Left the marina at 9 am and cruised about 1.5 hour to the point.  Set a lure spread and troll for 1 hour.  The tide was extremely slow.  It didn’t seem like a day for marlin and then, quit trolling.  The guest was enjoying catching mahi-mahi, tuna and skipjack on light tackle all day long.  On the way back to the marina, we saw boiling of bait with a hundred of birds flying on the water surface.  We were in confident that something big got to be under the water.  Set lures again and trolled for 20 min.  There was a big splash and a jumping marlin behind the boat.  A 100 kg (222 lb) marlin was landed in the end.
