[quoteIf you start at the end of the line, would you recommend a inmediate tack to port and once you have gained enough distance tack to starboard. By this time the fleet can be below you on a port tack and YOU have ROW. I have been debating about this, but I have not had a chance to do it yet.
Is this do-able? recomended for a low line start?

Well, sorry to be contrary, but I think you've got the tail wagging the dog. There is no single preferred starting tactic. Instead of following a predefined strategy, look at the course and decide where you want to be
after the start. Then come up with a plan that puts you there. For example, if there is more wind on the left side of the course, I'll try to start on starboard tack at the pin, so I can reach the breeze faster. If the wind is better on the right, I may start at the committee boat end so I'll be able to tack away early. If the course or line are significantly port favored, or if starting in a port oscillation, I may try to start on port tack and hope to cross the fleet. If things are even all around, then I'll just try to start in clear air, at speed, at the gun.
Define your strategy for the race first, and that will determine how you should start.
