Gentlemen - this thorny subject needs to be mentioned before the season commences...
The Rules. No, not those ones that your wife/girlfriend changes every day but the ones pertaining to our boats. what are they?
Since my hole in the water was surrounded in fibre glass in the late 70s, lots has happened to the way boats are constructed and tweaked.
My reason is that Egret, my E-Boat, has class rules in addition to those that originally applied to 'pure' mini-ton yachts. Oh, and my carbon boom will be fitted over this winter, an item that, like my laminated headsails and the position of the on-board battery, would lack conformance to E-Boat class rules.
Looking at the example of the quarter ton class, these trifling details don't really seem to matter. I take it that we are following their (successful) example?
Do we have any thoughts or 'official thoughts' on this subject?

The main class regattas will be run under IRC as this is currently the fairest way to conduct racing. Yes, it involves rating the boats - but if people are going to take the trouble to organise the crews and boats for participation in a proper event, then it seems only right to use the fairest rating system available.
I understand this has worked very well indeed for the Quarter Tonners and takes care of 'modifications'. For many, (Sonatas etc) rating will be an easy affair anyway.
I am sure as racing of Mini Tonners happens in other regions and as an addition to pre-existing sailing events, the boats will be raced under the organisers' own systems as well.

yes. as matt has said. irc measures & rates each individual boat so in theory it wont matter what you have on your boat. ie 2 nearly identical boats carrying different ballast will have different ratings to one another. and so on. the good bit is that irc is not an expensive rule to measure under as you do pretty much all the measuring and then send it off to rorc. hope this helps.

Care will need to be taken here as the rating office will have standard data for the E-Boat despite it not being an IRC one design. Moving the batteries will cause a change of trim and so alter the overhangs fore and aft which may also alter the waterline length. These will need to be measured and a note put on the application form to explain why your boat may differ from others. All these effects may give a higher or lower TCC depending on where the weight is moved to. IRC weight is to the nearest 10 kg so changing to a carbon boom is unlikely to decrease the measured (standard) weight however the rating office like to know about ANY changes made that may improve boatspeed. A carbon boom may cost an increase in rig factor and so an increase in TCC. The rating office did ask about boom material for a couple of years (about 2004) or so but they don't seem interested any more. If of course you have never had a rating for this boat then you could fill out the form and as it doesn't ask boom material, ignore it. Its all part of playing the IRC game. As a sailmaker (of past) and EAORA safety inspector, the vast majority of boats I sail on or inspect don't comply 100% with their certificates or the -admit all- spirit of IRC. There is a lot of 'being conservative with the truth' going on! I hope this helps.

Good question Ant.... I think people often perceive rating is expensive, however, as Will mentions - since you are responsible for the measuring yourself, the cost is mainly your time and the standard application fee - which can be made online (an Excel Spreadsheet) or by paper. Fees are currently: New application (Excel) £8.90 pm (Actual LOA) New application (Paper) £11.20 pm Thereafter, to re-validate the certificate each year is £7.75 pm. So around £60 Quid for the first year and £50 to keep it up to date. The form is very straightforward if you have a standard production boat such as an E-boat, Limbo etc . Otherwise, there are a few simple hull measurements to make, to explain the principle dimensions: LOA, Beam, plus overhangs etc. The main thing that takes the time will be the rig/sails - as these need to measured (which is easy - or you can ask your sailmaker to do it for you - though there may be a small charge). All the links and the Excel form are available here: www.rorcrating.com/ocean-safety-irc.htmlI recommend you download it and have a look. Once you start to complete it the mist clears away quite quickly! Incidentally, I spent a while putting some FAQ's on the MT site, as there are no major worries like weighing your boat or having to get things professionally measured for the regular IRC certificate.

i have got to the weighing stage of my form and am now confused, do we need an endorsed form to do the minitonne events? can i just use the standard displacement info (i.e. 975kgs for the eboat)? or do i have to go to an official weighing place?

ahhh i think i almost understand, if i leave the hull section blank will they use the standard hull data?

The easiest thing to do is use class standard data for length, beam, draft and weight (so long as its a 'standard' E-Boat). I expect the weight is more than 975 but if the rating office have weighed another E-Boat recently, they may/could/should use that weight unless they believe it to be different or in error. Endorsement is not necessary, Shallot is endorsed only for scoring club points in EAORA. Further to weight, Shallot weighs 1370 empty, and Blue Movie (Limbo 6.6) 1330, I'm sure both these designs were advertised as displacement of 900 - 1100 back in the day. If you want to weigh, the cheapest way to do it is at a weigh bridge. Get the boat in measurement trim on the trailer (see IRC rules text fo what can be aboard), weigh the lot and then weigh the empty trailer and make the subtraction. This is acceptable at the rating office (but not for endorsement).
