All I'll say is I love racing against sailors in tide who believe all that guff they're fed about there being no such advantage.

One day somebody will forget that idiots book about the tide being the same for everyone - it ain't, unless you're deep sea, it never has been never will be and I'm buggered if I'm going to explain it all again here.

If you want to go left, start early. If you want to go right, start late. (persistent shift, topography, tidal difference across course; all the usual stuff).

If it's shifty, start early, as you will gain on the pathfinder (and hence late starters) by tacking back and forth to stay on the lifted tack. The pathfinder have sail port only for 5 minutes through headers as well as lifts. However, you do have to have enough boat speed to get your nose out so you can start taking advantage of the shifts. If you're just stuck in a starboard lane then there's no benefit. 

If you're fast, and good at starting, go earlier. If you're slow or bad at starting, go late (less time spat out the back). 

If you see the pathfinder lift, bail out and start later. Similarly if we see the pathfinder get headed, sail down to him to get out of the gate sooner. Sail u wind on port, about 100-150 m ahead of pathfinder. When you get a header, gybe round and start. You should be starting just after the pathfinder gets headed, which puts you in a nice 'bulge' in the line and reduces the chance of a later starter rolling you.

Often the gate boat will continue after the pathfinder has been released. It's worth noting early in the regatta how good the gate boat is at holding a steady speed and course after release. 

Not sure I understand GRFi's "if tide is favourable, start early". If it's favourable, then it's favourable for everyone, and the pathfinder will be being swept upwind just as quickly as the early starters...

Depends what the wind is about to do, if there's a header due anytime soon then go early, if it looks like it's about to lift, then go late.

Or the tide, if it's favorable, go early, if it's not, go late.

We used to have gates starts in the early 80's 505 style, nothing like a well run Mike Mountifield gate start with the correct application of dan buoys and nanny boats, banging in early into a knock, quick tacking then over taking the gate boat watching a fleet of 200 boards struggling to get by.

When I was racing Raceboards we used gate starts for our Thursday night racing at the club for several years. Saved anybody having to do RO so we could all race. We just sent the pathfinder (third in the previous race but nobody did it consecutively) off on port (starting at the leeward mark) and the rest started astern of him. Numbers were small and windsurfers have always been pretty self sufficient from a safety POV so no need for a safety boat either (worst case scenario it wasn't much more than half a mile or so to walk back 'round the lake). Worked for us.......

But then how many adults ever practice anyway!

Launch just before 5 minute gun, finish, de-rig, in the bar.

Pretty sure they were using them earlier than that, but it wouldn't surprise me that the N12 class would have got there first.

I don't think Fireflies were the first to use gate starts, but certainly they were used in the late 60's for the nationals. 
They tend to skew the results - everyone was busy counting their finishing place, if it was 10, then one would slow up to be 11th - no-one wanted to be pathfinder!
