IOMICA Forum

Hi John

Thank you for your numerous contributions to Radio Sailing, including holding many executive positions in the CRYA and IRSA as well as your numerous rules and tactics discussions. Although your retirement from active sailing is understandable given your lengthy tenure, it comes as a loss to ...

Thank you Sean

Yes, please send me (or post a link to) the last few years' Treasurer's reports.

I think the general membership should have the right to evaluate the financial health of our organization in order to make informed decisions on how funds are spent.

Does IOMICA spend money on ...

Does IOMICA have the financial reserves to supplement the budget of WCR's to support video broadcasts?

To that end, I tried to find the Treasurer's reports from the last few AGM's but cannot find them on this website.

thanks again

Thanks for taking the time to respond. Would be easier in person over a pint.
Your logic maks sense although now we must define what "permanently fixed" means. Are fittings that are screwed into or threaded onto permanent?

Andrew - sorry to bother again but;

A.1.4 DEFINITIONS
Vang - Equipment connected to the boom and used to control the angle between the mast and the boom.

How do we determine what constitutes the "vang" and what constitutes the "vang fitting"? In our own definition we make no distinction between ...

thank you for the clarification

Andrew - I have another question concerning the VISS type vang:
If the current rules stipulate that ...the mast vang fitting and/or gooseneck...they shall not exceed 20 mm in any cross section perpendicular to the axis of rotation.

How does this arrangement comply? I did not place a ...

A sensible approach.

Watching the video feed of the current WCR, there were numerous mark contacts that did not seem to have a corresponding penalty turn.

Although RRS E6.5 specifies that protests be delivered to the protest committee within 10 minutes after the last boat finishes, the only ...

Although legal if not specifically excluded, use of video in protest hearings in troublesome to me.

We place Umpires in the control area and prohibit them from using binoculars so they observe the same scenario as the competitors.

We also require witnesses to be competitors in the same heat for ...

Have accumulated a couple of dozen A, B, and C rigs of various ages and conditions over the years but as I said, shipping from ID to VA will be more than they are worth.

In my private capacity I offer the following:

Since IOMICA has not specifically addressed the plate vang issue in the newest edition of the IOM Class Rules, one must refer back to IOM Class Rule F.2.3 which states:

"The function of items shall be limited to what is normally provided by items of ...

One could argue that the FRA proposition comes closer to the goal of limiting the surface area of these dual purpose vangs by establishing both a maximum X and Y dimension.

My questions are:
1) is this issue one that should be decided upon by the IOM owners or by our elected VC Tech?
2) does the ...

If the consensus is that a plate vang should be legal (a notion with which I disagree as it does not comply with F.2.3) then rather than specify a surface area limit which can be difficult to calculate, perhaps specifying maximum vertical and horizontal dimensions could make measurement less ...

Please take note of the fact that my comments are in my personal capacity as an IOM owner, not that of IRSA as I have noted before and is reflected in my signature

This is a complicated issue, particularly when it is being written to include the VISS vang.

An surface area measurement may be difficult for event measurers to calculate at pond side, and may not be accurate if measured while attached to the rig. Do we really need to make this more complicated ...

To Darrin's post - the notion of asking for an interpretation prior to putting a new design feature into the marketplace makes sense and should quell controversy but not all agree.

Recall that two contentious developments in recent IOM history have been the issue of moulded sails and the issue of ...

Thanks for being open to public discussion on this controversial topic. Opening up this forum is a step in the right direction. Social media is nice for photos etc but does not offer much in terms of keeping a substantive discussion in one place.

I fear that unless we clearly define the maximum ...

still good advice though

What happens when you are a manufacturer and VC Technical? Should that be where IRSA steps in to adjudicate?

in my private capacity, not as Chairman of IRSA

I have a few old rigs but the shipping would probably exceed their value inasmuch as the sails are worthless. Good source of parts & pieces.

I guess if a "deck" is undefined in the rules then any sort of unusual and unexplained protuberance could be considered legal eg. the bumps on the deck of a VISS

Section F rules concern rigs:

F.2.4 CONSTRUCTION
(a) Fittings and/or control lines may be combined provided their function is not ...

rules must be enforceable and therefore, structures that can only be examined by destructive testing (like the interior of a honeycomb structure) should not be allowed

lets not get into the rule that specifies what grades of aluminum are allowed

opens up a whole new area of creative "deck" components I guess

also opens up a whole new area of creative plate vangs that pass through the appropriate size ring

for a single rudder, probably most time/cost effective to simply shape one out of wood and veneer it with a single layer of light weight fiberglass

less throw = less drag
45 degrees seems a bit much and makes it tempting to use the whole throw, although it might be useful when trying to stop to avoid going over the starting line early!

If you're determined to use a switch, use a SmartSwitch from RMG - it is sealed, shows battery charge status at a glance, and is flat to eliminate line snags

Looks like it should be measured as additional sail area!

Some time ago, some boom vangs were quite large CF plates and they were outlawed along the same line of though

with LiPo or LiFe battery high capacity, it's probably easier and simpler to change batteries after a certain amount of time and simply have the boat turn on when you connect the battery and eliminate the switch since its just one more electronic thing to fail.

this assumes your battery is in an ...

What did you decide?

The rules pertaining to the "rig" state that material of any density is allowed below the "lower point", to allow counter weights to be placed onto or inside the spar to make all rigs the same weight (C.7.3 (a)).

The jib boom counterweight is not really a corrector weight ...
