You can launch from County ramp
at north end of Fernandina Beach, then pay for a month storage at Tiger Point marina or Olde Town marina, both just a short walk south of the ramp.
Or Clapboard Creek Fish
Camp in Jax where you can launch and park at the same spot.
Or use Lighthouse Park ramp in St Augustine and park at nearby Anastasia Storage
But there are miles and miles of No Wake zones south of Jax all the way to Daytona. If you like to run fast, better trailer further south!
