irc displacment is based on the number of crew and equipment required on board.

i think most the boats have this 'larger keel'. there is definately a difference with them.

I've been digging through my old certificates. Initially standard hull data was
used (1300kg) but it was weighed in 2002 and the empty weight was
1240kg. The boat had 68kg added to the keel and now weighs 1308.

This is my first owned boat so I'm not great with certificates yet. What does
IRC Disp mean? Mine is 1780

i agree with the larger kite and smaller headsail for irc racing. this is our plan if we get the money to do it!

if this change was not made, ie keep the same sails then i believe added weight is the answer. this is because the amount of speed lost downwind would be very small considering the boat only planes downwind in upwards of force 3-4. windward performance would be improved, more so in waves with the added hull weight.

Garth, unfortunatly Falmouth is the same week as the Fastnet. If current plans work out we'll wave as we go past (it won't be Zulu, though!  )

On the IRc front, my current feeling is that the 762 would benefit from a masthead symmetrical kite (about 60 sqm) and a smaller headsail, probably a light 100% No 1. The rating will go up a bit, and as the recieved wisdom is that in IRC overlapping headsails are 'expensive' and kite area is 'cheap' it should be both more fun and worth it. I'd be very skeptical about adding more weight to the boat anywhere.

Anybody got any thoughts on this?

Kev.

Hi Garth ,

some of the crew have just scraped enough hol to do Cowes , my wife would not be impressed !   Its hol time at work and I need to be back to cover for my staff ....  would love to go to Falmouth ... however ... we are pretty well booked up regatta wise for 2007 , 2008 may be different though .

I've also been warned I will be a wreck after a week at Cowes , my young crew really like to party etc .. sleep will not be an option most of the time . 

Thanks for the offer though , we will meet on the water at some time ,

Doug .

Pumper Nickel is a Cowes regular in the Sportsboat Fleet.  However, why don't you do some real damage to the Credit Card and follow Cowes with Falmouth Week (12-17 Aug 07) - the extra few miles would be worth it and there are plenty of good campsites nearby.

If Brys & Zulu, both showing some interest were able to attend, that could make 6 of us and provide a real opportunity for a Projection Class.

it seems your boat is considered quite heavy at 1480, most ours are around 1350 when weighed. that might be just the different rating (i presume she hasnt been weighed). Also they have your draught at 1.707m, i wonder whether that is an estimate from the design drawings or measured. It seems a bit large. I would be interested what your IRC/IRM rating is if you get a certificate for Cowes Week.

I think a 2.3hp is fine in river, but not good for any waves!

Our mooring fees are quite cheap as well, makes you wonder why people pay a couple of thousand a year for marinas.

Mmmmmmmmmm ... sounds like my 2.3 Honda might need to be upgraded !

The crew have agreed to do Cowes week , which is a long way from here ( Northumberland ) , just booked a caravan ... wow! they certainly know how to damage your credit card . There will be a good number of SB's going from up here , would be nice if another 762 was there , I've heard there is normally at least one attends.       

      I have a H'cap of 95.98 from our local NERR system , measurements were from another boat in the system , my pole is a little longer and Hyde measure big kite at 45 sq m . Will be getting SBR when the 2007 info is avail.                  P 9309  ,  E 3630  , LL  8973 ,  LP 3914  ,  J 2609  ,  SP 3100  ,  BOW OH 152 , STR OH 552  ,  DISP 1480 ,  MAX DR 1707  ,  I don' understand all these numbers , I'm sure some of you lot will .

At our regattas we get moorings and craneage in with entry cost , the Club owns its own crane , travel hoist , pontoon and fore and aft  moorings . Some say we are a little spoilt , my seasons moorings last year were under £200 , we are now attracting SB's from the midlands to our events ... we are so far away from you lot in the south though !

Boat is Sail No 7622, called Zulu & we're based at Cardiff Bay Yacht Club. I doubt we'll be at Sail East, although Falmouth week either this year or next is a possibility.

Like you, we have some strong tides and gates to cope with. We do the Swansea/Padstow race every year, which for us is Cardiff to Swansea to Padstow to Lundy and home in a long weekend, and we did Dale weekend last summer (Milford Haven), nice trip down, wet, windy and fast back!

With the engines its easy to think a few kilos doesn't make much difference, but it does. Also, there's the matter of bulk as well as weight.

where do you sail 'some bloke' and whats the boat name? Are you thinking of competing in SailEast events this year?

As regards the 8hp, i think you are right with it being harder to move around, but its only a couple of kilos heavier. Supposively the fisherman love the 9.8hp as that too is the same weight as the 8hp at only 26kg. We have found last year that we had to sail and motor flat out to catch the tide gates for some of our deliveries which gets very tiresome. White Lightning, another projectiong from our club takes another boat with them which they sometimes use for towing. We have 4 events during the year, all over 60miles away, there and back over a weekend, plus the racing. Start to rack up some serious mileage!
