Radio Sailing – a Sport with Pretty High Barriers to Entry…. !! A Surprising Role for “Match Racing”??

A rambling sort of idea coming….

Like many clubs, the main sailing club at Datchet has seen its dinghy and keelboat fleets in strategic decline. However they have done a simply brilliant job of growing their K1 keelboat fleet and now have 22 boats, all pretty new. Suddenly it’s the largest K1 Club in the country. Now the two biggest social groups in the Clubhouse over coffee are Radio sailors and K1 sailors!!

I was browsing through my shore-side photos of last week’s Marblehead rankings. You only have to look at our crowd to realise that encouraging new blood into radio sailing is a major strategic challenge for the Sport in general. In ten years time, frankly we shall all be mostly laid-up or gone. Game over. Ten years isn’t long. We need to at least focus on replacing radio sailors who have to retire, then move on to attracting a new generation.

It often seems to me that some UK radio sailing clubs have this topic cracked. Datchet is blessed with the most friendly and supportive fellow members that you could find anywhere. At least half of why I sail there is the warmth of the people. But is there more to do, somehow?

In my dark moments it always seems to me that whenever we get visitors for a championship the average age of attendance goes down!! So in some UK regions, radio sailing members have been working on this…. In Australia, I follow the Youtube channel for the Wynnum Manly Club. Have you seen that ?? – they put a huge amount of effort into making entering the sport more easy, less fearsome, deal with beginner issues and so on. Super!

With my Flying Fifteen partner Howard, we have both been trying to make the transition to radio sailing. We find there’s quite a lot of new things to learn (!!). Plenty of fear of embarrassment getting in the way!! The barriers to entry are pretty high.

Aside from the terrific DF95/65 product getting hold of a boat is pretty challenging in itself. Then there is the issue of finding more ways to simply get started – learn to sail a course without hitting marks… or other boats.., get boat handling basics right etc. The standard way is “come and join in”, but lets face it, this can be daunting…even off-putting for some. I notice that SailboatRC has a one week kind of course in Croatia, which starts with a navigation race – just sailing around the buoys.

At Datchet there is so much support, and especially knowledge. available to help. Even the supply of new boats is being tackled. Gradually we are moving towards a picture, of “if you want a new boat to sail here, we can get you one”. Amazing.

It reminds me that last Saturday, a great keelboat racing friend called for a long chat. Despite his big boat collection, he also has two IOMs, plus is building a woody. He tells me that he likes taking the two IOMs out for friends and family social match racing… mainly I think to get his young kids into radio sailing. (Good!) In parallel, I’ve decided to get a second Marblehead so that when friends sounds like they would like to try radio sailing, I have a simple way to have a two boat day with them and have some fun.

I’ve been wondering about race formats for two or three learner competitors to have fun and embarrassment-free fun, safely on their own. Two boat racing and simple knock-out type racing springs to mind.

My keelboat buddy says that when he takes family and friends out for 2 boat IOM fun, there is always one big challenge. One of the two boats on the water is always dominant. It just makes it boring for the other skipper. Sometimes it is that one boat is naturally faster, but more likely one skipper is notably more experienced than the other. Quite often they simply race to a windward mark and back, or a simple windward leeward one lap race. The big innovation that they fell into was that at every turning mark, whoever is the lead has to do a 360 turn. He said that simple idea has just been magic to keep the second (and first) sailor motivated.

I have two or three friends who I can tell would like to “have a go”. When we add the N+1’th boat to the family fleet, I shall give this idea a determined try. Perhaps the friends can then also give me a feel for what a Club Course titled “Learn to Radio Sail” might actually look like. The Club has a big “Learn to Dinghy Sail” program each year and loads of kids (and some adults) have a try. Maybe the parents might like to try radio sailing when the kids are “out there”.

One step at a time though….

Beginner’s Guide : Losing Contact with the Boat and Diagnosing That It Turns Out To Be Moisture in the Electrics…..!!

I’d heard a lot about this subject as a beginner. It must happen a lot !

As you may have seen on the website yesterday, during the Marblehead Rankings Nigel B lost radio contact with his F6.

It turned out to be “damp in the electrics”. We had only one discard in the day, so it was really important for Nigel to diagnose and fix it quickly. This is what he did (very rapidly!):-

1/ Boat on to the stand, pot lid off, and quickly verify power in the boat and especially at the receiver because the receiver’s LED was glowing green. Waggle the two joy-sticks to determine what was working and what was not working.

