Topic: Projection 762 Help please? Posted: 16 Jan 07 at 9:32am |
In reply to an earlier post about engines, we have a 4hp Mercury 2 stroke. Flat out it gives us about 5.5 knots which isn't too impressive - but it only gets us in and out of the marina anyway. And talking of the weight of the keel, my boat actually has 68kg added as a small bulb. Having not sailed a bulbless projection I don't know how it compares but I plan to leave it as is for 2007 and maybe remove it next winter. Will hopefully catch up with some East Coast projections at PoFR and Dabchicks next year (anybody fancy Burnham Week too?) and see how she goes boat on boat. Had our first practice in the boat at the weekend which was great fun. Have posted a video http://www.youtube.com/watch?v=xVG430LJLRE |

We are considering doing the whole of burham week as we already have accommodation available. i'll have a word with the crew. Our engine is a 4hp suzuki and its fine on flat water but any rough weather stops the boat dead!!! it weighs about 22kg and we are thinking of getting a 8hp tohatsu as they only weigh 26kg (long shaft). we really need it for the delivery trips when the wind is in your face, the tide is falling and you need to get through the Swin Spitway! By adding 50kg of lead forward of the keel and maybe moving the outboards permanent position to the centre of the boat, the waterline length may change up to 10-15cm. This would have no affect on performance as you just move bodies aft. (You can see this by simply getting somone to stand towards the bow.) Only time you may notice this change would be in large waves and heavy winds. But you could account for this by putting your extra sails under the transom. Its just a thought to get around the IRC handicap problem. Simon |

I used to have a 3.5 Tohatsu vibro-massage machine, which occasionally moved the boat along a bit as well. As we have to lock in & out not having a reverse was a pain, so I have changed it for a Merc 4hp 2stroke "Sailpower" this is a longshaft engine with a charging coil and also a high-thrust prop optimised for 5knots or so. It is a bit heavy at about 23kg but is brilliant. Drives the boat against wind & tide and very seldom throws the prop out of the water, which the old tohatsu used to do all the time. I would advise one of these, I'd expect an 8hp engine to be very heavy and cumbersome manhandling on & off in any sort of seaway.

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! Simon Edited by simono |

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. Kev, GBR 7622 Zulu, CBYC

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 !

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. Simon |

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. GBR7620 - The Big Purple |

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 . |

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. |
