Reflections : SHRS and HMS….!!

Running up to the IOM Worlds, the subject of SHRS race formats did come up in conversation a few times. Since the IOM Worlds, unexpectedly it has been mentioned a lot more. There have been three broad topic areas:-

  • enabling larger fleets brings bigger entrant fee income, and large championships are VERY expensive to run
  • SHRS is less prone to Protest linked regatta delays or pauses in racing. I must say, the Worlds were much more “protesty” than I have experienced before. A good concern to have.
  • intriguingly, this months hot topic has been blending SHRS and HMS together in one event

Reflections based on the Datchet IOM Worlds experience?

First off, I wish we at Datchet had real live experience of organising and running an SHRS event. It’s great that we have three race formats (single heat, multi heat HMS and SHRS) available and the management tools that go with them. Brilliant, actually. The sailing sport faces a wide set of outcomes that it might want to address. We need choice! It’s unlikely, especially radio sailing’s high volume, sprint race kind of format, that one tool could do everything. So choice is good!

Quite often it has been said to me that SHRS will be great when the entrants fly in and are basically captive for the week. Everybody stays to the end, right? If your Championship event entails competitors driving through national traffic,…. if competitors don’t feel engaged on the final day ….. do they withdraw and leave early? You bet. Is that just Brits who do that? I don’t know! (From a personal viewpoint, for 60 years people not staying to applaud their own winners at the prize-giving has disappointed me in the extreme. But it happens…)

Maybe the way to look at it would be SHRS for “fly in” championships and HMS for “drive in” championships. If you have a view, write into the website and let us know.

Let me deal with the three common questions arising above:-

1/ Fee Income goes up with SHRS

Let’s suppose you have enough demand for a 100 boat regatta, way above 84 boats. Call it 20% more.

There’s no point thinking this is the Holy Grail for Regatta cost coverage. At the IOM Worlds, we saw half to three quarters of the basic entrant fee income being absorbed by costs as a direct function of the number if entrants. If you’re chasing a financial surplus, or simply trying to avoid financial ruin, then you might think more than twice about SHRS bringing salvation.

2/ HMS brings race pauses and regatta delays from Protest Management

Well, this needs a good look at really. This was my first personal experience of a fully umpired event. we had many more protests relative to a UK focussed event, and the general level of rule observance was possibly a weeny bit controversial.

Inevitably you will wonder how many umpires have to hear a single protest to reach a decision. As you may know, in HMS racing we have historically avoided Standard Redress awards as the scoring software in HMS Excel has no support for it. It’s awful without as it’s manual calculations all the way. What if Standard Redress scoring was fully automated?? If Umpires thought they had a free hand to distribute Standard Redress awards, could it make non-SYRPH protest hearings shorter? Afleet’s standard redress support is kinda of 95% automated already, but what if all our scoring platforms had a 100% fully automated Standard Redress capability? Could the Umpires use that confidence to use these awards to try and shorten hearings?

3/ Blended SHRS and HMS Events

The first time I eavesdropped one of these conversations, I wasn’t sure what was being suggested. It sounds like one or more of the European countries have an idea to run the first three days of a large championship on SHRS, then at the great SHRS split of the fleets jump into HMS heat based racing to keep engagement high for the last couple of days. What do you think of that?? (let us know)

It’s interesting, but a couple of quick thoughts from us:-

  • if you have taken the opportunity presented by SHRS to boost your number of entries above 84 boats, how to you transition perhaps a 95 boat fleet into HMS for the last two days??
  • One answer may be to enhance HMS Excel, but you may find it useful to know that AFleet has been tested at the 96 boat level. Interesting.
  • at the end of the SHRS phase, do you simply load scoring on an HMS system using the current “position” like a ranking table?? Maybe that would be fine.
  • We cannot physically expect PRO and competitors to manage more than 22 boats concurrently on the line. Good point, but what’s involved in lifting the maximum number of heats from five to six? It might be easy-ish to do in Excel, and Afleet could do it easily if asked.
  • The HMS Rule book schedules A&B for determining heat-based fleet structures/sizes don’t go high enough. Well, not difficult probably to write some more schedules, and in Afleet at least the heat sizings are done by an algorithm, not by table lookup. The algorithm can could handle larger fleets than 84 or more heats per race than 5…..
  • If a venue could support heats above 22 for some reason (eg control area location), what about the “promotion setting” choices moving from 4 or 6, to a 4-6-7 type choice? Could be written for Excel and for Afleet it’s not a big deal. There will be some choice of race pattern where a competitor gets more races in on HMS than SHRS?? I don’t know, but probably someone can write in and tell us !!

