Sport,
If I was you, I would get off of this puter and take a run down to Lynn for a dry run and find the boat. Basically, you down down 95 to route 1 towards Beantown and get off at Route 129 where the Lynnfield Tunnel is.
Follow 129 East towards Lynn and continue down Lynnfield Street.
Traveling South Using Route 1 Take Exit For Route 129 East You Will Enter A Circle / Rotary Follow (Route 129 East) Lynnfield Street For Three (3) Miles Turn Right Onto Boston Street After 3/4’s Of A Mile You Will Come To A Traffic Light, Turn Left Onto Washington Street After One (1) Mile Turn Right On Broad Street (Route 1A South) Within 1/2 Mile You Will Want To Take A Left At Traffic Light Onto Marine Boulevard Remember, we have your money, so don't be late, we will leave without you
Once again, I recommend a good dry run to make sure you know where it is Dave
