I agree. Hes a mess
I suggest you will simply want to have names of your witnesses as to what actually happened with the boat and also that you made an offer to return the tourney fee - which you did not have to.
Each of you assumed the same risk with the fee that you may make it to the fishing spot, that you may or may not catch a fish
Then you just need to see if he is going to sue you.
If he asks you again for the money - request he put it in writing as well as why he feels you are responsible.
Then you can answer in writing that you do not see how you are responsible for that loss since you all assumed the same risk.
I suggest you want to keep it all in writing now.
I think I have answered all your questions; however, if not, please let me know.
Remember, I can only answer and provide true and correct information for what you ask.
Otherwise, please rate this service below Good to Excellent so that I may get credit for my time and information. Thank You and good luck with everything
