Stuart Cranston, representing Strangford Lough Yacht Club in Northern Ireland, was on the podium again with his Quarter Tonner, this time finishing second in Class Six at Cowes Week

The winner was Sam Laidlaw's 28-foot Quarter Tonner BLT, which, after a major and extensive refit, appears virtually unbeatable.

The 7-day series saw mixed conditions, ranging from 6 knots to 30 knots. Cranston's beautifully restored wooden 25-foot Quarter Tonner placed in all the podium positions among a top fleet of Quarter Tonners and similarly rated boats.

The crew for the regatta included Stuart Cranston (Strangford Lough YC), Mark Mansfield (Cork), Saul Vassallo (Malta), Colin McKenzie (Strangford Lough YC), Kristin Borg (Malta), and Chris Gracey (Northern Ireland).

Purple Haze, a David Thomas design, serves as the prototype for the Bolera Quarter Tonner, which is quite well known in Ireland. Rating considerably below the other Quarter Tonners, she was typically boat-for-boat ahead of the others at the finish, apart from Laidlaw's BLT.

About Quarter Tonners

The Quarter Ton Class is a sailing class of the International Offshore Rule racing the Quarter Ton Cup between 1967 and 1996 and from 2005 until today.

The class is sailed by smaller keelboats of similar size and is likely the world's most-produced keelboat class.

The Ton, Half, Quarter, etc. 'classes' were each given a 'length' and yacht designers had almost free rein to work the hull shapes and measurements to achieve the best speed for that nominal length.

The Ton Rules produced cranky and tender boats without actual downwind speed. Measurement points created weird, almost square hull shapes with longish overhangs.

They were challenging to sail optimally and lost value very quickly as any new wrinkle (e.g. 'bustles') to take advantage of the rule made older boats very quickly uncompetitive.

Although its heyday was 30 years ago, the boat class continues to make its presence felt by holding its own in terms of popularity against some fern race fleets.
