JOHN E. POWELL 37 FT MOTOR YACHT 1956 - Sold

In MARY ISLAY, John E. Powell - Aeromarine’s highly proficient in-house yacht designer who would subsequently become better known as an alloy spar maker - perfected a highly attractive and purposeful fusion of workboat type with yacht styling and construction standards. Dubbed a “fishing yacht” on launch, this teak wonder achieves a whole lot in her overall length, with well thought-out space above and below for cruising and pottering by family and friends. Sensibly and economically powered by a trusty Gardner 4LW, and given more than just deserts professionally in current ownership, MARY ISLAY is a very special love affair waiting to happen.

2016-2020: MAJOR REFIT & OTHER WORKS: TRADITIONAL SHIPWRIGHT SERVICES, POOLE
Having been laid-up on a spring tide mooring at St Helier from 2006, she was shipped on a 40ft platform unit from Jersey to Poole in August 2016. Towed to Traditional Shipwright Services, Poole, she was hauled into their shed and engine removed. She was given a through clean and most fittings, shaft, tube and rudder assembly removed. Over the next two years, steady work was done around regular customer operations.

The main hull structural work included a new oak inner stern knee. Other work included replacing a section port and starboard of the main aft deck stringer/shelf at the fo'c'sle step. Sections of the main cabin and wheelhouse roofs were replaced and new epoxied cloth covers fitted. The engine room roof and mast step beam were replaced with new. Oak fenders each side replaced and new brass strip added.

New stainless steel fuel tanks and pipework were fitted and some engine room insulation replaced. The engine wiring loom, instrument panel, switchboards and all electrical wiring replaced and new LED lighting fitted to original brass fittings. All seacocks removed, re-seated, new bolts, new toilet pipework, sink drains, bilge pump hoses and new pumps fitted. A new exhaust pipe, watertrap, u-bend and outlet were also fitted.

Surveyor inspected all hull planking and fastenings and except for 5 bronze screws, which were replaced, all found in good order. Hull and houses stripped back to bare wood, houses epoxy coated and re-varnished. Hull re-stoppered, primed, undercoated, antifouled and topsides finished. About 100 bronze deck screws were removed, holes re-countersunk, refitted and re-plugged. RNLI Scuppers were removed, overhauled and refitted. The mast had new internal aerial & electric cables fitted.

In 2019 the mast was re-varnished and new SS standing rigging fitted. In 2020 a new starboard beaching leg was made and fitted.

MARY ISLAY was launched at Emsworth on Thursday 21st March 1957 for aviator, merchant banker and eventual airline industry executive Sir Giles Guthrie, Bt., and named after his mother. He had been an RAF fighter pilot in WWII and would become a board member of British European Airways (BEA) and chairman and chief executive British Overseas Airways Corporation (BOAC), predecessors of British Airways. Guthrie moored MARY ISLAY on the main channel moorings of the Hamble River off the Royal Southern YC and The Bugle pub. Yachting Monthly magazine covered her build and first year in Dec 1956 and March 1958, and she features on the cover of the August 1957 edition of Yachting World, and in their 1957 Annual. In 1962 Guthrie sold her when he became chairman of BOAC and she was then based on the Beaulieu River. Subsequent owners kept her in Northumberland, then on the River Thames at Datchet. She was fitted with beaching legs and davits at Cowes on her way to Jersey in 1986 to be based at St Aubin. MARY ISLAY's last Jersey owner purchased her in 1992, with her longest voyage being to the 'Brest 96 & Douarnenez traditional boat festivals. Regular shorter runs were mainly to local bays, Les Minquiers, and Île de Bréhat in Brittany.

Poole in Dorset is the traditional UK hub for the Channel Islands and it is not uncommon for Islands based yachts to be maintained and refitted there. MARY ISLAY became a regular client of Poole-based Traditional Shipwright Services where her wonderful lines and arrangement won many admirers. One of TSS's existing clients purchased MARY ISLAY while in for refit in 2022 and has used her for family pottering in Poole Harbour where she continues to be wintered indoors, and is professionally maintained by Traditional Shipwright Services.

John Everett Powell began his working life in 1937 as an apprentice boatbuilder at the brand new and impressive Sussex Yacht Works, Shoreham-on-Sea, where he was immediately recognised as a very bright spark and later encouraged by his drawing office friend Austin Farrar - who had worked with Robert Clark - into a career change to naval architecture that did him no harm. At this time Sussex Yacht Works was mostly involved in building Clark’s early designs, including the series-built Mystery Class, and winning offshore racers ERIVALE and JOHN DORY. Impressions would have been lasting.

During the Second World War, Powell followed Farrar into a British Admiralty research department led by Charles Currey that successfully developed netting torpedo protection for warships, including time spent on the Firth of Clyde where he may have first encountered his future collaborator, John Illingworth.

Post-War - after a period as naval architect back in Shoreham-by-Sea at the renamed Sussex Shipbuilding Company, to his own account (including building in his Kingston-by-Sea back garden a 30 foot sloop for himself), and with Robert Clark, Jack Laurent Giles (notably on the revolutionary Sussex Shipbuilding Co. built aluminium ocean racer GULVAIN), and four years as an assistant to Arthur Robb - between 1952 and 1958 ‘Johnny’ Power was yard manager and naval architect/ designer at John Illingworth’s Aeromarine yard at Emsworth. Here Powell’s design output included some famous contemporary small and ‘JOG’ ocean racers such as ARTICA II, BELMORE, MOUSE OF MALHAM, and WISTA.

During the 1948-1949 build of GULVAIN, along with Jack Rawlings - owner of both the boat and her builders - John Powell had taken out a patent on extruded aluminium alloy mast construction. Ten years later, Powell left Aeromarine to become a pioneer manufacturer of such spars as ‘Sparlight’, later John Powell Masts, eventually taken over by Proctor. His design role at Aeromarine was filled by Angus Primrose.

In his autobiography ‘The Malham Story’. John Illingworth speaks highly of John Powell’s abilities. He deserves to be better remembered. MARY ISLAY is a very fine testament.
