform, exterior bar, BBQ, and at-anchor stabilisers are among the amenities fitted.
The water sports inventory aboard Alta is notably varied: a waterslide, ten e-bikes, twin three-seat Yamaha waverunners, Seabobs, inflatable kayaks, paddleboards, kneeboard, surfboard, wakeboard, and water skis. The inflatable jet ski dock extends utility at anchor. For a charter yacht that prioritises activity and range, Alta offers a well-rounded proposition with the credentials to handle varied itineraries.
The provisional rating is based on available public data, reflecting acceptable standards across safety documentation, maintenance records, and operational protocols.
