Sultra you are looking for a mod not a trainer. Trainers for the most part manipulate the code in memory affecting some sort of changing quantity. Mods affect alot more. The tensile strength of the hook would be a mod as the strength does not change in memory. It's limit is either reached or not.
As I am not a coder I could be wrong. This is based off of many decades of trainer and mod useage.
if you are getting 'trainer cannot find game' message at F1, then you have old version of trainer. please delete your trainer, clear your internet cache, and redownload the latest trainer. it looks for all versions of the game and attaches to it.
if you still get message then you have some wierd named version of the game-
