Steve,
How's the swift coming, haven't seen any pictures lately. I haven't had any
problems launching or dousing with the pole. I did change the spin block on
the top of the mast, and added a small piece of material about 3/16" thick to
the mast to keep the block off the mast. I found with pressure on the halyard,
the sheave in the block would otherwise jamb the rope against the mast creating
a great deal of friction. Now it sets and doused effortlessly. If the
attaching point on the mast head for the spin block protruded a little further
it would be great. Not sure of the lengths or diameters but I will measure the
next time I am at the lake.

Subject: Class Rules Opinions please
Guys,
I've been talking to Clive at CST re masts for Swifts over here. We are also
going to get the other spars from him ie spinnaker pole and boom.
Clive is very keen to change our pole launching system so the spin pole
retracts into a receiving sleeve a la I14 style. This has a couple of
advantages - smoother launches and no issues with point loads on the pole. The
question I have is that reading the class rules it specifies that the pole must
retract to 700mm of the stem. We would like the receiving pole to go out to
this dimension - this further minimises any bending that may occur.
What are peoples opinions? Is this breaching the rules or not?
Also what actual length are the poles in use and diameter?
Cheers,
Steve
nb the 14s allow this but it is specifically catered for in their rules
Class rule extract
a. The Spinnaker Pole shall be retractable to within 700mm (27 5/8 inches) of
the stem. The length from the AMP to the outer most extremity of the spar, when
the spar is fully extended shall not exceed 6.095m (240 inches).
