Try tacking an Asym in front of your stay on Lake Erie and you get a severe
caning !

11.6.2 Asymmetrical Spinnakers:
Asymmetrical spinnakers shall have the following characteristics:
11.6.2.1 Area no greater than a symmetrical spinnaker;
11.6.2.2 Luff and leech of unequal lengths where SLU/SLE ≥ 1.1
11.6.2.3 (SLU+SLE) / 2 ≤ 0.95 * √ (I2 +(the greater of J or SPL)2)
11.6.2.4 If the tack point is forward of the forestay, it must be reported
and appropriate penalties shall
apply (ref Spinnaker pole length penalties)
11.6.2.5 Adjustable leach lines are permitted in spinnakers, but may not
adjusted while racing.
11.6.2.6 ASMG is between 1.6 and 1.8 times the greater of J or SPL, and >=
75% of the foot length of the
sail where:
-ASMG - Asymmetrical Spinnaker Mid Girth - the distance between the
midpoints of luff and
leech measured in the shortest path on the surface of the sail.
-SF - foot length of spinnaker or asymmetrical spinnaker measured in a
straight line from clew to
clew or tack to clew

Mike, Bill �C 
Here’s an excerpt I was given from LMPHRF:


 Handicapping Spinnakers 2009 
*       Both symmetrical and asymmetrical spinnakers are allowed and both
may be used while racing. 
*       LMPHRF assumes spinnakers are tacked to a spinnaker pole, prod,
bowsprit or are tacked to the centerline at the stem. 
*       A spinnaker may be tacked up to a maximum of 12” in front of the
stem on a bowsprit without penalty. Using a symmetrical or an asymmetrical
spinnaker falling within measured dimensions provides for no penalty. A
distance handicap penalty of �\3 sec/nm may be assessed. 
*       Basic dimensions for an asymmetrical spinnaker are such that the mid
girth is greater than or equal to 55% up to 75% of the foot for a code 0
sail. If over 75% of the foot, the area of the sail cannot exceed the area
of largest symmetric spinnaker. 
*       When an asymmetrical spinnaker is the only spinnaker and is attached
to a prod/sprit, it may be 125% �\ 135% of the area of the symmetrical
spinnaker without penalty. A �\3 sec/nm distance handicap penalty may be
assessed. 
*       When both an asymmetrical spinnaker on a prod/sprit is used with
symmetric spinnakers on a pole while racing, a �\3 or �\6 sec/nm penalty may
be is assessed on a case by case basis. A �\3 sec/nm penalty is assessed for
each 6% or fraction thereof exceeding any production standard. 
*       Headsails that are under 55% of the foot at midgirth are jibs and
over 55% are spinnakers (ORCi 2009 rules). 
*       Headsails are commonly referred to as Code 0 spinnakers if they fall
between 55% and 75% of the foot at midgirth. Code 0 sails must be declared
and may be penalized on a case�\by�\case basis because they can provide a
significant advantage for some boats that use them, defeating the intent of
the US PHRF and LMPHRF Rules. 
*       Typical penalties are �\3 sec/nm for a masthead rig with a 155% LP
Genoa and �\6 to �\9 sec/nm for a fractional rig with a masthead spinnaker
and 107% LP jib. Penalties vary with the actual rig and how the sail is set
while racing.

Ditto, I was thinking of adding a long bow roller for this  hoping no one
would notice, 8^ )  but when brought up b4 PHRFLE I think they said it would
be their standard 6 sec.

CAn you send to me or list a link to your PHRF area rule on this?  We are
looking at this question in Nova Scotia where it is not currently well
defined.

Hi all, 

My winter project this year is to install a deck mounted bowsprit and fly an
asymmetric spinnaker while racing.

I am going for the max length with out a PHRF penalty, which in our YRA is
24% of J. This will give me a sprit that is 42.6 inches.

This decision is driven by a couple things. First, the ability to get 7 or
more experienced crew to manage the Symmetrical spinnaker. And to reduce the
overall complexity in sailing the boat. 

I am wondering if any one else has made this switch and what their
experience has been.

I will certainly share my experience.

Best,

Eric
