Hi, I have a quick question. Hope you can help me yet again.

I occasionally participate in club races in tthe 29erXX and given the club only has Lasers & Bytes in the Dinghy Open class thats mostly what I race against. Mostly sailing on my own, I find it difficult to hold the start line by backing the main or jib etc so trying alternate techniques to get the best start possible. The fact that the Lasers & Bytes just sit there pre-start isn't helping me in finding space to punch through but thats what I try to do. I go on a reach back & forth along the line pattern few boat lengths away from the start line, time my arrival and just as the others are crossing the line heat it up into clausehall and head towards the line. Most of the time I get stuck behind them etc.

What techniques work for you in similar situations? Thanks for your help.

How long are the start lines? How biased are they to one end or the other?

You might find that its well worth starting at the "wrong" end in clear wind, just so you can start at speed and get clear.

The other option is to identify the people who finish towards the back of the fleet, and make sure you start next to them! They will always leave more of a gap and be less aggressive on the start lines than those that finish at the front.

This is a similar problem to wrighty's ( http://www.yachtsandyachting.com/forum/forum_posts.asp?TID=3363&PN=3 - http://www.yachtsandyachting.com/forum/forum_posts.asp?TID=3 363&PN=3 )

Best advice, assuming a windward start is to do a port-hand flyer, ducking the whole starboard fleet if necessary. You'll be in clear air and get up to your max speed and height. By the time you reach the top mark, the Lasers will be long gone.

Just start on port; pop through a gap or duck the fleet and put the bow down.

A great way of slowing the 29er down by the line is sinking the transom, just don't overdo it!

Start line is very short. Course is small as well. Optimized to run 4 races in one afternoon. Good advice. Thanks

Yikes.. How did I miss that thread. Sorry for the repetition.

Will try it. I know this sure slows me down when I do it unintentionally.

Thanks for all the advice everyone. Something new to try next time.

The trouble with starting on port in a low standard fleet it that there's always boats on starboard starting late.

The conventional advice is to sail along well below the line on port and tack into a gap.

Another option for those whos priority is clean air is come in behind the front row on Starbord at the committee boat end with speed and be the first to tack onto Port for clean air.

you'd be lucky to get through the fleet though, remember, "a boat clear behind shall attempt to stay clear behind" so you cant barge through an invisible gap between all the lasers who are stuffing each other up.

I'd always start on port in planing conditions with that mix of boats if you're in a boat that just goes sideways when stopped. If you come hammering in on a reach on port under the slow or stopped lasers, you'll only need a gap of about a boat width and a half to get through. Even if it all goes wrong and there isn't a gap and you end up going behind the committee boat, the loss isn't that great as a tack back onto starboard and then onto port around the committee boat's bow and you're out into clear wind pretty quickly.
I used this technique quite a bit in club races in the B14, and it usually worked even though the wings made it over 10 feet wide! It does scare the laser sailors a bit though to see you heading for a gap they wouldn't be able to tack through

Just don't try it in a long boat .... it certainly wouldn't work for an FD as although almost as fast, it will take nearly twice as long to cover its own length as it's nearly twice as long as a 29er!!

a boat width and a half for me is more than a boat length, 7ft wide, 15ish ft long.

I'm not that good at maths, but even I can see the flaw in this calculation...

Surely a trusty pin end start is actually what you want?

We used to sail against a fleet of F/balls at Datchet, and basically were exactly the same speed to windward VMGwise.  They pointed higher, we went lower and quicker, so if we started with one on the leebow, we were stuffed.

Get the pin end start, and you can sail for the speed that your design likes, to maximise the grip you are getting from the daggerboard.

Of course this does leave you open if the wind lifts significantly - favouring the committee end starters, but the second major rule is always to tack and cross in front the moment that you think you can.  That takes a bit of b**ls and practice, but puts you into phase before all the boats trapped by each other....the other problem of sailing a boat that doesn't point or accelerate as fast as the slower boats around you.

Good luck though, let us jnow how you do....!!
