[Sonar] Fw: Another question about Sonar sailing equipment rules

I'd recommend the MicroCompass. The wind in the Midwest is too shifty
to utilize the RaceMaster. That compass is designed for offshore
sailing.
I use a MicroCompass all the time for scow racing. And I believe
Zataway has one rigged for her boat. Not sure who else is using it.
More importantly, a RaceMaster is $900, and the Micro is $450. Save the
money and spend a little time before each race going upwind. Record
heading ranges from each tack, and then write them down on a piece of
duck-tape stuck to the hull. That can be your reference for the rest of
the race.

Nice headline on sonar.org John!
Here is the response from Peter Galloway regarding the RaceMaster.
So
it turns out, we were all correct in a manner of speaking.
(the RaceMaster is the more advanced Tacktick that has the lift/header
windshift indications)
Actually I'm a little hesistant to go with a RaceMaster because it may
produce an information overload or context mismatch situation which can
cause more mistakes than it is intended to prevent...especially if the
skipper is on the steeper part of the learning curve as I am.
See below.

Re: Another question about Sonar sailing equipment rules
Tom,
We eliminated the restriction some years back. You may use a
sophisticated Tack-Tick if you wish to.

I have another question regarding Sonar sailing equipment.
Is a device such as the Tacktick Racemaster, with its windshift
indicators legal in the Sonar class? There is some discussion
between
two fleets anyways that the windshift reading version of the Tacktick is
illegal. While there is no issue with the digital compass itself,
the
issue is with some of the advanced features of some available models.
The class rules don't seem to state this specifically and I wanted to
get
a better interpretation.
Thanks.

Re: A question about Sonar sailing equipment rules
Tom,
Unfortunately, the boom kicker is not allowed.
The Sonar Class has "Closed" rules which basically means that if it is
not
specifically allowed in the rules, it is disallowed.
The boom kicker provides a significant advantage in light air as it
lifts
the boom allowing the upper leech of the main to open, thus it is a
speed
enhancing device.
I'm afraid you will have to use the main halyard or a backstay clip to
hold the boom up.
As for number 325, we have no record of it. Undoubtedly it was built by
DS
Yachts in Ontario, Canada. If you know who owns it, we would like to
include the owner in our data base.
Good luck.

Can I get an additional interpretation of the rules.
As indicated below, I'm interested in using a boomkicker as an
alternative to a topping lift or clip on the backstay for the boom to
hang.
A boomkicker does not replace or modify the boom vang, it is a support
for the boom. Here is a link to the website for an illustration:
http://www.boomkicker.com/Bk_index.htm
On the negative note, it can influence how the sail sets since it does
lift the boom when underway.
On the positive note, it does not modify or replace the vang in any
way
and does not affect the set of the sail if used properly.
I had used a boom kicker on a Flying Dutchman for several years which
assisted greatly in preventing broaches when on spinnaker reaches and
when
dropping/raising the main.
I know I asked the question earlier but I wanted to make sure that it
was
understood that the boomkicker is not a replacement or substitute for a
class permissible kicking strap. It would be considered additional
equipment.
We have someone in our fleet here who is potentially interested in Sonar
#325 which apparently you owned or at least sailed. There is some
discussion as who the builder was. Can you recall who it was if this
is
true?
Thanks.

Re: A question about Sonar sailing equipment rules
Tom,
We are a class with "closed" class rules. This means that if it is not
specifically mentioned as permissible in the class rules, if it is not,
subject to the Technical Committees interpretation.
Class rule F.8.4 (iv) states: "KIcking strap shall be wire, rope or a
combination of both."
Rule F.8.6 (l) states: "Kicking strap shall be of block and tackle
construction...."
A fiberglass device is not mentioned thus not allowed.
As for the mainsheet, class rule F.8.6 (d) states: "Mainsheet shall be
single ended with one cleat location." A fine tune is not allowed.

Peter:
I've got two questions:
1. Is the use of a boom kicker (a fiberglass device that holds up
the
boom that greatly assists in shorthanded sailing situations) legal per
the
racing equipment rules?
2. The use of the Harken dual exit mainsheet system with fine tune
built
in? I believe the total purchase on that is 3:1 for rough tune and
6:1
(total) for fine tune which seemingly fits the rule of no more than 3:1
for a fine tune. In this system, if you want 'rough' tune, trim
with
both lines....fine tune with one line. I presume that you're
familiar
with this system.
I am splashing a restored #23 this Wednesday into the Wayzata MN fleet.
That brings the total here up to 17 and #18 is soon to come.
Thanks!
