Peter’s advice is all good, but being klutzier than he is I find I need to tape it to ensure it stays square. If the conditions get rowdy, I seem to knock it at some point, and then no amount of friction tape or shim keeps it perfectly square.

Hi Tsharks,

Sure, the Button Fix does allow the potential of rotation if knocked. Maybe two button fixes would have solved that, however, if unnecessary, that would go against the RS Aero's design ethos of simplicity, lightness and minimising cost.

It is a simple attachment on a smooth part of deck so you may chose to add tightness (by padding out the bottom of the compass) or adding friction (a little non slip tape maybe) to be more secure and firm..

I cope with just using the button and bracket as they come, but I am conscious to get it square and not knock it. On a multi day event I might go to the trouble of adding tape to ensue the compass stays square - but adding to the underside of the bracket would provide a tidier solution.
 
[ NB - Regards the earlier part of this thread, the latest edition of the Class Rules C.5.1 (a) & (K) allowed more flexibility on where a compass and its mount may be located and how they may be attached ]

As a new owner of an Aero, I am revisiting this thread, not addressing a rule change, but looking further into the functionality of the current bracket. I can accept its location and thought process in design. However, its mounting function leaves very much to be desired. Using a " button-fix"  assembly which to me is designed for static panel attachment, is being used in a dynamic situation causing problems from the start.
Making certain I have the bracket fully engaged on the BF assy,  there is easy rotation in a dry fit and increases when sailing. I have added an edge molding to the bracket where I can, to provide friction and reduce any twist. It helps but is not a perfect fix.
In a training session, with a speed puck mounted to the bracket ($500 investment) I did a controlled jibe in waves and the bracket popped straight up at least 100mm before returning to the deck. Having a tether on the speed puck kept the assembly from sliding any further on the deck.
I am interested in knowing if there are any suggestions from Button-Fix or our sailors to make this assembly a more positive locking fit? 
Duct Tape, Really?? Can't buy that one. 
Looking for help.

Hi Marc
I am a volunteer and took on this role because I love of this fantastic boat and group of people. We carefully consider all comments and requests. We and RS are both proactive in trying to make appropriate changes that make the Aero a better boat to sail.

However, we are bound by our obligation of trust to maintain the philosophy and Spirit of the Class (this is set out in the Class Rules).

Perhaps you misunderstood my previous post. You can buy the female connector for the button for about USD2. You can make your own compass mount to attach to it (I have a homemade one, which I use). The only other cost of the actual compass. There are a number of twin screen options apart from the Tacktick, eg the Velocitek Prism. Also, the single screen one you referred to seems to be similar in price to the Tacktick. I offered a current solution if you want to move the position of your single screen compass forward of the button toward the mast.

Whether or not it is necessary to move the deck moulding is being investigated. We are very lucky that we have a considerate and responsive builder like RS.

Best wishes
David

David, thank you for your consideration and response.

Allowing a single compass to be mounted wherever one wants on deck does not materially affect fair sailing of the Aero, nor will it cause an undue financial hardship. In fact, the requirement to affix a compass at the stock location costs MORE, not less. One is essentially required to use a tacktick compass, which is over $400. Add the $200 manufacturer-supplied mount and we're talking $600+ tax/shipping for a compass on a $8500 boat. Talk about an "arms race"...
 
Moving the mounting point would require expensive re-tooling of the deck, a completely unnecessary reaction to a very reasonable, simple, easy-to-implement change to class rules.
 
Finally: Class rules already acknowledge the current mount's inability to properly locate a compass (by allowing tape to further secure it). Why all the effort to maintain a rule about something that doesn't properly perform its intended function?
 
It may be time to acknowledge that, despite the good-faith effort by the manufacturer, the compass mount use requirement is onerous and unnecessarily prescriptive. Again, the Laser class (which is extremely restrictive and moves at a *glacial* pace) allows such freedom--why can't we?

