Jantzen Fuel Depot sits in the marina cove on Hayden Island, just east of the I-5 Bridge. Coming from the main channel, use the bridge as your landmark, then look for the forest-green floating building with yellow trim at the head of the covered-slip rows. The fuel dock fronts the water at the end of that row, nearest the channel, so you can reach it without entering the covered slips.
