IOMICA Forum

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 cumbers...

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? Add...

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 th...

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 surf...

Thanks for weighing in. It will be nice to see more interaction and communication with the EXEC on this forum - Facebook is nice but actual conversations on a Forum also have benefits.

Merry Christmas - looking forward to 2026!

Not trying to deflect, just trying to make clear to anyone reading this thread that the a vocal proponent of "double duty" vang arrangements that not only control the vertical lift of the boom but also add projected area, is also a major producer and retailer of these vang systems. This revelation m...

Do you have a vested interest in producing or selling vang/kicking strap/vang fittings that would be negatively affected if the projected area issue was resolved in favor of traditional simple wire/turnbuckle devices?

Thanks for the scathing rebuke - please know that I am not participating on this forum in my role as Chairman of IRSA, but rather simply an concerned IOM owner of 30+ years so kindly leave IRSA out of this. I have no ties to the manufacture or sale of these components, so I don't have a commercial i...

Thanks for your service. Please do not misinterpret my message: Now that both the resolutions regarding vang/kicking strap ring gauge measurement have failed, the rules concerning kicking strap/vangs are confusing. F.2.3 The function of items shall be limited to what is normally provided by items of...

Perhaps the new VC Tech could craft an emergency rule change/clarification that would makes vangs/kicking straps do what they were designed to do eg. control the upward movement of the boom and eliminate vangs/kicking straps from acting as unmeasured sail area. With the defeat of both the CRO and th...

I was able to see the voting results because one of the National Reps sent it to me - why not make the results available to the general membership also? Now that the CRO vang proposal has been defeated, what happens to the vangs on their boats that are no longer legal? Back in the Texalium days, the...

may we see the summary and results of the AGM recently completed please

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

Does anyone know where we can view the list of candidates running for election during this years' AGM?

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 extended...

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 eas...

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 (which...

no

It appears as though this discussion concerns how to allow "home builders" to use 3D technology for rapid prototyping. Since by all accounts, a 3D printed hull will be heavier for the same strength as a conventionally constructed hull, these will probably not be competitive but more as "trial horses...

I heard there is a WC Regatta underway, but can't find any mention of it on this site.

Bob Wells and I did an experiment using in-hull flotation bags. The text and underwater photos can be found on the IOMUSA.ORG website:
