Is there any reason to suspect that proportionally more coastal clubs (or fewer inland clubs) are now entering returns?

 I though the long standing complaint on this forum was that there were to many returns coming from inland clubs ? And that was affecting the pys in a unfair way.

The Blaze gets a few points back at Leigh & Lowton. Surely the state of the tide when races are sailed must average out the tide effect to some extent?

Slower boats (almostt) always lose out in tide. The only exception is if you race only with the tide…..ie a one way race, not an out and back, or If the tide turns precisely as the slow boat reaches the turning point.

Again I think this is expecting the system to iron out discrepancies thats its just unreasonable to, or if you do you make the data too specific.

It's not unreasonable to expect tides to pretty much even out over the course of a year (You won't always be beating into it and a slower boat might gain a benefit vs a spinnaker boat downwind if they can stay out of it and the spinnaker boat can't. That said I *do* agree that the tide mostly penalises slower boats) , or to expect the club (I think HISC did, how successful/popular it was I dont know.) put a tidal adjustment on their own results. This is easier with a large club fleet and decent data, a small club with 10 or less boats all of different classes racing is going to struggle. You also need a handicap officer with the skin of a rhinoceros.

Another observation of mine is the bigger the PY gap and the longer the legs of the course the harder it is to sail a slow boat to handicap relative to the faster one. On short legs/small lakes the reverse applies. I think once you go above about 125 PY points gap in nearly all cases it's very hard to sail to that handicap gap in an individual race and at most clubs it benefits one side more than the other most of the time. Thats why I've come the conclusion that if you cant have class racing you should at least do fast/slow if by any means possible as sailing a Topper vs a Solo is tolerable but vs an RS400 its almost meaningless.

I belong to an inland club.. We're 19miles inland by river.... But yes the tide has a huge effect, we can get an incoming tide of a couple of MPH, and at the moment due to the low rainfall the incoming tide is having more of an effect than normal..

As the sailor of the slowest boat in the fleet on handicap, it's noticeable while I can generally keep within a close range of the others going down tide, Soon as we turn up tide,, the rest disappear leaving me behind..

Ok let’s deal with this tides even out thing….

Into the tide (let’s say 1 knot) for 1 mile fast boat doing 5 knots through the water makes 4knots. Takes 15 minutes. Slow boat doing 4 knots makes 3 knots takes 2o minutes. Without tides they would take 12 and 15 minutes respectively. So fast boats exposure to negative tide is increased by 3 minutes, slow by 5 minutes.

When they turn to come home fast makes 6 knots and slow 5 knots. So 10 and 12 minutes respectively compared with 12 and 15 again. Critically the time exposed to facourable tide is shortened by the tide.

In terms of totals in and out fast takes 25 minutes (compared with non-tidal 24) but slow takes (compared with non-tidal 30).

Only when tide is favourable to slow on both legs does slow benefit (for the same reason as she loses….as the slower boat she has longer exposure to the tide so her gain from it is greater)

Up tide and then down tide it will always get you. The slower boats lose a bigger percentage of their potential speed uptide and they don't get it all back going the other way......at extremes the slow boats can stand still or go backwards 

Across tide the slower boats have to effectively sail further as they offset more to compensate.

Tidally adjusted figures are essential in my opinion.........but I can't see it happening ATM apart from at a few diligent, volunteer rich coastal clubs who can convince the membership to accept local adjustment. + Many folk aren't comfortable unless the format is written in stone by an official source. Perceived ambiguity and nuance isn't for everyone.......this isn't a dig either.

I don't believe the RYA help enough with this issue because they are also caught up in perpetuating the myth that PY racing actually means something at coastal clubs. In order to help more they would have to expose the fact that using one set of numbers for all clubs is a seriously flawed system. They do indicate that it could be bettered by locally adjusting but the degree to which it is wonky is not acknowledged fully. Emperors clobber and all that.......IMO it's time the RYA invested more time and money in sorting it out.

Also: There is an RYA survey being conducted at the moment. They want feedback about how folk feel about dinghy sailing, cruising and racing. Anyone else seen it?

At the extreme the slow boat may make no headway at all as against the tide whereas the faster boats will still be able to get round. No massaging of handicaps can fix that.

Ignoring tide and all that, the Great Lakes handicaps have a majority, and I say that loosely, slower boats getting slower too and there ain’t no tide inland for sure.   While tide is an impact on leg length, boat manoeuvres also have a bigger impact on speed the faster you go, so slower boats on shifty inland water and small course should be favoured!
