#SailInSpace - An idea once proposed by astronomer Carl Sagan for a ship that could 'sail' through outer space may become a reality after a crowdfunding campaign spearheaded by Bill Nye 'the Science Guy'.

As the Washington Post reports, the LightSail concept reached its Kickstarter goal of $200,000 in just 24 hours, and marks the first step towards what Nye hopes to be a prototype for an affordable 'people's spacecraft'.

LightSail uses fabric 'solar sails' that, rather than catching wind like they would on Earth's oceans, would catch photons from the sun's rays to slowly but surely propel tiny spacecraft through space.

While the concept is a long way from being a solution for human space travel, it could open up space exploration to hobbyists and students around the world and usher in a new era of discovery.

#SolarSail - Ahead of the start of this year's Route du Rhum offshore race, UK Sailmakers gave a special preview of their state-of-the-art solar mainsail that will get its first proper sea trial on board the IMOCA 50 yacht Martinique Challenge.

As previously reported on Afloat.ie, the revolutionary new sail uses the French-designed SolarCloth System, whereby photovoltaic cells are woven into the fabric in a flexible film – allowing whatever boat hoisting it to generate power from the sun, even without direct sunlight.

The SolarCloth System has been specially designed for offshore races such as the Route du Rhum, so it will be interesting to see how the technology performs when the Martinique Challenge sets sail from Saint-Malo tomorrow with a fleet that includes an Open 60 piloted by the legendary Sir Robin Knox-Johnston.

The Half Ton Class was created by the Offshore Racing Council for boats within the racing band not exceeding 22'-0". The ORC decided that the rule should "....permit the development of seaworthy offshore racing yachts...The Council will endeavour to protect the majority of the existing IOR fleet from rapid obsolescence caused by ....developments which produce increased performance without corresponding changes in ratings..."

When first introduced the IOR rule was perfectly adequate for rating boats in existence at that time. However yacht designers naturally examined the rule to seize upon any advantage they could find, the most noticeable of which has been a reduction in displacement and a return to fractional rigs.

After 1993, when the IOR Mk.III rule reached it termination due to lack of people building new boats, the rule was replaced by the CHS (Channel) Handicap system which in turn developed into the IRC system now used.

The IRC handicap system operates by a secret formula which tries to develop boats which are 'Cruising type' of relatively heavy boats with good internal accommodation. It tends to penalise boats with excessive stability or excessive sail area.

Competitions

The most significant events for the Half Ton Class has been the annual Half Ton Cup which was sailed under the IOR rules until 1993. More recently this has been replaced with the Half Ton Classics Cup. The venue of the event moved from continent to continent with over-representation on French or British ports. In later years the event is held biennially. Initially, it was proposed to hold events in Ireland, Britain and France by rotation. However, it was the Belgians who took the ball and ran with it. The Class is now managed from Belgium.
