I know the question goes, if you have to ask you shouldn't be buying but we are thinking of purchasing a 40-48 sport fishing boat, cabo, viking, hatteras, etc. We are going to partner up with another person and our boat purchase price would be around 600-750k so we would be buying used. Most likely wont happen for 2 years but want to start the research now. I am an avid tuna fishermen on our current Davis Boat (small only 25') Great fishing boat for our northern california waters but was thinking of getting a second boat/vacation boat for the lady and I to travel around and fish. This would be a boat we leave down in San Diego and fish down in Mexico and travel and around to see new spots and have a good time doing it. I was curious since you guys own these boat as to what your yearly expenses are and what the cost is to maintain operate, etc? My guestimate would be somewhere around $12K to dock, $3-4K bottom paint and constant scrubbing, $2-4k engine maintenance, clean and wax, $3k, insurance ??? As far as operating the boat, my guess would be somewhere around $200/hr for fuel consumption??? If you dont mind sharing i would love to hear your expenses and what a typical 2-3 day trip cost you to operate. Also any recommendations on boats for Southern California and Mexico fishing? 2-7 day trips. Able to sleep 4-6 people, have plenty of fishing room, etc? It sounds like from my readings that each year can be a total completely different boat.
