#MarineWildlife - The Guardian reports that fishing is expected to be banned near Rockall after the recent discovery of a rare ocean floor gas vent and new species of shellfish.

The 'cold seep' methane vent found by Scotland-based marine scientists last year is only the third of its kind to be found in this region of the Atlantic Ocean - and apparently has a 'chemosynthetic' relationship with two species of deep-water clam, and the polychaete worms they contain, that are new to science.

Also found was a frilled shark, described as a 'living fossil' for existing as a species for at least 90 million years. Such sharks are seldom seen north of the tropics.

In the wake of these findings, the International Convention on the Exploration of the Seas has recommended a ban on fishing activity at the site and its surrounds.

Rockall - which adventurer Nick Hancock is attempting to occupy for a world record attempt - is a tiny rocky islet north-east of Donegal, almost halfway between Ireland and Iceland in the North Atlantic. It has long been the subject of territorial dispute, with Ireland, the UK, Iceland and Denmark all staking a claim.

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.
