When you first launch, bear away and check out the finish line to see how it's favored. It will vary with the shifts, but this will be your only chance to get a reading.
Next, head out to the little cove above the starting line and check out the starboard tack wind headings at Mark 1. This will inform if you tack after rounding Mark 1 during the race, since you'll have some data points on whether you're headed or lifted.
Next, lock in your upwind sail settings. Go with an outhaul on the deep side, and then depower more with the vang and cunningham. You'll hit some light spots as you sail to the Boy Scout camp.
Wait for your five-minute gun and watch the fleets that are starting ahead of you. In particular, note which boat reaches the rocks that the Boy Scout point, and whether they cross ahead once they tack onto port.
Once your five-minute gun fires, figure out where on the line you need to start, such as that you're pointed at the beach of the Boy Scout camp. You should lift up the rocks at the point below. The amount of lift was greater when it was windier. (See diagram below.) Figuring out where on the line to be will require a bit of trial and error. It will be mid-line, so your linesight will be crucial. Note that this approach worked even though the right end of the starting line was further upwind... be patient since about 2/3 of the way to the left shore, the boats on your windward hip (when on starboard tack) will start to drop into you.
On your final approach to the line, ensure that your cunningham and vang are easily accessible while hiking on starboard.
Start to Mark 3
On the upwind legs, play your cunningham and vang so that you have the max power you can carry while keeping the boat flat and tellales straight back. One thing that was working well for me (at 180/185 pounds) was to aggressively pull on the vang as a puff hit. (Others, like Julian at 165 pounds, had to sheet out in the puffs.)
Since we're at 7000 feet altitude, it's easy to get winded on the long upwind to the Boy Scout camp. Hang in there!
The layline to Mark 3 was actually a bit before the rocks at the point, maybe 5 boatlengths prior. So, consider tacking before you reach the rocks so that you don't overstand. I'm not 100% sure of this, since Julian managed to plane over me, even though he went further. I'm unsure if this was to do with puffs reaching him first, or straight-line speed.
On the long port to Mark 3, bear away in the puffs maybe five degrees below the mark. Then head up to close hauled (no more than 5 degrees above Mark 3) in the light spots. This will keep you in the breeze longer. Keep your cunningham and vang handy, since you'll find yourself switching from depower to power-up modes.
There were never any righties on the way to Mark 3, so no need to do anything but come in on the port layline.
Start to Mark 4
Same as above, but go all the way to the rocks to stay on the lift as long as you can. Tack on the first rightie you get -- even if it's just a few boatlengths from the shore. Seems to work well. I did several tacks, once every 30 to 60 seconds, and more than most people, and it helped me pass a lot of boats. It's exhausting to do this at altitude, however.
When you're on starboard tack, approaching the shore with a boat to leeward of you, proactively say, "You tack". This does a few things: first, reassure your fellow sailor that they can tack when they want, which is good sportsmanship. Second, if they hit something, they can't protest you, since you already indicated that they had room to tack. Third, when they do tack, you can time your tack to exit right to leeward of them, and gas them on port.
Exit the left shore when Mark 4 is about 5-10 degrees off your bow when on port tack. This will let you utilize a rightie that will likely come through before you reach the mark. This is in contrast to the approach to Mark 3.
Marks 3/4 to Mark 1
In general, four downwind legs out of five, there was more breeze in the middle of the lake than close to the downwind left (north) shore. So, it paid to do a smooth jibe (typically an overhand jibe) and then go BTL while aiming just to the right of the island north of Mark 2.
While doing this, vary your course by no more than 5-10 degrees to get into puffs sooner and then soak down once you're in them.
Also, watch any boats that go in closer to shore. In one downwind leg, we saw boats gain by doing closer to the downwind left shore. In two other legs, boats closer to shore had an initial gain, which later petered out by the time they got to the island.
You can pass the island on either side. You need to give it around 3 boatlengths of clearance; look to the water to be sure.
Past the island, if it's light (5-6 knots), you'll want to favor the outside (downwind right) side to stay in more breeze. If it's windier (9-10 knots), still favor the outside, but keep an eye out for puffs rolling in off the shore that you can sail to and then bear away to soak down.
There's often a convergence of boats from multiple classes at Mark 1, so you must also keep your air clear while playing puffs and waves.
