I am a little out of touch with the current IRC rule - do you get a rating cut for having a wood burning stove?Edit: but with a wood burning stove - obviously!

I do hope John Corby's aga will feature a bolt-on warm panel for keeping salopettes neatly flattened?
As noted above, in the past when racing machines have been favoured boats have lost value so quickly that new building slowed dramatically anyway. I've often thought a good workaround would be to allow people to remove things like tables as long as they put a little bit more weight on board, bolted down in an area that would prevent it being used to improve weight centralisation or as ballast.
It would be good to allow lighter boats to be competitive, and to require the heavier ones to have simple things like forward bulkheads if they are going to be rated as cruiser/racers.
Full cast iron wood burner with chimney - up to 0.010
Obviously IRC is a black box rule so we can’t tell anything for sure, but the rumours are:
Eberspacher - 0.001 to 0.003 drop
Butane heater - up to 0.005
Bulkhead mounted charcoal - up to .007
Full cast iron wood burner with chimney - up to 0.010
Furniture - yes IRC adds a small amount for each item of fixed standard furniture that is removed for racing. The reason for this is simple – owners of cruisers or cruiser/racers should not feel that they have to strip the table and doors off their boat to keep up with everyone else. The standard level of interior is taken into account in the rating, so if people want to strip stuff out for ergonomic or weight reasons then why should that not be taken into account?
To what extent does RORC take into account the type of boat that is actually available to buy when deciding whether any tweaks to the rating are in order to encourage a particular type of boat in a rating band?As you will all be aware, IRC caters for designs from 1720 sportboats to classic superyachts and everything in between as long as it doesn’t have more than 2 masts. No rating rule is ever going to be perfect, and the question is ‘what type of boat do you want to encourage?’…. Whatever that is, it will of course not suit everyone.
Hi Flaming,
Yes – IRC rule 22.2.2 explains that Hull Factor may be increased for removal of furniture or other fitted equipment to compensate for potential increase in performance. It is interesting that you see this as a disadvantage for cruising boats, whereas it is intended to protect cruising boat owners from pot-hunters who buy a ‘cruising’ boat and then strip it out to gain an advantage not only in weight but in ease of sail handling etc down below. Accommodation level is part of the HF calculation so even without owners changing standard fitout it affects more than just the boat weight. I have seen very competitive production boats with all the standard furniture aboard but a protective cover over the table and the door handles taped up to stop them catching on sails.
The IRC Technical Committee does of course look at trends in design types and at different sizes. The trick is to work out what is a true trend (as opposed to a minority flash in the pan), what that trend actually is (ie. what feature(s)), whether it is undesirable and if so how to deal with it.

You have to wonder about a rule that allows people like us to put carbon sails, inhaulers, specialist racing tuff-luffs, uprated cordage and a whole host of other stuff that has an actual effect on how fast it goes on the boat with no rating penalty, ................ I fail to see how that encourages participation. By saying you can have all the go fast goodies without penalty you are saying that to be competitive you have to have them. So the average cruiser baulks at the cost. So we're not encouraging cruisers to race. Yet we're making racers sail boats with all the cruising goodies on board?
.
But you can have a cruiser/racer with good sails, a good Tuff-luff, inhauls and all the rest, and don't results like 8th overall out of 300 in the last two Fastnets prove that such boats ARE successes?then you can never get a successful cruiser racer outside a one design fleet
Hi everyone,
We (the RORC Rating Office) do not usually get involved in forum discussions, but having read this thread there are a few issues I can helpfully comment on.
The IRC Rating Authority does not say IRC is aimed squarely at cruisers or cruiser/racers; maybe it has in the past but IRC Rule 2 says “IRC is a system of measurement which classifies a broad range of cruising and racing ballasted monohull keelboats for competition… The IRC Concept protects the existing fleet… IRC encourages design innovation consistent with stability, rounded performance, seaworthiness and safety”.
Obviously, the ‘existing fleet’ develops along with design progress otherwise nothing would move forward!
And from the IRC introduction (https://www.ircrating.org/introduction/an-introduction-to-irc ):
“IRC is aimed at a very wide range of keelboats of all sizes and shapes including modern production cruisers and cruiser/racers through dedicated one-off race boats, older cruisers and racers to classic yachts and superyachts. IRC is continually developed to encompass new developments in both cruisers and racers while at the same time protecting the interests of the bulk of the fleet.”
Sailcloth – I have been working the Rating Office long enough to remember when CHS (IRC’s previous name) rated different sailcloths, and what a nightmare that was! Whatever rule you come up with, a clever sail designer or sailcloth manufacturer will find a way around it. Also, there were instances of people buying multiple sets of ‘low-tech’ sails and using a brand new set for each event. Unfortunately, that is the nature of rules and usually the losers are the boats they were intended to help.
Furniture - yes IRC adds a small amount for each item of fixed standard furniture that is removed for racing. The reason for this is simple – owners of cruisers or cruiser/racers should not feel that they have to strip the table and doors off their boat to keep up with everyone else. The standard level of interior is taken into account in the rating, so if people want to strip stuff out for ergonomic or weight reasons then why should that not be taken into account?
Extra, heavy fixed cruising items can be taken into account in the boat weight. Eg. davits, sprayhoods, windlasses, generators etc.
As you will all be aware, IRC caters for designs from 1720 sportboats to classic superyachts and everything in between as long as it doesn’t have more than 2 masts. No rating rule is ever going to be perfect, and the question is ‘what type of boat do you want to encourage?’…. Whatever that is, it will of course not suit everyone.
There are many aspects of design and sailing practice that IRC could take into account, but we are very aware of the dangers of ‘creeping complexity’ and actively try and keep the application and the Rule as simple and straightforward as possible for the majority of the fleet. We know that complexity is one of the things that can put off potential new racers, so it is something we have to try and balance with treating racing/cruising features fairly.
As far as the actual racing is concerned, things we remind event organisers about include: 1) vary the courses and do NOT just do windward-leewards, so that different types of designs have their day in the right conditions. 2) if fleet sizes allow, split out small sportboats from cruiser/racers as they perform so differently. This and more advice for race organisers is published on the IRC website https://www.ircrating.org/racing/race-management.

ps. yes, we have rated boats with a wood-burning stove installed!
But you can have a cruiser/racer with good sails, a good Tuff-luff, inhauls and all the rest, and don't results like 8th overall out of 300 in the last two Fastnets prove that such boats ARE successes?
To make it clear, the boats were a Ben 44.7 and a J/109, which are pretty similar to my own boat and more luxurious than our old one. We're perfectly happy cruising such boats for a week or two and would be happy for much longer cruises if we had time, especially with additions like dodgers, a watermaker and anchor winch which are either counted in the ratings or can easily be added for that annual cruise.
Uprated cordage costs a bit; inhauls very little. People like me may have to cop a penalty on our cruiser-style furlers but that's OK; we probably lose no more than one missed windshift. What concerns me is the $50,000 worth of extra sails the other guys can carry with no penalty, and which fill up the boat in a way that makes even a weekend cruise far less comfortable.
