Britain's most popular single handed catamaran
The Dart 15 is a fifteen foot, one-design catamaran which can be sailed by one or two crew with mainsail or mainsail and jib. It consistently has the largest entry of any single handed catamaran class in British National events. The boat can be trailered or transported on a car roof and can be easily rebuilt, ready to sail with no tools in under an hour. Take a look at our welcome page or contact your local Dart 15 sailing club to find out more.
Each year the Association organises a Summer Series, a Winter Series and two Nationals Championships for unarig or two-up and for Sport Mode (single handed with main, jib and trapeze).

TT at Grafham Water Sailing Club
Race Report(Posted on: 11th March 2026 at 18:47 pm)
The final TT event of the Winter Series was held at Grafham on Sunday the 8th March. Uncharacteristically, we managed to race five events in a row this winter without any postponements or rescheduling due to poor weather and all in light winds. This made organisation much easier for the new Winter Series coordinator. The overall winner had been decided at the previous event at Datchet, but 2nd, 3rd and 4th places were all still to play for.

TT at Datchet Sailing Club
Race Report(Posted on: 12th February 2026 at 17:56 pm)
The Dart 15 fleet returned once again to Datchet for this, their fourth Winter TT of the season. After a prolonged spell of grey, cold and wet weather, thirteen competitors arrived to mild and finally dry conditions. Winds were very light to start with but were forecast to build during the day. Aside from the weather, other talk over boat rigging was about the three competitors who had “upgraded” to newer boats and were trying them out for the first time today. Two of these boats have been given somewhat interesting names already by their new owners (both boats were previously un-named so no bad luck hopefully). So it was that “Hot Rats” and “Nice Pair” had their maiden voyages.

TT at Draycote Water Sailing Club
Race Report(Posted on: 12th January 2026 at 15:01 pm)
For the third event of the Dart 15 winter series, the first of 2026, the day started sunny and frosty but with a bleak wind of around 3 knots when people turned up and started to get boats ready. Special mention for the travellers from Shanklin and Marconi who made this event a 3-way club battle. It is quite an effort for all the travellers.

TT at Stewartby Water Sports Club
Race Report(Posted on: 18th November 2025 at 09:38 am)
In the interest of an easy life for me, I tried very hard to keep the entry numbers down to a minimum and started this process by introducing an error message in the on-line entry system, adding random unrelated paragraphs to the Sailing Instructions and arranging for a weather forecast of little or no wind and as much rain as possible. That’ll do it I thought. Despite my best efforts mind, the competitors didn’t seem to be phased by this with 25 entries on the books already. This wasn’t in my plan so I really needed to up my game or we risked having a highly competitive very well attended event. So, now to launch emergency plan B the day prior, announce a break-out of the dreaded Bluegreen Algae, a massive bloom more dangerous than a shark infestation, surely that will finally put folk off. But no, the competitors still came so the only option left was to lock the Club gates so no one could get in. Finally sorted I thought, but no, half a hour later some smarty pants managed to scale the fence and carry out an emergency gate opening, damn! So despite my very best efforts we were all on for big day’s racing.

Summer Series TT at Grafham Water Sailing Club
Race Report(Posted on: 22nd October 2025 at 18:33 pm)
In time honoured tradition, the Dart 15 fleet completed their 2025 Summer Traveller Series with their Inland Championships at Grafham Cat Open. It was great to see so many entries across various cat classes – around ninety boats in total split into fleets across two race courses. The Dart 15s were sharing their course with the mixed handicap fleet of mostly Dart 18s, Shearwaters and Catapults but with a separate start.

Summer Series Sport Nationals at Shanklin Sailing Club
Race Report(Posted on: 29th September 2025 at 17:03 pm)
Sponsored by Gurit, Spinlock and Fernhurst Books. Forty six boats entered the Dart 15 Sport Nationals at Shanklin with 25 local sailors taking part as well as 9 from North Devon Yacht Club. We had once again lured Nigel and Fiona Denchfield to the south east of the Isle of Wight with the promise of sunshine, flat water and a constant breeze. However we sent them out in a grey, cold F4 north-easterly in a bijoux fishing boat with a building sea state. The racing was incredibly close from start to finish with nobody dominating a single race, let alone the regatta. Seven different sailors won races and the champion wasn’t known until the scores got entered after the third day. Frequently the best course was to find a way to tack early to harness the best tides and those that turned right earliest usually prospered.
