I caught many 10 to 50 lb tunas trawling, at 4 to 7 knots a 5 to 10" "Malboro" RAPALA.
We call it Malboro as it is a red headed and white body lure.
The brand is RAPALA : A rigid plastic lure with a stainless steel
lip which vibrates and shines in the water
, even under moon light.
I caught Tunas in the western and southern Med, only in deep waters.
e.g; 20 miles south of St Tropez, 20 miles west of Corsica
, between the Balearic islands and Marseille, around the Stromboly, East of Syracuse., South and west of Malta
, South of Santorin...
but I never caught anything in the ionian
, or Aegean sees.
Nor in shalow waters e.g. not in the less tha 100m deep straight between Sicily
My trawling gear consists of 3 meters of bungee, a small bell , 10 meters of easily seen and handled 4 to 6 mm rope
+ 300 lb ball swivel + 10 meters of 200 lb nylon + 30 cm of 100lb steel
No rod, no reel, no lengthy & fragile 50lb line .Tuna hoisted aboard by hand without needing to slow down ( except for the bigger ones).
