Helping Hands and Hooves will hold its 13th annual Christmas Day Swim to support the nonprofit's therapeutic horseback riding program for disabled adults.

Swimmers will take the plunge at Mattapoisett Town Beach at 11 a.m. Each swimmer is asked to give a donation of $15 (payable on the day of the swim), and the first 75 swimmers will receive a festive T-shirt.

All of the proceeds will go to Helping Hands and Hooves.
