I would be interested to hear about any other D2 specific techniques if any one can share
Hmmm... Of course railing upwind is the classic D2 point of sail that just feels
so good. Not so much a locked in position as on a raceboard with the upwind straps, for me I liken it more to flying a hull on a beach cat. It's all about finding the balance and subtle heel/toe pressure.
I also love running square with enough wind to make it challenging. A tip I picked up here (Chris249 I think) was to err on the leeward side with my foot positions and weight. It feels like frictionless skating in leather boots downhill on ice, the board sometimes accelerating down a little ramp away from my bodyweight nearly toppling me over backwards. I like to keep the mast track and my weight as far forward as I can control going square, the board stays flat and really trucks along. (I have no idea if this is actually faster or if this was the technique used by the top guys back in the day - I like the way it feels, and I have no-one to race, so what feels good it is!)
I use more centreboard reaching than I would have thought. Again it just feels better, less side slip more push forward, a little bit of lift to the windward rail.
... and yep, leeward strap broad reaching when the wind strength warrants it. For me that weight to leeward is needed to keep the board level or slightly windward rail up. I also think it has to be pretty windy to warrant using that strap, it's a bit of a safety crutch otherwise and I feel the board goes better with my weight a touch further forward very often. When first on the D2 I'd bear off and slip my foot back to that strap, which is reassuring for sure, however now I mostly use it only when I find my foot back there of it's own accord.
Last thing I can think off at the moment is when transitioning, moving around, gybing particularly, with one foot momentarily lifted and the other taking all my weight, (unless the centreboard is loaded up providing stability) I find myself putting the weighted foot across the board and centered (side to side) that way I can balance the board with heel to toe pressure as I flip the rig and step forward (or whatever). I can't say it's always totally successful though!
Dobbelman specific: There is less rocker than the Lechner. Upwind as the wind comes up rake the centreboard a touch to bring the nose up as the wind rises.
Fun. How goes the refurb?
