2009 proposal changes interpretations questions
Poll Conduct
Which of the following rules changes do you support?
Please read the details below, before voting at the
poll
on the UK website.
If you reject all of these rules proposals, select
"none of the above." Voting for any specific rules proposals
constitutes voting *against* any proposals you do not select.
We will discuss the current descriptions and adjust until
maximum consensus is achieved
You may change your votes at any time. Announcements
will be made when descriptions are updated.
Advanced Cunningham/Downhaul
Current rule - The following enhancements to the factory design are allowed:
- Additional purchase may be created by putting a loop in the line, and turning around the becket in the cleat, and this loop, before passing through the cleat.
- Additional purchase and loose footing is allowed by turning the line around the boom eyestrap and fixing it to the main sail tack.
Deficiencies:
- The current system jams at the becket, and often does not ease simply by uncleating it.
- The crew must go into the center of the boat for the duration of the adjustment, in order to pull
directly downward and achieve a succssful cleating.
Proposal 1 - streamline only
- Allow the following three blocks to be added:
- One lashed to the cleat becket
- one inline between the cleat and the luff grommet
- and one lashed to the boom in the same location as the tack eyestrap
- Allow an extra block to be lashed to the mast below the cleat so the controll can be pulled and
auto-cleated in most directions.
Proposal 2 - split line
- Allow the cunningham to be split into two lines.
- One from the tack grommet, through the boom turning point, through the luff grommet, ending in a block.
- The second fixed to the cleat becket, running through the block on the end of the first line, then
running through the cleat.
- Allow an extra block to be lashed to the mast below the cleat so the controll can be pulled and
auto-cleated in most directions.
Advanced Outhaul
Current rule - Allows purchase to be added by turning between the boom fairlead and the
clew grommet multiple times.
Deficiencies:
- The system does not ease reliably simply by uncleating it.
- The system takes two hands to adjust due to the awkwardness of applying forward force from beside the
cleat, and due to jamming at the fairlead and clew.
Proposal 1 - cheapest
- Allow a block to be lashed to the aft end of the boom or the fairlead.
- Allow a block to be lashed to the boom forward of the cleat, and the control end lead through it to
enable automatic cleating with force perpendicular to the boom.
Proposal 2 - smoothest
- Allow a block to be lashed to the aft end of the boom or the fairlead.
- Allow a block to be lashed to the boom forward of the cleat, and the control end lead through it to
enable automatic cleating with force perpendicular to the boom.
- Allow aditional block or blocks to be added to the sail clew. Details to be added later.
Advanced Vang
Current rule - Purchase may be added by creating a tail extending from the becket on the cleat,
ending in a loop, and running the controll through this loop to double the system's purchase.
Deficiencies:
- Benefit of additional purchase is not fully realized due to friction.
- Loop wears out frequently
- Single line requirement makes system unnecessarily complicated to rig
Proposal: Streamline existing rule
- Allow current tail to be a second line
- Allow a block to be fixed to the end of the tail
Vang Cleat Replacement
Advanced Storage Forestay
Current rule - No rules restrict usage or configuration of the boat when not racing. As a result,
purchase systems may be used, but must be removed before a race begins, and may not be attached
until a race has ended.
Deficiencies:
- Acrobatics required to adjust rig tension on the water without a purchase system, or to
attach and detach such a system, are dangerous.
- They increase liklihood of capsize by putting weight at the bow for extended periods.
- They create situations where crews are likely to be trapped under a sail during a capsize
- Existing rule encourages competitors to compromise safety to improve performance
- Existing rule discourages inexperienced competitors from getting up to speed with rig tuning
Proposal: Storage forestay purchase
- Allow the storage forestay to be shortened
- Allow a high load block to be lashed to the end of the storage forestay
- Allow the following system:
- a line fixed to the U-bolt runs through the end of the forestay (or block), and has a
triple-block fixed to its end. The length of this line must be configured so that at its
maximum extension, the mast is stable and cannot fall.
- a triple-block with becket is fixed to the bow U-bolt
- a line runs from the u-bolt triple block, through the forestay triple-block, three times,
and towards the mast
- the line is tied to an elastic-cord that is fixed to the mast
- No cleats may be added
- The system must remain slack while racing
- The system may not be lead to a cleat while racing
- Note: Current rule that rig tension and rake may not be adjusted while racing remains in place
Discussion:
When not racing (defined by RRS as before the preparatory signal, or after crossing the
finish line), the line from the system may be lead to a spinnaker guy cleat. This system creates 12:1
purchase by doubling the 6:1 purchase given by the two triple-blocks. Tension changes are trivial by
pre-loading the rig with this system, and then placing the slack jib halyard in the desired position.
Rake adjustments are simplified indirectly by drastically reducing the time and complexity required to
ease the jib halyard. Rake adjustment still requires attaching the trapeze to the guy cleat becket as a
temporary shroud. This system avoids the need for sailors to put themselves in dangerous positions. It also
encourages newer sailors to experiment with rig tuning earlier in their careers.
