It was F4 gusting F5 and the wind direction gave us a course comprising a 6 mile beat, a 4 mile close fetch,
then on the way back a 4 mile reach and a 6 mile dead run.


As someone who sails neither Blaze nor FF, can I just comment that I would expect the Blaze to do better than the FF in
the conditions posted above. The Freds I have raced against (which include some real hotshots) have a distinct advantage
on handicap in sub-planing conditions. When you get into F4-5 territory, all that weight makes them distinctly slower
than would otherwise be the case. So the Fred is at a disadvantage in those winds to the average.

The Blaze looks to me like a decent planing hull, and such boats tend to perform above their handicap in the windy stuff
and below in light airs, where they tend to stick in the water. Add in the close fetch where presumably the Fred
couldn't fly the kite, and you have the makings of a decent advantage for the Blaze, or indeed any other non-kite
planing hull boat.

We notice very similar trends between Solos and Fireballs here, these two also having their advantages at opposite ends
of the wind strength spectrum. It just highlights the deficiencies of the handicap system, but I don't think you can do
much about it.

You hit the nail on the head there Mikey. Due to the racks you get a lot of righting moment on the Blaze so you really can drive it hard on a tight fetch where other boats are tending to have to depower and spill.

I used to take great delight leaving the Phantoms for dead on a close fetch/tight reach when it was blowing.... happy days!

Wonder where you came in your FF15 Nationals ?


Hey, I certainly don't claim to be any sort of hot-shot, and my Fifteen is a 35 year old "shed" that I bought for £300 and have thoroughly enjoyed renovating.

On the event in question we were having a "good day" and ended up 6th overall, so I certainly wouldn't use my own performance as any particular yardstick (pun intended ). But what prompted my thoughts was that one of the quicker Fifteens was extremely well sailed and got well away from the rest of the fleet yet still got absolutely trounced by the Blaze's.

Meanwhile, I would endorse your comments about the leading Blaze. But what is interesting is that he too absolutely blitzed the other similar boat, by an even bigger margin than the leading Fifteen had over us, and yet even the much slower Blaze beat every other boat on the water, and by a country mile on handicap.

As you might appreciate, that started a fair amount of conversation about handicaps amongst those present on the day.

To conclude I would re-iterate that my original post was not in any way intended to be confrontational, just trying to provoke an analytical debate.

Which by and large it seems to have done, and I agree with the comments posted by others regarding wind strengths and points of sailing. Perhaps the answer to my other hypothetical question is that for next year we want the breeze to be 40 degrees more northerly, then we can beat all the way up and fly our kites all the way back!

As an aside, both my crew and I commented on what a lovely looking boat your RS300 was. To be honest all the handicap debate probably started from a comparison between the Blaze and the RS300 which to us looked broadly similar boats, and we would naively have expected to run at similar yardsticks of c.1000, albeit based on the limited "snap shot" we had of them sailing in those conditions on that day.

The 300 should be quicker then the blaze, but by the sounds of the course and wind that was 300 teritory.  Blaze must of been very well sailed!

.... and I'm sticking to the original suggestion that Halo is about 20 below the Blaze.  It is very like the Blaze only faster and also suits a heavier helm. The numbers as simple avarages that reflect returns from all sorts of locations and in a wide variety of conditons.  Blaze/Halo are both optimised around their planing characteristic and high leverage - we fully expect both to 'beat' the handicap avarage in higher winds than some other classes as a result.

Sorry,I was also not meaning to be confrontational. Point I was trying to make was that really good sailor can make a nonsense of the given PY figures at the best of times. Factor in a wind speed/direction that favours that particular class, and you're example at the Windermere shows the results.

As for comparison with MY 300, again in this instance, it can be ignored cos I simply can't sail the thing properly !

In my experience you cannot have a debate about PY's without confrontation! People get very defensive about their PY's and rightly so because the slightest suggestion that you have a beneficial PY is tantamount to saying that you are not as good as youre results suggest.  There is a million different aspects to consider when comparing PY's.  If you can master a difficult boat like the 300/700/skiff etc you will have an advantage because the PY assumes that half the fleet will struggle with boathandling.  Similarly and one that gets to me, is when a very good sailor sails a training/family boat.  The PY for these boats being set on the average ability level of the fleet! 

The worst example that I have come accross was with the Laser EPS. I raced one of these for a season off 1013.  It was the nicest boat i had ever sailed but the PY all but killed off the fleet. It is a testament to the design that they are still going today! They were no quicker than the blaze.  The RYA's response is that without sufficient number of returns, there is nothing they can do. Catch 22.

Sailing club Bar rumors are that the Phantom is going to get a serious drop in PY this year, has anyone else heard this or should i ignore it?  If they did drop it do you think it would have much effect on the fleet size?  I often wonder if part of the success of the Phantom in recent years was the fact it is a Bandit round small gravel pit type clubs of which there are loads?

If the gravel pits have been filing good returns, then the PY should naturally drop as part of the semi-automated process if it really has been such a bandit, surely?
