I may have a solution for you. I am selling my 1983 (launched 1984) J/30 'Waltzing Matilda' - hull #456. She is currently stored in Mattapoisett, MA at the northwest corner of Buzzards Bay.
She is being sold 'fully found' and is a sound and dependable boat that I have sailed and occasionally raced for 31 years (she has done very well in distance/overnight races vs. some of the best PHRF sailors in Buzzards Bay - and I have the silver and crystal to show for it).
She is ready to be launched or trailered to her new home. I just finished prepping and painting her bottom and she is ready to go. I commissioned her Yanmar 2GM engine this weekend - and it started immediately with the first crank.
Her sails are in great shape for cruising and there are no problem areas with moisture or other concerns. While she's not a new boat - she has been well cared for and I think you will agree she is well-equipped and a good choice for the kind of sailing you are planning.
It is now time for me (age 75) to downsize to a smaller boat - that doesn't require someone besides my wife to get out on the water. I am readying a complete list of her gear and also many photos that I am getting ready to post on the J/30 Class
website (as soon as I figure out how to do that).
If you are interested, send me you e-mail address and I will pass these along to you within a couple of days.
