Keep us in the loop with your results and conclusions.... We don't get much
heavy weather around here, but the few times we do, it would be very
interesting to have a sail combination which would let the boat perform like it
should. Is your inboard track on the deck or the side of the cabin? How far
inboard of the shrouds? How long? I have thought that my number 3 (working jib)
might work inside the shrouds, but it is just a little too big - it has a high
clew which ends up right at the shrouds when sheeted to my track which is about
three feet behind the shrouds and on the same plane.
I could cut it down a little and see - but wouldn't spend the money unless I
was reasonably sure it would work. We don't get enough days with that much wind
to spend a lot of time experimenting.

I have been experimenting with non-overlapping head sails on my 30-1. A
pinstop track was
placed inboard and back of the shrouds. I took a guess that a sheeting angle
of 8 - 10 degrees
was a tight as would work on a heavy boat and a picked a higher clew so that
the sheet loads
would not be too much. Martin from Somerset Sails recut a main to make a #3
and made a
custom blade. Both Dacron, nothing fancy.
The #3 has a soft entry ( a bit rounded ) even with full backstay tension.
The blade is flat with a fine entry.
The #3 points OK and is forgiving, the blade points very well but needs to be
kept in a narrow angle band to perform.
There is not much guidance I could find on the internet as to what to expect.
Starting about 16 kts true the #3 is the fastest sail on the boat,
outperforms the 155% North 3DL,
the 155% UK carbon tape drive and the UK #2 for speed. I can point as high
as 30 degrees AWA
with most of the sails, the #3 likes about 32 degrees AWA. The #3 runs well
to around 22 kt with a
full main. Around 22 - 25 kts true we add a reef to the main and switch to
the blade.
I can hold 6.4 kts upwind with the #3, seen 6.7 a few times. Boat feels
perfectly balanced, and the
#3 and main work well together. Still playing with the trim, best angle for
VMG etc.
Not as much experience with the blade, 24 kts+ and light waves are not a
common combination in
the Toronto area. The one time out with around 28 kts the blade and a reefed
main gave a perfect
sail plan. Just the right amount of power, stayed upright and balanced. Boats
with too much sail
were heeled way over and sliding off the course, and smaller ( baggy ) sails
were giving the skippers
poor upwind performance.
No conclusions yet on the appropriateness of inboard tracks and
non-overlapping sails on the 30-1,
but the trials are promising. I am considering getting a custom #3 cut that
is as large as possible,
maybe in the 102 -104% range, and enough depth to work in the 14+ TWS range.
Hopefully the
tighter sheeting angle and better matching with the main will overcome the
smaller size.

For most of your racing, you will use the racing main and the 135 or 155. I
seldom use my working jib but we don't get a lot of heavy weather around here.
Keep the standard main for practice. You may be trying to flatten it out too
much....a genoa will produce a backwind which makes the main look terrible, but
that is usual on a 30.
You should sheet your 135 and 155's to the track near the winch. My boat
didn't have any jib tracks when I got her, and I added a track which starts
about a foot behind the shrouds (even with them) and is about 6 feet long. My
sheeting point for the 155 is roughly in the middle of the lifeline gate, for
my 140+/- it is at the front of the gate. The working jib goes just past the
shrouds and I sheet it so that the clew just hits the shrouds. I seldom use it.
Many 30's just used snatch blocks on the rail for jib sheets, but you need
something inside that, which your track should handle.
When reaching, I use various methods to get the jib clew more outboard than
my track will allow - I have spinnaker twings (tweakers) ( small blocks in
about the middle of the boat on the rail ) which I can use to get the clew back
out to the rail. If it is blowing a bit, I have used snatch blocks to the rail
- you have to get the clew more outboard or it just becomes big and round and
slows the boat down.
I have the spinnaker pole and an adjustable whisker pole, but seldom use
the whisker - the rules penalize you for anything longer than 13.5 feet (the J
measurement) and the spin pole is that long.
Also the rules penalize anything bigger than 155%, so the 170 is only good
for cruising. If your rules allow larger genoas or longer poles, then you could
use the 170 and an extended whisker pole and sail non spinnaker.
Check your PHRF rules - one of our groups allows you to sail non-spinnaker
with the rest of the fleet and get a 10% handicap adjustment. I don't think
that is enough. Our other local group allows non-spinnaker with a 15%
adjustment and a cruising chute tacked to the bow with 7.5%. Nobody allows
genoas larger than 155% without penalty.
My opinion is the 30 would not benefit from having inboard tracks for the
small jib. The boat is kind of fat (10 foot beam) and running the jib past the
shrouds on the outside gives a sheeting angle of about 10-12 degrees, which is
about all it needs. As I don't sail in heavy weather very often (my working jib
is still 'krinkly' after 30 years) so I may be wrong - as your previous owner
built an adjustable little jib, you may have different conditions.
I also only have a single reef, but the boat was built for two - again, I
don't seem to need it.
If I were you, I would start by sailing non-spinnaker and find a crew and
develop your crew work. Then add the spinnaker to the mix. Learning the racing
rules and tactics and changing sails and flying the spinnaker is a lot to
absorb in a limited time. I don't know where you sail and don't know how many
opportunities you have to race, but there is more to learn than there is time
for most of us. Find someone who has some experience to help - pick his/her
brain to build your skills. Maybe let someone else drive so you can learn the
skills that each person on the boat needs to you can coach other crew later.
