IOMICA Forum

World Sailing has published the new RRS for 2025-2028. It may be found at https://www.sailing.org/racingrules/ I have also written a summary of the changes that I think will affect Radio Sailing. The document may be found on my web site https://sites.google.com/site/johnsrcsailingrulesandtactics/ Re...

The vote on this is coming soon - if you like the current closed materials list for normal construction, and think that the motion to amend materials for 3d printed hulls should have been placed in the the line item D2.1.8 Thermoplastics then vote AGAINST this item. This motion is exactly the same a...

The vote on this is coming soon - interesting that no one has any comments so far.

This topic has been presented by CRO again for the 2022 General Meeting, basically the same motion that was defeated at the last General Meeting. It is a shame that the movers did not follow the suggestions offered here for a more acceptable approach - just modify the section on plastics, and leave ...

I urge all IOM 'certificated' owners to read this carefully before deciding how to vote when your National Authority polls you. Here are my thoughts on this proposal - This proposal - create a database - has major issues - first is confidentiality - a person's right to privacy of data -sending a per...

Hi Robert, It is disappointing that you would go back to square one and start the discussion all over when we seemed to have reached a consensus on this thread that many would support a change that left the current materials alone and just made the minimum of line item changes that would improve 3D ...

Hi Robert, My impression of that picture is that the 'honeycomb' is not a honeycomb, but an hexagonal pattern surface texture, and serves little difference than the picture with strips. From Wikipedia, (and I underlined the key piece) Honeycomb structures are natural or man-made structures that have...

HI Robert,

Thanks for the reference to the rule change, however, it is still not an issue, as gelcoat is a type of resin (permitted) and resin may be coloured. The other references such as use of fillers still apply.

John

Hi Robert, You wrote Your proposal is not solving following items, related to the "classic" moulded boats. According to the current IOM Class Rules: a) Gel coat is not listed. Is it permitted? b) Coloured pigment is not listed. Is it permitted? c) Is a filler made of resins with some filler (micro b...

The question of allowing glass fibre as an allowed material for thermoplastics could be achieved by a motion to reword D.2.1(a)(3) which says (3) Resin, which may be coloured and/or reinforced with glass fibres, but if it were changed around such as (3) Glass fibre. which may be bonded with resin, w...

I will start by saying that I am not knowledgeable abut 3D printing, but it seems to me that there are three elements to proposing a materials rule change for the class. First, a proposal for 3D printing should only apply to class rule D2.1(8) and not attempt to change the rest of the rule D2.1 rela...

Hi Sebastian, There is an item on the IOMICA Rules section about 3d Hulls http://www.iomclass.org/iom-questions-and-answers-qa-2/ and scroll to Thermoplastics. As I understand it, there is a discussion going on about additives in the pellets that may not be in the list of approved materials. This ma...

Hello Joseph.

You raise some good questions, but this forum is not an official channel for getting the correct and binding answers.

The correct process is for the Class Secretary of IOM-France to send your question to the IOMICA Technical Committee for an interpretation.

John

Hi David, it sounds like you are mixing up gate marks with offset marks. The purpose of a downwind gate is to allow the fleet to split between two marks and especially to break a cover and split tacks with a boat that is just ahead of you. The purpose of an offset mark is to separate the boats that ...

Hi John, The ARYA Race Management manual recommends a minimum of 5 boat lengths for the offset at the windward end, and a minimum of 8 boat lengths for the gate marks. I would add for the windward offset, that it be far enough away that a boat has cleared the windward mark before reaching the zone o...

I just read on the UK forum of another IOM sinking - it nose-dived and probably blew off a deck patch - filled and sank immediately. the boat was 'lost'. It strikes me that it would be a good idea if we were allowed to put flotation inside the hull - eg ping pong balls, or those inflated plastic pac...

I heard that the proposal above failed to pass. The proposal failed to achieve the required two thirds majority. The voting was In favour 7 - Against 6 - and 4 abstentions. Some 20 countries did not vote. The breakdown was In favour Croatia, Malta, Norway, USA, France, Germany, Turkey. Against New Z...

Hi Colin, There are many answers to this question. If you use an RMG winch then you can use 2S (2 cell) LiPo or LiFe batteries, as the RMG has a built-in voltage regulator that provides 5 or 6v to the Rx and rudder servo. LiPo 2S battery voltage is too high for normal Rx and standard servos. But if ...

Once you read this and its attachments, please contact your National Sailing Organization President to let them know your views - either for or against. Your President as your National Authority is being asked to vote on this proposal - and it looks like a single vote - all or nothing. I am posting ...

Hi Frank, A mast ram is a really important fitting on a modern IOM. Not only does the ram control bend in the lower half of the mast, it resists the forward force of the boom/gooseneck. If the boom/gooseneck is allowed to push froward, the boom rises and the twist in the upper main opens - this happ...

Hi John 2. How will discards and redress be handled for Part B of the event? Think it is up ti Judges: some can give an average on the regatta, some for the day and some just a place assigned. Personally, I would recommend average of qualification or finals depend on where redress is given Regards ...

Hi Zvonko, I think there are some topics missing from the procedures described in the pdf. How will points carry over from Part A to part B - it should be spelled out. There are several options in use including a) carry points over, b) all start at zero, c) start with points based on assigned place,...

Many of us followed the event through its web site http://www.iomwc2017.vrc-pierrelatte.com/ Results are here http://www.iomwc2017.vrc-pierrelatte.com/results/ Good personal log from the NZ crew and easy links to over 40 hours of video http://www.nzradioyachtingassociation.co.nz/our-boys-in-pierrela...

Bruce, is there a problem with the USA IOMNCA forum - it has given me a null page for the last two days - just a blank screen.

John

Especially when some of us 'Luddites' refuse to use Facebook.

The second proposal seeks to change the International Regulations for World and Continental Championships. The proposal is to remove the concentration on HMS as the regatta heat management and scoring system. What this is really about is another attempt to bring in the SHRS heat management system. L...
