Hopefully at Jolly Up 10 in April 2012. I just need a judge, as it is not fair to lumber Arthur with that job again, and I am still working on improvements to my designs! It was put to one person, and they agreed at the time, but I will not keep them to that until they have fully considered the offer... Perhaps there was some variation in understanding the rules this time, I still think I was right, but doesn't everybody? Here are my PROVISIONAL rules for SLED 3, but they are up for DISCUSSION. The only change is to rule 5, and I have expanded on MY interpretation of it, as of 21 April 2012. 1. The judges decision is final. 2. Each kite must be made by the flyer. 3. Any materials may be used. 4. You may beg, borrow or steal the design that you use, but credit may be given for originality. The maximum length of the kite must be between than 48cm. and 52cm., about 18 7/8 inches and 20 1/2 inches for any imperialists, excluding tails. Any sticks used must not be longer than 104% of the sail AT THAT POINT, and must run from front to back: no spreaders, or it wouldn’t be a sled. They must also not extend beyond the sail, front or back.6. No sewing: only glue or sticky tape is permitted. 7. No cells, tubes, or double skins, etc., only a simple single layer sail is permitted. Keels must be separate, and attached to a bridle line, or they break this rule. 8. Tails (or drogues) are permitted, provided they are not used as a sneaky way to increase the sail area in violation of rule 5. 9. Notwithstanding any of the above, any kite not considered to be within the spirit of the competition may be excluded. 10. See rule 1. Interpretation of Rule 5: Maximum length: I want this to be from the most rearward point of the kite to the most forward.
Maximum stick length: This has been changed to allow curved spars, as in Ray Holland's Curved Spar Sled (see below).What it does NOT say is that the longest stick has to be as long as the kite, or that all sticks must be the same length, or how many sticks there can be, or that they must be parallel, or that they must be straight.If you refer to www.kiteguy.info/resources/sledbook.pdf you will find an excellent summary of sled design history. It is where I found the design that inspired the outer shape of my Sled 2 winning kite. There are a number of sleds in there that I would expect to conform with the above rules, as they are pretty basic sled designs. These are: Allison's Polymorphic (Flexible) Kite, the original sled. Ray Holland's Curved Spar Sled. American Sportsman Keeled Sled. Tom Lehane's Round Sled. PLEASE TAKE A LOOK before you consider your next winning design. If you have anything you wish to discuss/argue for/argue against/agree/disagree or suggest, then THIS is the place...

What we need now is a confirmation of the dates. I bet it will be 28/29 April when I am away. But one less for Dick to beat.

My thought would be that no stick should extend beyond the front or rear of the kite, therefore there is no protrusion of stick from the sail. this is my interpretation to your rule. anything shorter that stays within the length on the kite is acceptable. As I've not entered or seen any of the previous rounds I'm open to be corrected, so, thoughts/comments?

I did TRY to keep the rules simple, but every time I have to adjudicate on a different interpretation... Personally, I don't REALLY see any point in sticks extending beyond the sail, as it would add unnecessary weight to the kite, although it may move the CG a little, but to keep everyone happy I'll include it, but not tonight, probably tomorrow.

Don't forget, it's in less than two weeks, is yours ready?
We now have a judge, Norfolk Dick has declined Eric's latest offering, and decided to watch the rest of us make fools of ourselves...
See you at the Jolly Up!

Damnation. There I was already to make a hooded sled as mentioned in www.kiteguy.info/resources/sledbook.pdf and wanting to confirm the dimensions I pulled up the original patent only to find that the sledbook has the design all wrong and rather than having a separate hood piece at the front the hood is actually a double skin leading edge so a no go under the rules.

Further clarification of the rules required:
Is the length of the stick the shortest distance between the two ends when when mounted in the kite or the distance between the the two ends measured along the surface of the stick.
Ray Holland's Curved Spar Kite cited above as conforming to the rules complies with the former but not the latter as when mounted on the skin the stick does not protrude beyond the front and rear edges of the kite and is thus no longer than the kite, however when taken off and straightened the stick is longer than the length of the kite.

I just KNEW this was going to happen, I'm just surprised it has taken this long for it to be realised: I didn't see it soon enough, either, so I'm not blaming you My thoughts: 1. Does this sled actually work as well as expected? 2. How much longer would the curved spars need to be than straight ones? I've just done a quick check, and 5% of 500mm is 25mm, and that is a LOT of curve, the midpoint over 80mm away from the straight spar position Even 4% (20mm) gives a deviation of about 70mm If you want to use curved spars as described, I'll allow a maximum of 4% increase in length over the equivalent straight spar, but it must NOT extend beyond the edge of the sail. Unless anyone else has serious objections: I don't, and I'm hoping to do well (beat everyone!) again ;D ;D ;D No, I haven't offered Dick a bribe, and don't intend to, but that's not stopping anyone else from doing so I have modified the rules at the start of this thread.

I don't think that the version in the Sledbook would be legal anyway, as the rules state a 'simple single layer sail is permitted', and that is effectively two sails...

Isn't a curved spar a form of spreader?

Isn't a curved spar a form of spreader? No, 'cos it doesn't hold the sail open or flat, just changes its shape when it is filled with air...

SLED 3 competition At Jolly Up 10, 28 -29 April 2012 Rule changes at www.roy-martin.co.uk/SLED The judge will be Dick Abbs (Norfolk Dick)
I saw this on Face Book yesterday and HAD to laugh! This ‘Dick Abbs (Norfolk Dick)’ is known to me and I question the calibre of the judge! Calibre is probably the wrong word to use as he certainly is of more than sufficient calibre (in the nicest possible way) but wandering around naked is hardly something we wish to combine with our hobby of kiting and camping due to the amount of bending over involved, it hardly shows off kitings best side. Internationally he would be strung up, probably by the…..
I would further like to ask if he will be ‘breathalysed’ on the ‘morning after’ prior to judging anything, as he certainly puts the ‘Jolly’ into the Jolly Up!
I can only assume that there were no other distinguished, respected, senior, qualified, international, handsome judges available to attend such an important event, and hard choices had to made from the remnants, even to the point of heading up North to find someone?
Just edited my original post as it occurred to me that not all readers will know Dick or myself and what is meant as light hearted ‘banter’ could be mistaken for something more serious….GOOD LUCK Judge Dick, I bow to your superior knowledge to me in all things kiting but wish to advise you that judging peoples kites is the fastest way I have found to be the most popular person on the kite field one minute and then be left with just ONE friend and lots of grumpies the next! All I ever want to do is fly my (or someone else’s) kite!
;D ;D ;D ;D NO SLANDEROUS COMMENTS INTENDED TO ANYONE LIVING OR DEAD, ALL CHARACTERS MENTIONED ARE FICTITIOUS!
