Moth on Foils: 32.2 knots (37.03 mph)

Is there any chance a Moth could be homemade from aluminum, and still be light enough to perform? Not for competing, just for fun. If so, are there plans available

Moths dominate Bloody Mary

Tuesday January 10th 2012, Author: Andy Rice, Location: United Kingdom
The Bloody Mary Pursuit Race was run for the 39th time this weekend at Queen Mary Sailing Club started by double Olympic Gold Medallist and club member Sarah Ayton. This was also the second leg of the SailJuice Global Warm-Up series. The race again took place in decent conditions with a good breeze and double digit temperatures following six days of gale force winds which meant the day before we were still putting the club back together again. This attracted 302 entries in 63 classes from 104 clubs from as far afield as Rock.

While the inclination is to use maximum flap, decreasing this as you get airborne, McDougall says the secret in marginal conditions is not to use very much flap and to keep it in that same position until you are airborne. Another inclination – to move body weight aft to help the foil’s lift – is also a no-no. “In fact, you probably go forward to keep the boat level, so it is tracking through the water correctly,” he says. “The old bow-up way is wrong. Basically you need nice hull speed and the foils are just lifting and you gradually come up and accelerate and you can time your pumps correctly just to get it up. Usually if you need more than one pump you probably won’t stay on the foils anyway.”

McDougall reckons you need to be going around 6.5 knots* to get airborne and it is possible in less than this with a full-on oouch, and then to sail very low, but he emphasises: “You shouldn’t need a massive amount of pumping. We can design these boats so that you can pop it up very easily without all the macho stuff. Yes, you have to point down to do it, which is a loss upwind but if you get on the foils it is a major.”

* So that means the boat takes off at 7.5mph-pretty good!

Excerpt from Scuttlebutt Europe today:

Rob Greenhalgh Takes The 40th Bloody Mary

Jason Belben crossed the line first but a missed mark hands victory to Greenhalgh

Following a record advance entry the gusting winds and chilly conditions excited more to venture out and a monster 340 boats took to the water. Officially the Virtual Rigger 40th Bloody Mary Pursuit was the largest race since 2000.

The crowds were entertained by great close up sailing action with the start line to the west and a gybe mark set close in shore on the east. The action was accompanied by BBC commentator Malcolm McKeag and included various interviews through out the day including a chat with Andy Rice, organiser of the GJW SailJuice Winter Series, of which this event was the fourth leg.

Sixty different dinghy classes entered and the largest fleet with 31 boats were the Merlin Rockets, followed closely by 30 Toppers and 28 Laser Radials. There were 12 classes with 8 or more entries all qualifying for a class prize.

The Winner of the Bloody Mary was Rob Greenhalgh from Stokes Bay Sailing Club in an International Moth. He walked away with a £250 voucher from event sponsor Virtual Rigger and Vodka and tomato juice for a well deserved 'Bloody Mary' from Thymelords catering team. He was followed home by Andrew Friend of Queen Mary and Peter Barton of Royal Lymington also in Moths. In 4th were Rick Peacock and Nick Murray in a 49er, in 5th was Stuart Jones in a Contender and in 6th was Rob Watson and John Clifton in an RS800.
The Toppers led off in a gusty Force 4 which progressively dropped to a Force 3. This helped the Toppers keep the lead for over an hour until the chasing Laser 4.7, Solo and Miracles overtook them. The faster boats enjoyed the fact that an easterly wind direction provided lots of reaches where they could fly their kites. With an hour to go, the wind was back up to a Force 4 which also favoured the later starters. Despite having put back the Moth start by 6 minutes from last year (and by 33 minutes from 2008), with 20 mins to go the Moth sailed by Jason Belben took the lead. In the final stages there were 11 classes fighting it out for the top positions.
The drama of the day was not over since a successful protest against Jason Belben saw his result disqualified.

Burling Wins 2013 Australian Moth Champs

New Zealand's Peter Burling has won the 2013 Australian Moth Championships Regatta held over the last week at the Wangi RSL Sailing Club, north of Sydney in New South Wales, Australia.

Racing in the 15 race series staged over six days, Burling dominated the fleet winning no less than ten of those races. He only finished outside the top six in just one race and concluded the regatta 14 points clear of second place-getter Scott Babbage. Reigning world champion in the Moth Joshua McKnight finished third.

While not a World Championship Regatta the fleet in Wangi, which totalled nearly 70 boats, was entirely world class and included; Joshua McKnight (2012 Moth World Champion, AUS), Tom Slingsby (2012 Olympic Laser Champion, AUS), Nathan Outteridge (2012 Olympic 49er Champion helm, AUS) and Iain Jensen (2012 Olympic 49er Champion crew, AUS) to name a few.

Top ten final results:
1. Pete Burling, 21 points
2. Scott Babbage, 35
