1980 Alden Skye

St. Petersburg FL, US




The Skye 51 was commissioned by the John G. Alden Company, designed by the naval architects Kaufman & Ladd of Annapolis and built by Mao Ta Shipyard in Taiwan. Eighteen Skye 51’s were built under the direct supervision of Alden and are highly sought after by world cruisers. S/v Cielo Grande is Hull number 1.

The design was for a “blue water performance cruising yacht” easily handled by a couple and intended for world voyaging. As such, The Skye 51 has been designed, engineered, and built to quality standards comparable with the finest yachts in the world. Few performance cruising designs built today have the exceptional strength, classic styling and beautiful Burma teak woodwork that the Skye 51 offers.

Cielo Grande is an exemplary Yacht with a spacious sleek open deck, large safe cockpit and wide side decks that make for comfortable and safe cruising.

The interior arrangement provides 2 separate en-suite cabins – one aft cabin with a double berth, private shower and head, and one forward cabin with a twin bunk over a double berth, also with full head.

The spacious saloon provides 2 secure pilot berths, a U shaped settee and large dining table.

Just aft of the Saloon are the updated galley and navigation station.

Aft of the captain’s cabin lies a large walk in engine room with the renowned 85 Hp Perkins 4.236 Marine Diesel.

The V-berth can serve as a crew cabin or storage for tools and sails.

Her cutter, ketch-rig with Harken furling jib and Facnor behind the mast furling on the mizzen allow her to easily be handled under any condition. The jib and mizzen sails are operated from the cockpit and when sailing under jib and jigger, she can be safely sailed single handed.

Cielo Grande is a world voyaging yacht that has completed two circumnavigations. The current owners spent the last two years cruising the Sea of Cortez, Pacific Mexico, Costa Rica and Panama before transiting the Panama Canal and sailing her to St. Petersburg, Florida. She underwent a major retrofit starting in 2015 to include: electrical, plumbing, refrigeration, stove, navigation, 2 autopilots, led lights, engine rebuild, water maker, roller furling, stainless work, canvas, solar, and removal of the teak deck.

She is well equipped to continue cruising the world off the grid in style, safety and comfort.
