So Mark,I don't want this to sound weird, but, do you sound HAPPY on the VHF? Does it sound like your voice is smiling?
Does your VHF message say "We rented a car today to go around the island. Its expensive so I want you to come with me so its cheaper. No ratbags, only nice people should reply".
Or do you say: "Hi Folks is Don! Don from 3 Pirates! We're in X Bay and in 3 days we're renting a car and have 2 seats available. It will be exciting. We're going up Bahamas HIGHEST mountain! Visiting the 3 villages, Seeing the WHITEST sand beach and ending with Sunset at Point XXX which you can only get to by car. All this and it will only cost you $40! Guarantee you'll be back on your boat by Cruisers Midnight at 9pm. Call me IMMEDIAETLY after the Net. Remember its Don on 3 Pirates!!!!!!!!!!!!!!!!!!!!!".
