Hi, As most of you probably know (seen the pics etc) i sail a 600. Firstly as I'm only light I have to have wide wings and a 3kg weight. I currently don't have a weight and aren't really willing to throw 30quid at RS for one? So... would it be class legal if i made my own weight? My Dad has loads of lead and the means of melting and moulding it, what do you reckon? Secondly, My center board slot is about 1-2" longer in length than it needs be. I've tried using progrip and furry tape to pack up the slot but it just jams on the side therefore it didn't work?! Ok, so my board can move back and forth about 30degrees, would this effect the performance? At the moment i can only think of two ways of solving the problem; either build up the top of the centreboard, or build up the inside of the slot? Any other ideas? Thanks in advance! Mark. ------------- RS300 - 346 :D |

Your centreboard slot should be fine as long as the board doesn't move while sailing, from memory I think the board is a bit smaller than the case on all the boats. If it does move have you tried filling up the back of the case with epoxy? Or perhaps having a couple of rubber stops on the top of the board, one near the front one near the back to stop the board rocking back and forth? Weight-wise, the rules say you can substitute fittings from other suppliers as long as they perform the same function, as the weight just has to be heavy it certainly fills the same function, and if you count your dad as a supplier then in theory you're fine! Although if you are below 70kg you don't have to carry the weight. ------------- RS600 1001 |

Mark, Best place to ask is on the Rs600 yahoo group, although a few of us lurk here. Although the weight might not be strictly class legal i doubt anyone would object, i sailed at the Looe nationals with 3 liters of water tied to the bulkhead after i discovered my scales had lied!! The wear on the center board does sound excessive- mine moves forward and aft about an inch max at the tip. The back of the case is also a common spot for leaks so sounds like it needs sorting! Cheers, Mark 717 ------------- RS600 717, RS400 870 Netley SC Kerr 11.3 (Pier View YC) |

ive just sorted out the back of my daggerboard case, get a piece of wood and a felt tip pen, wedge the pen into the back of the case with the piece of wood (prop the wood into the front of the case and get hammer), then check there are no holes (send someone under the boat with a torch, if you can see light between the pen and the case work something else out) and finnally just drip un thickened epoxy down the gap. leave it a bit low and the last bit can be done with gelcoat. it worked fine and the boat was a lot drier at the bloody mary than it has been. the only problem is the bit of green plastic left in the case, im calling it "strengthening". as for the lead, i can't see why it wouldn't be class legal, as jamie says, lead is only there to be heavy. however there is something in the rules about it being distributed symetrically about the centre line. ------------- 600 732, will call it Sticks and Stones when i get round to it.

No you definitely don't need to use them, I used to race at about that weight too. ------------- |

But then don't i have an huge advantage over others who are heavier than me tho as my overall boat weight will be less... or should i just keep quiet about that ------------- RS300 - 346 :D |

the keeping quiet about it works well, and TBH an old boat like yours is probably carrying around extra weight anyway, mine almost certainly is. ------------- 600 732, will call it Sticks and Stones when i get round to it. Also International 14, 1318 |

I found it was only really on tight reaches in medium to high breezes that I was at any significant disadvantage as the heavier people could keep the main powered up and drive over whilst I was left overpowered with the sail flogging. Upwind is a matter of technique and in some of my better moments I found myself pacing some of the good guys when it was windy. Downwind provided you stay upright in the gybe then you're laughing.... I mostly wasn't. ------------- |

Thanks Guys, I'll have another look at my board when sailing at the weekend. If i tie the elastic tight enough i don't think it does moves. Thanks for the idea Mike, my boat is dry with no leaks and 'major' repairs so i doubt its much heavier... with my new sail i was wooping the other 6's, B14 and 29er last week i some mini races Just thought of another quick question... I've just had fitted a new mast track but i've still got the old sail feeder on. When hoisting my sail i could only hoist about an inch at a time as it poped out between the sail feeder and track. We took the feeder off, filled it with epoxy and drilled a new hole and grove but havn't yet tried it. I really should buy a new one is there a specific one i need? Thanks again Mark. ------------- RS300 - 346 :D |

Apparently the older boats in the early 600 numbers are built to a higher standard, and RS lowered this as they had to build more to demand. I think there were some serious problems with either the 7 or 800 numbers. There's a possibility that the early 600's were Ovington built?? Can't really remember, maybe someone with a better memory than me would care to clarify??? ------------- |

Early 600s were indeed built by Ovington. Production switched to RMW somewhere in the 800 numbers I believe, certainly my old boat GBR783 was an Ovington boat. You can tell the difference by looking at the gel coat, Ovington grey is lighter than the RMW grey and doesnt seem to have the slight green tinge to it.
All the boats were built solidly and the only issues with quality crept in with a batch of RMW boats in the 900s (around 924 I think), The problems cropped up due to new staff at RMW not understanding the build process fully and I believe that a few bits (bulkheads) were missed out in the build. Matt Humphreys boat suffered this fate and he found that it flexed visibly around the daggerboard box/ kickbar, and ended up with the rudder post cracking away. LDC took these boats back seperated the deck from the hull and fitted all the bits they'd forgotten first time around and sold the boats on, I believe as approved seconds. So dont worry about 600's they're bullet proof. |

I did a month's work experience at Ovi's in 1997(?) and they were building the 600s then. Amazing build quality and attention to detail. ------------- http://www.sailns14.org - http://www.sailns14.org - The ultimate family raceboat now available in the UK |

Mines got a serious grove in the back of the case which means the board can move massivly. The boat also leaks and is getting progressivly worse. It was sinking at the back at the BM through tacks which was very annoying. I'm going to have to stand it on it's end and fill the grove with epoxy and some other wonderful substances. ------------- Greatfully Sponsored By www.allgoodfun.com Int 14 GBR 1503!! |

you dont need to stand it on its end, turning it upside down worked fine for me. (is that george not alex?) ------------- 600 732, will call it Sticks and Stones when i get round to it. Also International 14, 1318 |

If you stand it on it's end the back of the case is then horizontal rather than vertical so you're not trying to work against gravity ------------- RS600 1001 |

but you need good weather or somewhere wih a 14 foot high ceiling. also can you get high enough up to be able to see what you're doing properly if you stand the boat on its end? ------------- 600 732, will call it Sticks and Stones when i get round to it. Also International 14, 1318 |
