This same principal carries over to charter captains, fishing guides, and first mates that provide services during your fishing experience. Typically customers will add 15% to 20% gratuity to the trip price, depending on quality of service. Although it is not mandatory, there is a certain etiquette for showing your appreciation. If you feel that the Captain or Guide was not deserving of appreciation, perhaps only a 5% tip is warranted; but we’ll get into what is good service in just a bit. Oftentimes, the gratuity you give goes straight to the First Mate (if applicable). In some cases, the tip is the only compensation a first mate receives, as they are mostly interns learning their trade. If you feel both the Captain and First Mate deserve gratuity, you can offer cash to both. The Captain may still give all or some of their portion to the First Mate, but the gesture is noted and appreciated. here
