Nah c'mon Mossy, you can't claim an upwind 180 as a roll tack. For it to be a roll tack there has to be a foot switch. I wouldn't claim it unless it was fully foiling either. It's a mistake otherwise.

A roll tack is a direction/sail change that utilizes kinetic movement to pump the sail by "rolling" as you come out on the new heading to create pressure on your propulsion sources (kite/sail/centerboard/foil/rudder) that generates apparent wind and therefore lift (speed). On a foil, it'd be damned near impossible NOT to use some roll for power as you did the maneuver, whereas in a dingy you have to use crew coordination and well-timed healing to get that same pump on the exit.

In racing the roll tack (facing the front of the board) is always used because it provides better upwind progress during the maneuver. Notice that you come out of the roll tack with a twist in your lines and then need to unspin your bar.
When learning don't even think about trying to stay up on the foil, just doing it on the surface is challenging enough.
Here is a roll tack.