On any of these types of answers, first up you need to get the skilled volunteers you need to score the event. A large concern actually. By the way, there is more than one camp looking at providing a scoring platform that deals with HMS heat based racing AND SHRS based racing inside the same scoring system. That might make finding skilled volunteers a little easier……

IOM Worlds : What Did the Final Checklist Look Like …??

If you’re planning a large radio sailing event at your Club, we thought you might find it useful to see the final checklist we used at Datchet for the IOM Worlds.

Worlds …. Flagpoles…!!

(Above : Half the IOM Worlds flag set)

You cannot really run a continental, global or world championship without country flags can you?

There’s the traditional Opening Ceremony for a start and I wouldn’t underestimate the importance of making the race marshalling areas look a bit more jolly!!

We had 28 countries in attendance. No matter how you look at it, just about any budget number that you have to multiply by 28 is going to end up being a four digit sum. If you take a minute to work it out, the income fees for 84 entrants comes to around £40,000GBP. So if you’re not resourceful, you could be looking at 5% of Championship income just to pay for the >*&+<& flags!

So what to do? You’re only like to use them the one occasion at your club….

For a start, where to get your collection of flags from? We used “The Flag Shop”in UK. We ordered pretty large flags, maybe 5’x3′, (see photo) for each country. They must have stocks of flags already made, but if you order all 28 at once it turned out to be quite low cost. I recall maybe £300-£400 for the set of 28. If the Championship WDN/Wait-list springs an extra country at the last moment the cost for one flag was a LOT higher.

TIP : grab an indelible pen and label them all upon arrival with country name and “TOP” …well in advance of your championship ceremony. It’s easy to cause offence by flying them upside down. The Union Jack is not the only flag with this characteristic.) NO human really stands a chance of remembering 28 flags by country name.

Your venue is unlikely to have a nice stock of flagpoles to accommodate 30 or so countries, so you might have a procurement problem. You need around 4m high poles, with block and lanyards … all times 30. Financially that’s a big part of your budget right there. If you can get a rigged 4m flagpole for £30 each I’d be amazed. Let’s say £1000 of poles. So what to do?

Our venue host is a 50 year old dinghy and keelboat club. You’d be amazed what broken masts and booms get dumped by club members as the decades sweep by. In fact, Datchet had the entire history of mast design and building right there hidden in the pile…. Selden/Proctor sections, carbon masts, tracks riveted on/inbuilt, laser two section masts … and an old wooden enterprise mast!!

I’m not going to kid you that it was a small amount of work, but saving £1000 of budget is a huge deal.

A couple of lovely people teased us that we got the flagpole lengths different each time (see photo above)…. but were generally delighted to see the recycled materials that the flagpoles were actually made from.

The work involved:

  • we had one day with around six or seven DRS volunteers sorting the old masts, stripping spreaders, hounds and various fittings from them. Our sailing sec, Hugh, is a demon with the angle grinder and cut around half of them to 4m (ish) lengths on day one. If they were topmasts, they usually had a masthead fixing we could re-utilise. Sounds a lot of man-hours, but honestly it was a ton of work.
  • On day two, Hugh-the-angle-grinder-king, cut the remainder to a length and ensured we had a top fixing of some sort …. and that from our sponsored flagpole halyard supplier they were all rigged with a hoist lines.
  • On day three it took three volunteers to fix 28 or 29 poles to the landlord’s railing uprights. It took two scaffold brackets per pole – we got around 60 from somewhere but I feel the cost was around £150 for a box of 60..

Saved a fortune.

Post championship, I was about to start quietly dropping the flags (what to do with those? Sell them to the next Worlds?) and taking the poles down maybe two per day…., then the Dinghy Club Manager said it all looked great and could maybe a continuing club asset – they host lots of school and junior events for example. Flags a nice feature there…

Good!!
