In waves the most important thing for height is how you steer over the waves. In addition to this alot of club sailor neglect the fact that height comes from flow over the foils thereby fail to realise that to sail high you need to sail fast.

Pointing ... tight mainsail leach, a little outhaul off, flat jib entry, plumb upright, full board;

As has been said, if you crack off a little, you will reduce drag and sail faster, which may result in sailing higher.

Ref. Starting; look at some YouTube starting clips, the key is to pull the trigger at the right moment, and crack off to get speed in a space that you have created to leeward.

I wish I could practice what I preach!

It's about the maximising the lift to drag ratio, rather than minimising drag per se, but generally flatter sails would help point higher,  Pointing high isn't necessarily the best option though.

also limitations of  structure and /or class rules    may mean  that   a theoreticla optimum is either not achievable or has such as small 'groove' for a particular class that a less than optimum but #'wider groove' setup makes for  a better VMG

Exactly so. Any boat can point higher by flattening off the sails, sheeting ultra close and pinching up, but the end result is the entire fleet footing across your bows and leaving you in their dirty air.

Though always quite fun to have a National 12 when starting in a Handicap Fleet ...

There is definitely a place for having an effective high mode as it will really help you to manage your lane.

I so miss being able to pump like a b**tard whilst stuffing the arse out of it off the line until there's room to foot off into. #nofunstartingindinghies