Just before the leeward mark, if you're outside boats from another class, slow way down. A Laser will accelerate on the upturn from downwind to close-hauled, as you pass through a beam reach and briefly hop onto a plane. But other boats will slow down as they turn since they are heavier and have less efficient foils.
A good rule of thumb is to ensure your bow is about three feet behind the other boat's aftmost point (transom or rudder). This should allow your bow to swing past them in case they do a wide rounding (highly likely). Or, if they round properly, it will keep you from running into them from behind.
Mark 1 to Mark 2
After rounding Mark 1, you'll have some decisions to make.
First, are you in bad air from a boat in another class? If so, get out of their bad air; their wind shadow is MUCH worse than a Laser's. If it's light (5-6 knots), perhaps you can reach off so you go left in more breeze. If it's winder (9-10 knots) and/or you're headed, perhaps a tack is the quickest way to clear your air.
In the absence of any bad air, then your typical ideal track from Mark 1 to 2 is, in light air, to go left initially to stay in more breeze, only tacking in a leftie on the final third of the beat. Of course, you'll need to find a lane to avoid wind shadows from other boats.
If it's windier, the ideal track is to go left initially, then start tacking on lefties (or if you aren't headed but see righties coming down the course) about one-third to halfway up the leg. You'll want to "ratchet" your way to the starboard layline by the final third of the beat. If you're not sure if you're headed or lifted, or in a neutral heading, stay to the right of boats around you. The wind can shift as much as 20 degrees from Mark 1 to 2 in windy (9-10 knots) conditions.
Mark 2 to Mark 7
This is the first reach. Initially, aim five degrees high of Mark 7, so you accelerate into more breeze in the lake's center. Once in this increased breeze, I like to steer an average course of about five degrees low of the mark, as you go up and down in the lulls and puffs.
On the final third of the leg, the wind will shift behind you -- this is the same geographic shift you see on the way to Boy Scout camp. At this point, you can steer up to Mark 7 and should be on a quick broad reach. At this same time, the waves will be bigger, and you might be able to get ahead by surfing on some waves.
As you approach Mark 7, get ready for a tight reach: outhaul to upwind position, vang to two block, cunningham stays off, board up a touch from its downwind position.
Mark 7 to Mark 8
You'll start off on a tight reach. Point above the island by a few boatlengths and/or sail OVER any slower boats in other classes. It doesn't matter if they're sailing too high -- if you go below them, you'll get stuck in their wind shadow doing three knots while your competitors are doing 10-12 knots.
Once you get over the island, bear away and power up your sail (ease outhaul and vang). In general, it seemed like puffs typically came from the downwind left side of the course above 70% of the time. Stay to the left of any other classes sailing downwind as you play the puffs. This will keep you out of their bad air, as well as inside at the final leeward mark.
Mark 2 to Mark 8
Let's back up and assume we're not going to the reach mark, but instead downwind to Mark 8.
In this case, start by pointing maybe 5-10 degrees right of the southern end of the starting line, which is restricted. This will get you into the stronger wind in the middle of the lake. Once in that, then point at the pin of the starting line as you play the puffs. Pass the starting line mark to port.
The next mark is the starting area mark; this is not restricted, so you can pass it to starboard, i.e., go north of it, if necessary.
The next mark is the finish mark. Pass this to port since the finish line is restricted. As mentioned above, favor the downwind left side of the leg to catch the predominant puffs, stay in clear air, and gain the outside.
Mark 8 to finish
You'll be in one of three tactical modes on this leg -- subject to avoiding bad air from other classes with huge wind shadows:
- Cover. In this case, it's good to sail on port to the right until your competition behind is about to round the leeward mark. At that point, tack to starboard. You'll end up dead upwind of them and can cover them either way.
- Split. If no one behind is at risk of catching you, then do the opposite of the boat ahead, in case you can get a puff they don't.
- Catch up. Default to going right (puffs tend to come from that side ~70% of the time), but look up the course to see which side has the predominant puffs, and go there, while staying out of bad air.
Sometimes you'll want to tack for the favored end of the finish, but doing so will put you in the bad air of another class. In that case, it's often better to favor clear air over finishing at the favored end.
Since Jim excelled on lakes, it seems natural to have a perpetual for him for one of the bigger lake regattas. There's already a perpetual trophy for the Stampede Regatta, so that leaves Huntington Lake. Anyways, something to noodle on.
