congratulations! I have been a General for 30 years (not have the fire like Roger to upgrade--I should! Worked a lot of MM thru the years as we were cruising and it is a great medium to keep in touch with other boaters, phone patches and to make new friends as you travel. We use 2 meters when on the ICW and local waterways (even the PNW) and all sorts of good things from dockage, to a ride to the grocery store to great fish recipies!
2 M or 440 is easy on the C Dory. HF is a bit more difficilt--but I like two hamsticks to form a dipole. No ground necessary, and you can run up to 600 watts if you wish. (Charlie got all of my gear with Thatway--but Thisway will have 2 meter aboard for this summer's cruise!
The Northwest Boaters net is very good--3,865 MHz at 08:30 Pacific Time. Also a number of 2 meter nets in BC which are very active.
Have fun!
