The Shift comes with a sticker with which you can cover the "illegal" information, but I guess the "must not be capable" phrase overrides that. Thanks for pointing out.

I didn't see that. It says it is static-cling, which I means it can be applied and removed at will. I'd like to get AlanD's opinion, though I think he already stated it:

From a former measurer's perspective:

Whilst I'm in favour of permitting digital compasses, I can see that a measurer will need to know the capability of every digital compass on the market, both currently and what's available in the future. I'd rather that the bullet is bitten and that everything is permitted or keep the status quo. Why make a rule that cannot be really policed?​

Pretty simple, just because you can't see it does not mean it is not capable. It is therefore illegal in my opinion. I'm not in any rush to change from my Silva compass and I dread the day when it dies and I need to switch to the newer dual numbered card.

That one does not appear to have any GPS in it, but it does have the ability to store a heading and show +/- degrees for lifts and headers. That would make me think it violates the "wind direction" wording of section (d) from the new rule.

(d) A compass or timing device must not be capable of displaying, delivering, transmitting, receiving, calculating, correlating or storing information about wind speed, wind direction, boat speed or boat position.


TackTick Micro Compass - Compass Unit Only

In competitive sailing, being able to react quickly to a change in wind conditions can mean the difference between finding yourself in the front of the pack or being the last ones back to the dock. The wireless Micro Compass by Raymarine can help you achieve that competitive advantage.

This waterproof, self-contained compass fits the bill for dinghies and sport boats. Large twin display with battery level indicator. A lithium battery works in conjunction with a small fixed solar panel, providing you with of 200 hours of autonomous use. Three choices of data display - compass heading, tactical compass scale and race countdown timer. Because headers and lifts are not displayed, most one design classes will allow this compass.

Key Features:

  • No wires or connections to make
  • Can show compass heading, tactical compass scale and a race countdown timer
  • Simple to set-up and use
  • Waterproof (submersible to 10m)
  • Shock Resistant
  • Lightweight only 153g (0.34lbs)
  • Ultra wide viewing angles
  • Battery level indicator
  • Precise to 1 degree
  • Easy to read large digits

Does anyone have any ideas about rigging the hikingstrap now that the rule has changed?

Can we mount the tac-tick on the mast? Or are we going to have to re-write the new rule to allow that?

Yes. There was a picture of a suggested setup included in the voting form, but that's gone offline now. It had the line going through the mounting holes of a 211 Mk I Clamcleat (similar to the traveller cleat), with a stopper knot or two to keep the cleat sliding on the line, and a shackle as an aft fairlead.

As noted before, the rule text isn't very specific. It doesn't clearly say if you can use the one allowed shackle to attach the cleat to a cockpit eye (which I would do), neither does it mention any characteristics of the cleat (built-in fairleads, rollers, etc?). Of course, some model of Clamcleat is a natural choice here, but I was thinking if a Spinlock might work as well?

Can we mount the tac-tick on the mast? Or are we going to have to re-write the new rule to allow that?
A compass (electronic or not) may still be mounted only on "any part of the deck or the cockpit". And it would make extremely little sense to mount one on a rotating mast anyway ;)

I have to disagree here, the Tac-Tick has two faces, so one should be visible from either gybe. My concern would be the Cunningham and outhaul fouling with it. However, a properly designed mast bracket would alleviate that.

A mast mount would benefit light air sailing.
Getting the compass off the deck would reclaim lost real-estate. Sitting in front of the dagger board would be much easier.

Mast mounting the compass would keep the daggarboard bungee clear! Also it would protect the compass from being knocked loose from Velcro mounts. The compass on the deck fouls easily with the vang tail attached to the dagger board too.

Does anyone recall why the rule was written to exclude mast brackets to begin with?

If you look at the last issue of The Laser Sailor you'll see a picture of the deck mounted/approved digital device. It's really very clean, clear of control lines and takes up no deck real estate.

Jecoolidge2, you're missing the whole point. Hint: you want the compass to tell what direction the bow is pointing... not the forward edge of the mast :rolleyes:

(Fun fact: I've actually seen someone do it - a German girl at a Youth Worlds a long time ago duct taped a big Silva with a mast bracket onto her Radial mast. She actually won that regatta, and went on to have a successful sailing career as an adult. Lesson learned: even the best sailors do very stupid things which no one should blindly copy.)

I don't know about you LaLi, but velcro-ing a compass to the Laser, is something I would not stand behind. ;)

What do you mean? That's how it has been done for ages. The velcro just has to support the weight of the assembly (should it turn upside down), and if that fails, the control lines keep it from separating from the boat.
That bracket looks actually pretty cool; as I said earlier, I'd prefer an offset mount to clear the centreboard elastic, which is never shown in pictures taken on land.

(Small correction: the girl I mentioned in post #31 didn't win the Youth Worlds, she finished third. Misread the awful WS result archives. Doesn't change the story though.)

Would the class rules allow for a gyroscopically-stablized self-tacking mast mount for your compass?

Seriously, I hope they come up with something similar to the white plastic spider. I’ve used it for 20 years with no trouble with my Silva/Nexus.

I believe that it's the same picture (the one with the yellow line) that is now on this page: New hiking strap support line rigging

I incorrectly remembered that the cleat was tied to the line; both pictured systems assume that just passing the line through the cleat screw holes creates enough friction to keep the cleat in place. (I'm not totally convinced.)

What I'd like to know is whether certain Clamcleat accessories are allowed... such as the bolt-on rope guide (would it count as the "ring" or a part of the cleat?):



Or an "Aero" base:

I am in the process of making mounts for the Tactic I will have a picture next week

That would be nice!

It seems to me that a compass that can be looked at hiking out from both sides of the boat (TackTick) would be preferable over the Nautalytics one.

The Nautalytics has a "viewing cone" of 120° (60° off the centreline) and the numbers are twice the size of those of the other alternative, so that's probably not a deciding factor. Would have to test them on the water. Simple Compass

What keeps the Nautalytics marginal in the near future is that no one outside the United States seems to be selling it. In contrast, I can go to several shops in my home town (Helsinki) and buy a Raymarine Micro off the shelf.

We are almost done testing camera mounts that have been approved by the chief measurer
