I trailer my boat a few miles at most to P4. There’s no way I’m taking some of the things mentioned above (jumper cables, rubber boots, full tool set, sockets, extra coat, extra bearings, hatchet, small stove). If I were making lengthy trips or staying nights on end, my list would obviously be more inclusive.
My list for the average trip (those in bold are the only things that come out and need to be loaded):
-water
-beer
-tackle and fishing gear
-a small quart of extra oil
-1 anchor that works well
-pliers
-measuring sticker (stays on inside lid of livewell)
-towels
-spare old prop and 2 tools to change it
-throwable and x2 life jackets
-battery charger for cell phone
-marine band radio
I’d be curious as to how many people above are well over the weight capacity of their rig with a maxxed HP motor, full tank of gas, and the lengthy lists of stuff when they bring a guest or two. I pride myself on being able to back up to the garage, unhook the onboard charger, and be launched and idling up river in ~10 minutes flat. If I had to take longer or packed half the gear some have listed, I wouldn’t get out the 4 days a week that I do during the summer.
