1964 Bertram 31 Softtop Express

Higganum, Connecticut


Dalmatian was purchased by current owner in early 2016.  Having already had an extensive refit in 1998 including new engines, Awlcraft paint, new vinyl top etc., we have nearly completed an almost three year update/refit.  The Yanmar 4LH-STE 230hp diesels are very economical and in excellent condition, having been yard maintained.  The boat shows as nearly new, and in true Bertram 31 form, is extremely sea worthy and built to very high standards.
