Royal Hammer is keeping the reggae faith every Sunday this month at Jones Landing (6 Welch St.) on Peaks Island. Sure, not a few people get royally hammered at this seasonal bacchanal, and the ferry ride back can be obnoxious, but the combination of hot sun, irie vibes and ice-cold beer is always hard to resist. Music at 1 p.m. (no cover before 11 a.m.). See cascobaylines.com for ferry schedule. 766-5652. joneslanding.net.
