I killed one or 2 ships with it I dont remember
Considering the Quad Hwatcha galleon is relatively effective, I wouldn't consider "1 or 2" kills to be a success with it.
Also I remember playing a game exactly as you are describing with 2 galleons on the enemy team on labyrinth, I forget who I was playing with (sorry to whoever I forgot) but I remember my team mate having a blender fish and I having a gat/mortar pyra. Needless to say it was a slaughter and I believe I got atleast 4 kills on my own and at the most 1 death, but perhaps none
I think the match shows that a blender fish is a Galleon's worst nightmare as the other team's galleons spent 1/2 of their game trapped on the floor and the other half moving from spawn. Also contrary to most opinions, my gat/mortar pyra did excellent work on killing the trapped galleons quickly with the standard damage of a meta set up and the mobility of a buffed balloon
