Clarence -
My board is an aircraft carrier. I have tried to get it to go over but have not been able to do so. I routinely carry three rods (1 spinning, 2 fly), a cooler with water and snacks, a pack full of tackle, a paddle, a knife, an anchor, my life jacket and a dry bag with a phone and truck keys.
Look towards the fishing specific SUPs. I have used the general purpose all around boards, but a jack of all trades is a master of none.
I've had buddies use boats, canoes and jetskis to go fishing from, but I like the peace and quiet when I go fishing and when you are having fun, you're not exercising (even though you are) - I'll take the SUP for most fishing applications.
