I would agree that the changing the number of boats moving will most likely have no effect on who the top 3 to 5 boats would be, but I think it does make a difference, say between top 10 to 20 in a full fleet, or top 5 to 10 in an example of our nationals. The difference between 14th and 17th might ...

Hi, Anders.
I'm using the XP 8103 (same radio, different marketing name) and used the Spektrum at our Nationals. Both antennae (tx and rx) were modified and had no problems at all. Had plenty of range problems before changing the antennae though.

It is interesting how common it is to hear about "being stuck" in the bottom heats, and how difficult it is to get out (and up). While this is true without question, one must realize that when moving more boats, it makes it easier to go down! :lol: I was a good example; I won my seeding heat to put ...

I missed it last time, won't miss it this time! See you there!

wings-yes, two rudders- no.

Course lay out: Distances? If you can't read the number it's too far away, thats the basic rule And here is where I think we need to draw our attention. Too many boats have illegible numbers. Although the previous identification rule was tedious (when the stroke was controlled), I believe it did a ...

A nice little quote from the skipper of the VO60 Movistar, in a report off Sailing Anarchy ( http://www.sailinganarchy.com/ )

"On the triangle not a lot happened , as expected just follow the leader"

Seems even the best of the best have the same opinions of triangle courses...

In my opinion it is a waste of time going down the road to eliminate the tube altogether. Bantock has been building his boats with it for over 5 years now, as well as at least a few other manufacturers since then, and that is simply too many boats to either change or grandfather. Restricting the tub...

If anyone were to think those were inappropriate, my suggestion for them would be to stop looking at them.
I say post them, he seems pretty happy.

Vacuum bagging is not the best method that I have found. A pressure mold is the preferred method for me, but if you are only looking to make one, it is a bunch of work. There have been successful fins made simply by using 2 metal plates, "wrapping" it around your fin layup, but I have not done this ...

I think the oval holes are legal based on the current rule, but does not meet the intent of the rule. Simply adding "and shall exit the hull within 2mm of the centerplane" to the existing rule will likely do the trick.

Semingly there seems to be general consensus that the oval holes don't break the rule as it is currently written? Has anybody worked out what the effects are of having such a system? The intent is to allow the tack to fall closer to the centerline of the boat, thus allowing the boat to point higher...

I was quite pleased with just about every aspect of the regatta, from the early preparations and assistance with travel and accomodations, right through the awards dinner. Their volunteer group was first rate, and I think we learned alot about umpiring (good and bad). The 2 biggest complaints I have...

As one of the Americans that voiced an opinion about the race course (imagine that, :lol: ), I can further say that it was not the distance that was the problem; it was the fact that we sailed directly away from us due to the triangle course. Bottom line: triangles don't work for radio sailing. One ...

Hello, Roy. I have always used rake as a regular adjustment. I have also asked many other top skippers about it, and it's about a split as to whether it is moved or not once the "right" balance has been acheived. In other words, there are some that find the "correct" rake, and then never adjust it i...

We've gone around already with what texalium is and isn't (two permitted building materials bound by an outsider other than the end builder, basically). It is not necessary to go through it again. It's time to decide if Texalium should or should not be permitted now that it has been interpreted as n...

And I think that the suggestion #2 would create a restriction that the current rules don't intend. Why shouldn't a skipper choose to raise or lower the entire rig for a given regatta, depending on anticipated conditions? Not much different from showing up for a regatta with a completely different A...

I guess what could be better clarified is whether or not the permitted maximum variation of 5 mm applies during an event. At the moment, this rule is a rule of Part C, which are rules that only apply "while racing". So does this mean that the height of a rig cannot vary by more than 5 mm while "act...

Interesting view.
If this is actually the case, Then 2 things should be changed:
1) the rule should be better clarified
2) these height numbers for each rig should be noted on the event measurement form. The way it is now, there is no way to show what it was when the boat was measured in.

I read the phrase "variation in X for each rig" to say that, taking each rig separately, X cannot vary by more than 5 mm, and do not read it as saying that each rig must be within 5 mm of X of each other. If 1x = 60, and 2x = 65, and 3x = 70, how can 1 and 3 be "within +/- 5? The rule is not clear ...

My interpretation of this has been that in no instance can any rig be +/- 5 mm from any other rig. If your #1 is 60, and your #3 is 70, that is +10, and is not legal.

I am a firm believer in black numbers on a white background. I have never seen numbers of any other color that were as easy to read, red clearly being the worst color of them all. Please..... use black numbering. It's the right thing to do.

Thanks for that info Anders. I was unaware of it. Their site makes it a very simple process.

Hi, Nick. I mentioned the skippers on the other side at Fleetwood as an extreme example, and I'm pretty sure that will not happen again. However, even having judges within the control area is showing inconsistencies. In Spain, there were so many "incident not observed calls" it led many of us wonder...

I think we have learned that proactive umpiring is not the way to go. In Fleetwood '02, there were umpires on the opposite side of the course. While this in itself is a separate issue, the principle remains the same: an umpire may not be aware that 2 skippers are communicating with one another. For ...

The ones I've seen are milled.

having aluminum as a keel fin and lead as ballast in the presence of water can cause the aluminum to corrode due to galvanic process. disimilar metals are not recommended to sit next to each other unless either is coated with dacromet. ed True, but in reality our boats spend very little time overal...

I think there is little aerodynamic difference between a large gap and a small one. As for the jib/main relationship, it either overlaps or it doesn't. Yes, a genoa makes the main more efficient. There is certainly a difference when the jib is forward or back, but the difference is the effort balanc...

Hello, Andrew. Welcome to the class! I would not recommend a pistol grip Tx. A simple 2 channel, 2 stick radio is fine to start with. I'll also point out that using a stock, standard sized servo is also fine to start with for steering. Later, as your skills progress, you may wish to have a stronger,...

Possibly, Roy.
I did carry on my Tx to Florida from CA just 2 months ago though. If there have been any changes, it's been recent.
