Haha I got the "A" Part wrong I always do that. A is for January, B is for February, C is for March and so on...
When I do make it to the boat yard I'll do my best on measurements and pictures of the rudder.
I have not taken the sonic out that far. furthest in open sea I've taken her was from Bristol, RI to Block Island, RI I can never get the time off work to dedicate to a real trip. And in my personal opinion a 23' is a bit small for a coast trip unless you have a few expert sailers on board. But it's definitely possible. my uncle does FL to RI in a 26'.
Don't worry about returning the favor... Unless you have a extra forward deck hatch!!?!
