New RRS for 2025-2028 published

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.

Re: HULL MATERIALS....3D Printing. Croatian Motion.

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...

Re: HULL MATERIALS....3D Printing. Croatian Motion.

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.

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...

Re: 3D Printed Hull

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.

Re: Distance of windward separation mark

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 ...

Re: Distance of windward separation mark

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...

floatation

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...

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 ...
