    The Multi70 Musandam/Oman Sail is still on record pace, Class 40 Stella Nova has retired with structural concerns.

    An extract from the following article:

    http://roundbritainandireland.rorc.org/newsblogsphotos/press-releases/307-records-set-to-tumble.html

    Day Two: PM Update

    Musandam - Oman Sail reached Out Stack, the rock north of Muckle Flugga and the most northerly part of the course, just before 1500 BST 12th August.

    The MOD 70, skippered by Sidney Gavignet, has about 46 hours to complete the remaining 1098 miles to set a new world record. Musandam - Oman Sail has averaged an astonishing 24 knots on a screaming reach up to the top of the course and needs to average the same, or better, on the way back down. It seems that the wind gods are with them as the new breeze is from the North West and came in just as the trimaran turned for home. It looks like a reach all the way down the west coast of Scotland and Ireland and maybe, just maybe, Musandam - Oman Sail can beat the 2011 record set by Banque Populaire 5, which is twice as long as Musandam - Oman Sail.

    Now a few miles south of St Catharines - Broad reaching I think, but their speed seems to have dropped a lot in the last hour or so and the last few miles will be to windward. Less than two hours left if they are going to get the record .....

    It's coming down to the wire the RORC's latest tweet from 5 minutes ago:

    #‎rorcsrbi‬ Musandam-Oman Sail are 4.4 miles off the finish line at the Royal Yacht Squadron, Cowes with 28 minutes left on the clock to beat the world record - we're all on the edge of our seats!

    update.

    17 knots and 1.3 nm to go acoording to the tracker.

    The tracker shows that they have finished but the counter hasn't stopped on the website as yet. Not sure if they have come in under the record time as yet.

    A pretty amazing effort it's strange but the delay at the beginning and the changing of the course direction provided a near perfect weather window for record breaking. It looks like the Monohull course record will be easily improved too.

    It's amazing to me the amount of work those lifting foils in the amas are doing. When you watch the video it seems like a pretty violent part of the boat to be. That they made it around at full throttle is a real credit to the engineers. Also, though their lap was less than 20 minutes faster than BP's, it must have felt like they were going 100 knots in comparison. Half the length at the same speed! Sounds like fun.

    Doug probably has the exact numbers but they lift about 75% of the boats weight and the MOD70's are optimized for their use. They are actually a pretty hopeless boat to sail without them as they don't have enough volume in the bow to resist nose diving. One of the teams actually in the Krys Ocean Race transat (I think it was Oman Sail?) chose to transfer the foil between the cases manually when one broke and insert it upside down, hard work as the foil weighs 100kgs.

    Corley,you're right about 75-80%. I had an article saved on the computer that died last week. Whats particularly interesting is that an all out foiler is designed with 75-80% on the main foils and the rest on a rudder foil or foils. The pitch control on a MOD 70 is thru ama volume + mainhull volume(to the extent there is any).
    Since these foils are "C" foils there is no altitude control except reducing speed.
    On the ORMA 60's there were crashes as a result of flying the main hull and accidentally flying the ama, when that happens there is no pitch control. It seems those lessons were learned well since they seem to be able to push the 70's w/o crashes,

    First VO65 over the line is Abu Dhabi Racing breaking the Race and World monohull record for the route.

    The last boats have finished the race and a nice article to round out the event was authored by Trish Jenkins. The race was definitely hard graft for the smaller privately owned craft but credit to them for toughing it out.
