Welcome Hookedandcooked!! Unless that Johnson is mighty thirsty you should be fine on the gas consumption going out to the Chesapeake Light Tower (only 16 miles). Been out there a few times myself on my buddys 19ft. GW and didnt have any trouble. I haven't taken my V out there yet but May is coming and the Big Spadefish usually school up at the tower then!! Hope ta get out there soon. Just as the others said keep a close watch on the weather and all your safety equiptment up and running and you'll be fine. Good Luck and let me know when the Spadefish come in, the're alot of fun and mighty good eatin!!
