The three-bedroom house was originally part of the Waternish Estate and is on the market for offers over £435,000.It is within walking distance of the nearest village, Stein, along the shore, and has safe mooring for boats.The sun-trap house has two sitting rooms, a large kitchen, a family bathroom, and one of the bedrooms has an en suite bathroom.
The 18th Century building, which Donovan converted into a home in the 1970s, is on the shores of Loch Bay, on the Inner Hebridean island.
The setting is so tranquil and romantic that it was chosen for a wedding, and many couples have had honeymoons there after as it was used as a holiday let.
It has views across the loch to the islands of Islay and Mingay and the distant mountains of North Uist can be seen.
In 1971, Donovan had George Harrison and his wife Pattie Boyd to stay at his home in a sheltered bay on the Waternish peninsula surrounded by wildlife, which has a waterfall behind it.
Phiddy Robertson of Galbraith said: "This is a truly spectacular setting to enjoy a tranquil island lifestyle or to take advantage of the many opportunities for outdoor activities such as
walking, cycling, water sports, wildlife watching or wild swimming.
"The Boathouse has been modernised sympathetically, retaining all the character of a traditional building and making the most of the lovely outlooks."
