Sorry I missed you, was cleaning out the bilges today. Getting ready to touch up some motor paint.I went north Very early today, Portland - Kennebunk then Rose's in Gloucester so my friend & I had lunch @ the Causeway across the street from your marina.
After lunch took a walk around your marina, saw your boat and that you had the engine box up like you went doing some work so went down to your dock .
Hung around a while and was going to say hi as the people on another boat on your dock said you had been around.
Really nice boat you have there !
