Is there a best angle or angle range to set the main mast? Mine is further forward than my dad's and I'm wondering how much difference it makes, besides how low the boom hangs.

As far aft as possible. Keeps the bows up and helps the boat point higher. Racers will rake aft to the max in most conditions.

How far aft you can rake depends on the type of mainsheet system you have.

You should be able to sheet enough for the wind conditions. Blocks should touch or nearly so when fully sheeted.

Is there a downside to raking, say on an H16? When does it become excessive?

Anything else one needs to tweak when doing this? Rudder, shrouds, travelers,..?

Excessive mast rake can create weather helm, which requires adjustment and/or redrilling of the rudders. I believe the newer 16 setups have shorter shrouds and longer shroud adjusters, since you need to shorten the shroud length to rake the mast as far back as the modern 16 racers do as compared to the original versions of the boat. I believe that the mast rake is more dramatic on asymmetrical hulls as compared with the symmetrical ones with daggerboards.

On older boats the mast step is more vertical. On newer boats they moved them to lean back further. I think you can get into some issues raking the mast back too far on the older boats.

Just keep an eye on the alignment and make sure there isn't any binding.

Great tips regarding the older boats, which we are sailing (H16). Occasionally a nacra 5.2 w/ daggers as well. Neither has been tuned up for some time.

We are a little overweighted at 160kg and don't use the traps yet.

Can you give any advice on how taught the shrouds and stays should be? They seem a bit slack. Would like to know how to set these and readjust during a sail, without a loose gauge.

I pretty much have perfect pitch, are there any notes I should be shooting for? ;-)

Shrouds are tension-ed by the jib halyard. They should be snug. There is no Loos gauge setting that I am aware of.
