Ahoi Fernando,
Admittedly, I have tried Petroleiro five times in this cold season alone... every time the screen shows me fish en masse. What happens then is a mystery: I drop onto the wreck and jig in vain. Next drop and the iron hooks into some railing or sueprstructure and I loose it. My irons alone should have decorated the wreck like a christmas tree by now. All day the fish see these gems dangling in front of their faces... so I understand now, that they just cannot be fooled anymore by the artificials... chchch.
I have been starting my whale watching there the past two weekends, so I had time to see the other two - five boats jigging over structure in the vicinity.
For what it's worth, I can see the point of the "vampires": It's easier to copy, than to invent and develop. But also copying takes talent, insight and respect for the creature to allow a sustainable harvest.
Just leaving port and trying to keep up with a boat with prooven success like SPEEDY... that's simply opportunism and will fail anyways, because SPEEDY is quicker than any other boat in the club but two.
Concerning the reefs and ledges, rocks and wrecks, I full subscribe to your anger: Everybody please find your own GPS spots and harvest sensibly. That takes time and will humble even the greediest "meat" makers in our clubs.
For the Marlin and Sailfish competitions I cannot understand, why giving away a position should be treason... the tides, currents, wind, rips and upwelling make such info obsolete within the hour given our current flowing at 2 to 3 knots.
I still just shake my head over the hopefulls, that wanted to play the copy game in Lobito on the third day of competition: We had 3 boats on our heels when leaving the Marina...
So we choose to stop at the first pod of dolfins and stop to take fotos...
That was considered a total waste of time and so our "shaddows" quickly went on their way... and we took off in our direction to find the rips and temp breaks of the past day...
Have a nice day, All.
