If you are racing under PHRF it is best to check the rating instructions
for your region. Below are the regions I race in:
In PHRF-NB (Narragansett Bay) the instruction states:
REPORTABLE ITEMS OR MODIFICATIONS:
R6) Rig modifications such as, but not limited to:
b. spinnaker/whisker poles exceeding 101% of the J dimension.
(this means you get penalized if a whisker pole exceeds the
J by a variable amount depending on how long the pole is)
For ECSA PHRF (Eastern Connecticut) the instruction states:
REPORTABLE ITEMS OR MODIFICATIONS:
Whisker Poles - Whisker poles must be declared, but there is no
whisker pole length (WPL) limit
For PHRF-NE (New England) the handicap instruction states:
8.11 The standard class handicap for a yacht of a particular design
assumes the following equipment, unless the yacht is handicapped in a
one-design configuration:
3. spinnaker pole (SPL) the same length as J; whisker poles
shall be the same length as J;
And further the Racing Rules address outriggers (which are Spinnaker and
Whisker poles) as:
50.3. Use of Outriggers
a. No sail shall be sheeted over or through an outrigger, except as
permitted in rule 50.3(b) or 50.3(c). An outrigger is any fitting or
other device so placed that it could exert outward pressure on a sheet
or sail at a point from which, with the boat upright, a vertical line
would fall outside the hull or deck. For the purpose of this rule,
bulwarks, rails and rubbing strakes are not part of the hull or deck and
the following are not outriggers: a bowsprit used to secure the tack of
a sail, a bumkin used to sheet the boom of a sail, or a boom of a boomed
headsail that requires no adjustment when tacking.
b. Any sail may be sheeted to or led above a boom that is regularly used
for a sail and is permanently attached to the mast from which the head
of the sail is set.
c. A headsail may be sheeted or attached at its clew to a spinnaker pole
or whisker pole, provided that a spinnaker is not set.

I race handicapped by PHRF Lake Ontario which has no rating
adjustment for whisker pole length. I picked
up a Forespar Line Control which goes out to 22', a fair bit for a
30' boat.
In light air, 4 knots TWS, setting the sails perpendicular to the
wind works as well as anything else I have tried.
That has the pole low at both ends, barely above the lifelines.
At a higher wind speed the common advise is to trim the genoa so the
wind flows around it as opposed to
it being a barn door. That will bring the pole back so it is more
perpendicular to the wind, usually the
inboard end up the mast a bit and the leach pointing into the wind. A
bit like trimming a spinnaker.
Forespar has a diagram here:

Not having the leech bouncing around helps. For me that means
adjusting the inboard end to get enough
down pressure.
For a genoa with a 21' LP I will use all 22' of whisker pole in light
air and about 18' in moderate air.
In heavier air I switch to the spin pole which is 14.5' ( oversized
and I take a penalty ). I can tell it is not optimal but works OK.

We race non-spinnaker class and a few years ago I got an
extendable whisker pole for the genoa. I am unsure about optimal
settings for pole height and length. I suspect it is sometimes
suboptimal because I have noticed some boats able to carry the
genoa poled out at much closer angles than I have achieved.
Presumably the optimal pole angle is near perpendicular to the
apparent wind. It seems that extending the pole flattens the
sail to some extent but I suspect it is more complicated than
that. Height I have no idea. Any general rules of thumb?
Related to this, the VMG chart I have from C&C has optimal VMG
downwind apparent angle of about 140-145? true. Are those
numbers +spinnaker, -spinnaker standard or -spinnaker wing on
wing with whisker pole? Thanks- Dave
