Mass. Gen. Laws ch. 131 § 69
A person shall not carry or use a bow and arrow while hunting unless said bow and arrow meet such requirements as may be set by rules and regulations which the director is hereby authorized to promulgate. Such rules and regulations shall prescribe general design, weight of pull, and type of bows and arrows, and shall conform to standards generally accepted for bows and arrows used for hunting purposes. Nothing in this paragraph shall permit the use of crossbows by any person other than a person who is permanently disabled such that the person cannot operate a conventional bow and arrow, as certified by a licensed physician. Any costs associated with obtaining the medical documentation, re-evaluation of the information or a second medical opinion are the responsibility of the applicant claiming a permanent disability. The issuance of a crossbow permit under this section shall be subject to rules and regulations promulgated by the director.
