Simms Bros.
Dorchester MA
William E. and Eric J. Simms started this fine yacht building yard on Freeport Street, in Dorchester, in 1933, on the site previously occupied by G. F. Lawson & Son. Unfortunately, it had to close in 1957 when the site was compulsorily acquired by the D.P.W. to make room for the Southeast Expressway.
