Looking for boat to share expenses for big island Hawai

I'm trying to get a fishing buddy for Kona side. My old friend died and his wife gave the boat away to her son. We always would meet at gas station where I used my card for gas and ice. Shared fish. 1 for boat 1 for him 1 for me. I think it's a fair trade. His gear and boat. Don't want another boat because we might be moving after 20 years here on Kona side
