Well it’s been a long haul what with the major computer crash and loss of all sorts of important things but it’s a new PC, a new year and a new start ūüôā

To kick off 2010 we have the new OPUS rig kit available now as pre-production kits. Meaning that I do not have stock on the shelves yet but any orders I receive will be filled in received order as I complete the initial kits, finish the instruction sets etc. These will be the same as full production kits it’s just that you will not get them quite so quickly.

OPUS rig kit

The OPUS rig available initially has 140 sq.in. of area and is a good sized ‘working rig’ for average conditions from light winds up to a good blow.

The kit consists of a pre-assembled carbon fibre/aluminum boom unit which carries the rig pivot and mast mounting stub. The sail will be pre-cut with holes and requires a series of sailcloth loops to be attached along the leading edge to attach it to the mast. The carbon fibre mast tube requires a little epoxy work to attach the carbon fibre mast crane and binding on the lower end. After that it’s just down to tying a few knots and plugging the whole rig together. A mast tube will be included in the kit too. So you will be required to do some work, reasonably accurately, but nothing too difficult to achieve on the proverbial kitchen table ūüôā

There will be¬†full written instructions (working on that now) to our usual step-by-step standard plus a whole new section on the ScaleSailing Photo¬†CD which will cover all assembly plus a ‘how to tune your OPUS rig’ section which we hope you will find very useful.

The OPUS rig will suit many of the footy designs on the market with the addition of the mast pivot tube included in the rig kit. A little experimentation will be required initially to find the correct position, maybe add a set of three mast tubes to allow experimentation. Once a database of converted designs is collated (with your help thank you) then that information will become available too.

I have sailed the OPUS rig throughout 2009 including taking 2nd place at the 2009 Sheboygan Footy Fest which had a good competitive entry again last year, on it’s first serious outing. It is an easy rig to sail and easy to set up for good performance. I hope that you will enjoy it if you decide to give it a try. See http://www.scalesailing.com/product.htm

From the various Footy Forums and the AMYA magazine you would think that model yachting is all about the racing (and the rules). I believe that there is so much more to enjoy in model sailing than that. I do admit that when I race in a regatta I am competitive, I am trying to win without a doubt. But the vast majority of my time at the pond with a model yacht is spent sailing just for the sheer fun of it.

Kittiwake K2 kit number 284 just left the boatyard which proves to me that I am not the only one sailing for fun. Certainly Kittiwakes do turn up in race results and a good number of club footy fleets around the USA are full of Kittiwakes. However that still leaves the vast majority being sailed as simple fun boats, travel boats, kids project boats, family boats, hobby boats, retirement boats, in fact all of the really important kinda boats. Of which I am very pleased!

Ever heard of ‘windling’? Windling is a word invented by Mark Steele who writes the ‘Where the Winds Blow’ articles at ‘Duckworks Magazine’, see http://www.duckworksmagazine.com/¬†and specifically http://www.duckworksmagazine.com/08/columns/steele/index9.htm
Windling describes this sailing for fun attitude. Formerly the writer of ‘Windling World’, a self produced real paper magazine for many years. Mark now continues his wonderful writing online. Take a while to read his archived pages and I am sure that you will find great enjoyment and inspiration too.

So if you have just discovered Footys or model yachts in general please be assured that for the majority of us it is all about the pleasure of building and the fun of sailing quietly on our beautiful lakes. Racing is there if you want it and is enjoyable too, especially with Footys where the people actually running the regattas are intent on keeping it simple and fun. So build a Footy and join us, sailing just for the fun of it.

Yesterday evening Kittiwake K2 took to the water to try out the new sail plan. There was a good breeze coming and going which offered most of wind speed range I would expect this rig to be sailed in. I am pleased to report that everything looked good. I particularly like this sail plan which I first used on the Pond Sprite design. The main sail has a fair sized roach area which gives me more area low down (a good thing on a footy) without needing a longer boom. The shape holds nicely without any battens too. The larger area jib than the original Kittiwake helps keep the balance right and in the lighter winds K2 showed the expected (and desirable) gentle weather helm.

When the breeze got up K2 would luff up hard into wind, so I brought her in and added some twist to the main sail by loosening the kicking strap. The luffs were back under control then and a couple of clicks of rudder lee helm trim had K2 free sailing a tack very nicely. De-powering the main sail with the kicking strap tension will tame strong luffing in gusts on many boats. When that no longer works it is past time to switch to a smaller set of sails. Give that a try on your boat.

The carbon strip forestay did it’s job and will definitely be in the kit now. With just enough forestay tension to hold the jib pivot up, the carbon strip holds the luff edge of the jib straight and true.¬†A straight jib leading edge really improves the jib efficiency which is why bigger boats have a back stay to support the mast against the pull of a normal forestay.

Despite the larger sail area I would judge that K2 puts her bow under on the run less than the original Kittiwake. The battery is now located at the rear of the radio bay which clearly helps. Driving hard on a broad reach K2 seems to keep her bow up and transom down better too.

Overall K2 looks like a quick boat and I will be keen to race her against the fleet at the first opportunity. With this new carbon boom rig K2 will be faster ‘out of the box’ for those people who are racing Kittiwakes. For the fun sailor the rig will still work over a good wind speed range with a little lower top limit than the original Kittiwake sail plan. Of course the original sails will still be available for use on K2 as well as drawings for the class legal ‘B-rig’ for home construction.

OK it’s back to the workshop and get this kit together for you guys!

Happy sailing, Graham