2/ Sure enough, for Nigel the rudder was not responding, but the mainsheet was OK. Conclusion = not a complete closedown and there is power in the boat. Good news.

3/ LED was green so that tells you it’s in the rudder setup somewhere. Where to look next?

4/ Statistical guess : rudder servos don’t fail all that often, so the connection where the rudder circuit joins the Receiver is number one suspect. Pull out the connector to channel one and have a close visual inspection which revealed the wicked glint of moisture.

5/ I’d heard about a product called “Corrosion X” before, but not seen it in action. It looks like WD40, may be a bit thicker perhaps. It is supposed to do all the WD40 type things plus be the best water dispersant and repellant that money can buy,… safe on electronics especially. Anyway, out comes Nigel’s Corrosion X aerosol from the van, …squirt squirt…. deep into the connectors of the receiver… right “in” there….I must say Nigel was not afraid to be generous. Then a good blow to help the excess away. I don’t think it needed a moment to dry or anything like that.

6/ Plug the rudder circuit back into the receiver, checking the plug is the correct way around (!!), instant fix !! Waggle joysticks and “job done”!!

7/ Pot lid on – go racing !!!

Lessons :-

a) I think GH uses Corrosion X as a regular setup tool (not just a “fix”) on the electrics. Interesting.

b) someone in the car park probably has a can of Corrosion X, but I resolved to get a 250ml can from Amazon and keep it in the car….. WRONG!!

This photo above is the smallest, cheapest Corrosion X unit on Amazon. Obviously to all of us, 250ml will last a radio sailor several lifetimes. However… I made a mistake because that trigger on the can is NOT an atomiser. Squeeze the trigger and there’s only one adjustment size…. A thick rod of lubricant shoots out – honestly one squirt would make an entire Chieftain Tank very slippery !!

You actually want the smallest aerosol can that you can find online. (see Nigel’s in the top photo). Eventually I had to go to the manufacturers own (UK) website and order it there. 475ml was the smallest aerosol …so two friends can share one, each for a lifetime. Shipment from amazon is free of course, but CorrosionX use Fedex so your total price is bumped up a lot. 475ml was though near the same price as 250ml with the trigger on top, so keep a sense of humour and sense of proportion about the whole thing!!

If you know anyone with a Chieftain Tank, let them know I have something for them….

Inside the Receiver Pot of a Champion ….!!

You may have read that the Marblehead Rankings at Datchet last weekend had a few wilder moments weather-wise. My goodness, Nigel B had his share of issue management on the Sunday !!

For Nigel, it turned out to be damp in the receiver pot. I shall shortly put a “Beginner’s Guide” article on the website about how Nigel went about diagnosing this particular type of “lost radio contact with the boat” occasion. It was really quick and only one race was lost – very impressive!

Before I do that, I thought you might like to see Nigel’s highly ordered approach to the interior of the radio pot itself.

If you take a look at the photo above, note:-

  • Both battery and receiver attached to the upper side of the pot with velcro to keep them away from washing moisture in the bilge. The receiver sockets are uppermost as far away from trouble as you’d expect to get. Can you see that both battery and receiver are about as close to the lid as possible?
  • Vapex LIFE battery I believe, which last time I looked means the XT30 connector is a special order item!
  • Relaxed approach to antenna management – ha !! Looks neat though.

Nigel has two great additional tips:-

1/ Fit a breather pipe so that plunging a “warm” hull into cold water doesn’t suck in water through some weeny hole as it cools. GH says it can also help the hull to stop pumping the air pressure through waves. Try flexing the sides of a modern Marblehead and you’ll see what he means. The general idea of both members is that this is a great way of keeping the hull dry inside. By the way, I noted at the weekend that around half the fleet had breather pipes fitted. Many had a special little Sails-etc breather post (very smart looking sort of shark fin thing !), but on Henning Faas (spectacular) new Niou Niou it was a simple pipe buried in the deck patch. This approach is also favoured by PH and k7yachts here at Datchet.

2/ The standard pot comes with a thin plastic shim which sadly does not prevent water ingress. NB says that Tony Edwards had recommended getting a sheet of 2mm foam off amazon and putting that inside the pot lid as a seal. Highly recommended as a near to perfect closure. You can see it in the photo above.

3/ I must say too that it can be a good idea to keep a little vaseline in the tool box to smear around the pot lid thread for water proofing.
