M.Y. Silver Sonnet

Classic twin screw Silver Ormidale

Built in Rosneath in 1953 for delivery in 1954 Silver Sonnet is a true gentleman’s motor yacht. Designed by John Bain and constructed by James Silver of mahogany on oak with a teak superstructure she was designed for a family with crew. Two berths with toilet and galley lie in the bow with the galley astern on their quarters with ample space for food preparation and storage. Steps lead aft into the wheelhouse with dining area and good seating for six passengers. Further steps lead aft and in to the cabin area with storage and shelving as well as heads and basins on the starboard side opposite the two double guest cabins comprising twin bunk berths. The owners suite occupies the whole of the aft area with an ensuite head and shower. As was common at the time there is a double and a single berth in the aft suite. The single could be converted into a seating area.

Below decks are twin wing fuel tanks each holding 300 litres with water tanks holding 250 litres each (x 2). A 7 kw 50 hz Supersilent AC diesel generator (new 1999) is in an enclosed GRP housing. Also fitted in 1999 are two automatic bilge pumps to complement the manual bilge system. Currently there is no holding tank but there is plenty of room to fit one below the laundry room which is equipped with a washer and dryer.

With approximately 5ft of head room there is provision for a vice, work bench and tool box in situ.

A Perkins diesel boiler with an immersion system supplies hot water to the showers and to the radiators for the central heating. Water tank capacity is 600 litres.

The Electrical system consists of 2 x banks of 24 volt batteries supplying engine starting and auxiliary equipment plus a 12v system for the generator. Shore power connections allow a float charging system for the 24volt and 12 volt supplies. Ring main installed throughout the vessel in 1999. The brightwork was also rechromed in 1999. The radar and navionics were reviewed 8 years ago.

This is a serious cruising boat with elegant lines and light, airy accommodation. Davits hold a traditional tender while dining on deck is facilitated by a teak table with folding chairs and a top hinged benach box situated to the rear of the wheelhouse.

According to Lloyds register of yachts in 1980 Silver Sonnet, previously named Caledon, Nimble II, Lynara, Silver Bay and originally also Silver Sonnet, belonged to a Mr Lawrence W. Robson and Baroness Robson of Kiddington. At that time she was berthed in Lymington. While the Lloyds registration has lapsed the MCA registrations official number is 185764 and the call sign is MBXH.

The present owner has owned the boat since 2002 during which time he has continued to maintain her with a great deal of planking having been carried out in 2016 by Ken Dwan and co at Eel Pie Island. In my opinion the interior which is very original and has lovely features including a set of three taps in the galley (the third is for seawater) is in need of some TLC hence the price.