Hi everyone

This was one of the topics considered very carefully when the boat was being designed. As you appreciate, a basic philosophy of the class is it’s strict one design; we also want to avoid any arms race on equipment. Therefore, re this class rule:

You are free to make your own (or buy from a third party) a compass mount. That mounting bracket must be affixed (screwed or glued) to the female attachment (Part number RSM-HF-903 on the RS Parts website for £1.43 +VAT) or an equivalent. The female part can also be found on Amazon or elsewhere online. It is cheap. There will be stocks available in Weymouth. If you have trouble finding one, contact customer services at RS or your local dealer.

During racing the female part must be connected to the button on the deck. This was originally designed so that the location allows the vang rope to go through a hole in the mount, which saves the compass from going over the side if it comes loose). Merely tying a piece of rope to the button, or taping it to the deck or some other arrangement is not Class Rules compliant.

We are grateful for letting us know your concerns about the current location of the button and have raised it with RS. We will do some more research and talk to various people at the Worlds in Weymouth to see whether the button location should be moved forward. In the meantime, for Weymouth only, if you want to make a plate (a bit like Laser sailors use) attached at one end to the button and extending forward toward the mast (with the forward end being taped to the deck) we will allow this.

Happy sailing
David

Marc,
A tether is important if you have attached the compass with tape or Velcro.
My point is, subject to interpretation, you might not currently be restricted in the way you think you are.

Agreed ....that  IF it does not need locating on the button then it ought be able to be attached anywhere if tethering necessary, or not at all.....

Doesn't it seem a bit ridiculous to tie a piece of useless string to the bayonet just to meet the letter of the rule?

I was debating this issue with a new owner from the USA in Feb. Without official interpretation (it was the off season!) we came to the conclusion that 'attach to' does not limit where the compass is located and a thin tether can attach to the button as a safety line. The new wording of C.5.1(k) seems to support this conclusion.
An interpretation of  'attach to' is key. 
David, please confirm
 
In the version then (2017 V.1.1) the ability to attach with rope was questionable. In the latest version (2018 V.1.1) C.5.1(k) now allows attaching with 'rope..., shock cord, ....cable ties'  which is an evolvement.
 
'tape, ... , Velcro' are also included in C.5.1(k). So I presume sticky back Velcro is allowed? 
(Provided 'attachments...can be removed without damage to the boat'.)
David, please confirm
 
I like my standard RS Aero compass bracket. It is nicely designed and works well with my Tacktick micro compass. It is secured by the kicker/vang line and in the latest version of the class rules it has been clarified/permitted that any chance of movement can be removed by some tape or a little velcro stuck to the deck.

Hi Marc
 
 What flat/single-display digital compass do you want to use?

Plus one. I used the standard Tactic mount bracket and mounted it close to the mast just free of all the lines with adhesive tape. This works really well.

Even though I have a bracket attached to that little button, I too see no reason to require one to be located there. A workaround that appears to meet the letter of the rule is to just tie a safety string to the button from wherever the bracket is located.  A rules clarification might confirm this.

I also agree that the RS-supplied bracket is overpriced for what you get, and is not very resistant to rotating inadvertently.

I'd support a change to this rule.

I agree. There must be a way to word this rule to keep it tight but allow other brackets adhered to the deck further forward without piercing the deck.

This is a request to remove from RS Aero Class Rule C.5.1(a) the following:
 
"; the mounting bracket for the compass shall attach to the Originally Supplied bayonet attachment located between the mast and vang cleat"

The stock RS Aero compass mounting point has two big issues. It: 1) does not sufficiently secure the optional (and very expensive) manufacturer-supplied mounting bracket; 2) is too far back to effectively use a flat/single-display digital compass when sailing upwind due to off-axis viewing issues (virtually necessitating the use of the expensive, dual-display tacktick compass).

Even the Laser class, a notoriously restrictive one, permits mounting of a compass anywhere on deck, as long as the hull is not pierced. Does it not make sense to allow RS Aero sailors to do the same?

Many thanks in advance,
Marc Jacobi
