505 Tactics
Getting Around the Race Course With Other 505s
Some things to consider for racing a 505... This is a work

In fairness, I should point out before you read this, that
I am not renowned in the 505 class for my tactics, however I have been known to pass a
boat or two...
Some sailors in slower classes claim the 505 is a
"speed" class, with little emphasis on tactics. Those more familiar with the 505
know this could not be further from the truth. In a 505, and in some other high
performance classes, you have to have speed and pointing similar to the bulk of the fleet
to be a player, but once you do, the racing is very tactical. The tactics do get easier if
you are going faster than your competitors.
While the tactical principles are similar in all sailboats,
the relative importance of keeping your air clear, speed versus pointing, being inside at
the leeward mark, etc. varies with the characteristics of the class, the sailing
conditions, and the performance of the boat.
The Start
Whether it is a line start or a gate start, remember that
the 505 accelerates extremely quickly, except in very light air, so you can sit close to
the line and wait. Those hanging too far back will find that they cannot get up to speed
in disturbed air, and are left in the second or third row. The rapid acceleration and
extreme manouverability of the 505 mean that you will be playing the starting game at very
high speed. A port approach - for a line start - can work well, as the 505 can be up to
speed within a very few seconds of a tack. You can start tacking below a starboard tack
505 with ten seconds to go, and easily be up to speed for the start.
In light air, the 505 does not increase speed through the
water much when footing, but it does in any breeze. If a boat to windward is threatening
to drive over you, and you cannot sqeeze them off, foot slightly to gain separation and
clear air. Once ahead of abeam, go back to point mode.
The 505 can also point high - pinch if need be - to climb
off a boat to leeward. Just squeeze up a little to gain height, and come back down to
close hauled before losing too much way. You can scallop up provided you do not
lose too much speed. Sheet the jib harder and tighten the vang to help do this. Work up
just enough to be out of disturbed air, then get back up to full speed.
Windward Mark
Don't join the layline parade if you can avoid it! High
performance boats are slowed a much greater percentage of their speed when blanketed or
suffering from backwind than slower boats. It is much more important to keep your air
clear. Often boats that get into the starboard layline for the windward mark parade too
soon, suffer, as they are slowed by disturbed air and wake. As they are slowed, gaps open
between them and the boats ahead and astern, often allowing a port tacker an opportunity
to join the layline parade much closer to the mark. 505s also have a fairly wide range of
good angles to sail upwind, so crossing through the layline crowd and tacking above the
layline in clear air, then footing to the mark can work well particularly in planing
upwind conditions. Setting up above the starboard tack layline also puts you above your
nearest competitors as you hoist the spinnaker for the first reach, so you can start the
reach in the passing lane.
Spinnaker Hoist
While the vast majority of the time you will hoist the
spinnaker for the first reach immediately after rounding the windward mark, do not do so
blindly, once in awhile the reach will be too tight to carry effectively, or there will be
lots of traffic around you that would warrant you two sail reaching high for a few lengths
to get above the crowd. As anywhere else on the course, keeping your air clear is more
important with a high performance boat than with slower boats, if there is any traffic
nearby, you must get into the passing lane and stay high. If you are rolled by one boat
astern of you, you could easily be rolled by following boats as you never get back up to
speed.
Eyeball the reach angle and consider windshifts on the beat
before you get to the mark to determine if you will hoist or not. If in doubt, whip it
out! You can go part way down the reach, then douse the spinnaker and two sail reach
up to the mark. If you only have to go high for a short distance, you can simply uncleat
the spinnaker halyard, not bother dousing, reach up, and then bear off and rehoist.
There are two approaches to the hoist that will keep you in
the passing lane:
-
Hoist Immediately - if you are confident that you can hoist
quickly, get the crew on the wire and go high and fast, without the boat astern rolling
you, go ahead and do it.
-
Go High First - if in doubt of the former succeeding, go
high for a few lengths first, then bear off, hoist, get organized, and go high with the
kite.
If you are in traffic there really isn't much of a middle
ground. If you half heartedly reach up, and then hoist, the boat astern of you can two
sail reach over you, or simply get a better hoist and roll you. If you are going to hoist
now, you MUST do it as quickly as possible (you have been practicing, right?). If not, go
high to get at least a couple of boatlengths above the boats that do not go high, and do
not bear off to hoist while someone is close astern of you two sail reaching.
Keep your air clear for most of the reach, unless the reach
is too broad. On a normal reach you can change from "stay high" mode to
"get down to the mark" mode as you approach the gybe mark. If the reach is
broader than it should be, and people have to work lower to get down to the gybe mark
consider the following:
-
Curse the RC for not setting a proper 60 degree gybe angle
reach... :-)
-
Provided no one is directly astern threatening your air,
start working lower, or
-
Stay high with speed, and plan on gybing well above the gybe
mark, and reaching past it after gybing. If the second reach is too broad, consider
reaching past the gybe mark without gybing. No one is forcing you to sail a slow downwind
angle, you can choose what is the fastest angle downwind.
-
Go low immediately after hoisting, taking the pain of
disturbed air for awhile, to get separation from the fleet. This WILL NOT WORK if the
reach is tight. It has to be broad enough that the boats that go high are slowed as they
bear off down to the gybe mark, you can get enough separation and some clear air down the
reach, and come up to the gybe mark late, and at your fastest angle.
