Amendment for OSR 2010
« on: December 11, 2009, 12:29:45 PM »
Looking through the OSR 2010, i've realized an important improvement ( at least for us ) see below:

 3.14.6 Lifeline Minimum Diameters, Required Materials, Specifications
a) Lifelines shall be of :
- stranded stainless steel wire or
- double-braided Dyneema® rope
b) The minimum diameter is specified in table 8 below.
c) Stainless steel lifelines shall be uncoated and used without closefitting
sleeving, however, temporary sleeving may be fitted provided
it is regularly removed for inspection.
d) When stainless wire is used, Grade 316 is recommended.
e) When Dyneema® is used, Grade SK75 or SK78 is recommended.
f) A taut lanyard of synthetic rope may be used to secure lifelines
provided the gap it closes does not exceed 100 mm (4 in). This
lanyard shall be replaced annually at a minimum.
g) All wire, fittings, anchorage points, fixtures and lanyards shall
comprise a lifeline enclosure system which has at all points at least
the breaking strength of the required lifeline wire.
TABLE 8
LOA minimum wire or rope diameter
under 8.5 m (28ft) 3 mm (1/8 in)
8.5m - 13 m 4 mm (5/32 in)
over 13 m (43 ft) 5 mm (3/16 in)


 As far as i remenber, textile lifelines weren't allowed last year...  Does anybody know if CM is going to add this change to the "Guide Mini" ( or is aware of it )

 Regards

 Pedro

 PD: Preliminary version of the 2010 Guide says   ( http://www.classemini.com/modules/kameleon/upload/Proposition_Textes_Guide_Mini_2010.pdf) :

 J-11-b-2: Les filières doivent être en cable d'acier 4mm minimum

The OSR was supposed to say single braid dyneema, ISAF is in the process of fixing the rule. No idea whether CM will allow dyneema lifelines.

Hello,

I don't know about the lifelines but I saw something else what was intersting.

New OSR: 3.29 - AIS Transponder
An AIS Transponder transmitting information from the yacht such as its position, speed and heading will be required for Category 1 and 2 races in addition to the existing requirement for Category 0 races.

Classemini Rule change: E-11 : addition of a note : AIS receivers and transponders, even integrated to the VHF set are forbidden*.

In the last year classemini was keen to keep up with the OSR. I wonder what happens to the AIS systems.

Bye

HI,

concerning AIS, it's still not allowed this year. It will be mandatory as a transmiter as from 2011 on the mini. Validated with FFV and ISAF. At least that was what was said at the AG in Paris.

Concerning the life line, I thougth in the Cm rules it was said it should be webbing... does it count as rope?

Bye

But a jackstay is not a life line (in French filiere ) but a Safety line isn't it? Safety lines are allowed if webbing... but filieres are always in 4mm steel aren't they?

Sorry I mixed both together....

During the AG no one asked this part to be removed from the 2010 rule. That mean only wire will be allowed. At least as I understand it.
