Practically every travel office and guesthouse in Ayutthaya sells boat tours around the island.
These typically cost 200 baht per person, take place late afternoon and make stops at Wat Putthaisawan, Wat Chaiwatthanaram and Wat Phanan Choeng. The boats are typically large and noisy, and you'll most likely be sharing them with other travellers, but this is not a bad option if you want to see these outlying sights (and you should as they're some of Ayutthaya's best) without making the effort to cross the river and reach them on your own.
Boat tours can also be arranged independently by heading down to the pier at the northeast corner off island near the police station and immigration, and negotiating a boat driver to take you to the destinations of your choice.
Expect to pay around 500 baht for two hours if booking a boat on your own.