Gybe Marks:
If you were alone on the race course, you might do a smooth
gybe that did not slow the boat down, and minimized the distance sailed, but... YOU ARE
NOT ALONE ON THE RACE COURSE. Get in the habit of coming out of the gybe mark high, so you
protect yourself against boats astern, and set up to pass those ahead.
I try to gybe so I come out of the gybe closer to the mark
than when I start the gybe - it is SO important to come out of the gybe high and in the
passing lane. Perhaps the easiest way to think about it is that you want to gybe slightly
early, so you approach pointing a boat length or so above the mark - leaving room for your
boom, and exit the gybe next to the mark.
If in traffic, hike hard and sail as high as you can while
the crew gets the pole on the mast (you could also acquire a pole launcher to speed this
move up). A half a boat length of height at the mark could be worth lots of distance and
boats later down the reach!
Leeward Mark:
A leeward mark in traffic presents some challenges. You
want to be above and inside the boats near you, and must fight off boats trying to overlap
you to weather. Do not let yourself be pinned outside someone, better to put the board
down and douse a boatlength early to slip back, and allow yourself the opportunity to
round directly astern - or even a little inside - rather than pinned outside.
You must practice your spinnaker douse until you can do it
well repeatedly, and know instinctively how close to the mark you can come and still have
time to douse. You may have to carry it a little later than normal to fight off an
overlap, but remember that you are better off rounding ready to sail fast upwind with
someone inside you than you are rounding with no one inside, and the spinnaker only partly
doused! If you are not threatened, take down slightly early to ensure a good rounding, and
that you are pointing high and up to full speed upwind as soon as you have rounded.
If you are having problems with the douse or setting up the
boat REMEMBER to round the mark and point the boat upwind! You are better off going slowly
toward the windward mark, than sailing away from it while trying to complete the douse.
Try to come out of the leeward mark rounding as high as
possible. If you can make a smooth turn and flatten the boat as you turn, you can luff up
higher for a few moments so as to be slightly above the line of boats ahead or astern.
This tactic may also force a trailing boat to bear off below you to avoid hitting your
transom, putting them in your disturbed air. This can be accomplished by steering the boat
at a point a boatlength or two below the mark, and then not turning too fast. You want to
be close hauled as you pass the mark.
If you are trailing a boat, force them to carry their
spinnaker too close to the mark, and hope they flub the douse and rounding. With a good
douse and rounding, you can sheet in and sail right through their lee, while they are
completing the manouver and have not set the jib or main properly. Even if you cannot pull
of that move, you may be able to tack away immediately, before they are ready to tack and
cover.
I believe you can live with a slack vang for a few moments
- pulling the bridle mainsheet hard controls the leech, but that having the jib too tight
or too loose would prevent you from getting up to speed after the rounding.
Giving away distance at the leeward mark is probably the
most frequent mistake I see on the race course.
The Run
A set of polar diagrams for a 505 would be fascinating. The
optimum angle to sail downwind would have to change whenever the wind speed increased or
decreased by a knot, and also depending on local wave conditions. Continuously judge your
angles and speed relative to competitors to try to get the optimum angle and speed
combination for the conditions at that moment.
In very light air, sailing quite high to keep flow over the
spinnaker can work quite well. As the air goes from very light to light, sailing low can
work very well. You can even sail by the lee with the board right up to slide down to a
mark. Somewhere above 15 knots or so, sailing high angles to get the boat planing fast
becomes effective, and in big breeze, the top sailors are usually going down the run with
the crew on the wire and the skipper fully hiked. The fastest angle may be almost as high
as the reaches! Practice your run-to-run gybe technique till it is smooth, and then be
prepared to gybe for any puffs, angle changes (and even wave patterns in light air). Puffs
are key, the difference in boat speed due to a puff is quite significant.
In many conditions, pumping on waves is VERY effective.
Work on your pumping technique and timing, as badly done pumping is quite a bit worse than
no pumping at all.
The medium sized flatter spinnakers optimized for reaching
do not seem to go as low as the fuller spinnakers, so you may not be able to sail the same
optimum angle as competitors near you.
Much as pointing higher upwind is a big advantage, being
able to work low of competitors while maintaining speed can be devastating on the run. My
crew and I often sit astride the centerboard trunk - motorcycle seat style - as we can
lean to one side or the other to steer and balance out the helm, and the slightest puff or
shift is more easily noticed.
Leeward Mark End of The Run
Set up to be inside other boats as you approach the mark.
On port gybe, cut behind starboard gybe boats - if you cannot cross them - then bear off
and gybe on the layline, or close to it. In a spinnaker bag 505, remember that the douse
in the windward bag, followed by a gybe and rounding the mark, may be one of the more
difficult moves to pull off. A launcher boat does not have to worry as much about this
manouver, but often has the skipper steering with knees or foot, while dousing the
spinnaker.
In a bag boat, if you set up so that you can gybe to port
just a little before the mark, you can do a "gybe-douse", gybing the boat, not
rotating the chute, and leaving it no the windward side for an immediate douse. If you are
sailing a 505 worlds course, with a beat, two more reaches and a final beat after the run,
you should try hard to get the spinnaker down into the port bag by approaching the leeward
mark on port, or using the gybe-douse manouver. You would prefer not to have to do a
windward hoist, or throw-set, on a tight reach!
