There's also more information and varieties on boats in the Arms and Equipment Guide, if you have that. The PHB will probably serve most of your needs, though.
I'm hoping that the upcoming Stormwrack will have some more detailed boating information.
IMC recently the PCs took a boat trip down river. Speed etc. -- no problems. All covered. But if some unpleasant situation came up -- like an attack by a giant eel, for instance -- and the PCs had to do something to control the boats ... well, I was hard-pressed to work out what skill would be appropriate.
I winged it, and it was no big drama or anything, but I was peeved that I couldn't find some sort of rules on "how to control a moving vehicle" in the DMG or anywhere else for that matter ....
Nah, it'll probably be a rather boring afair, with you strapped to a table in an orange jumpsuit mumbling, "Scarecrow... Scarecrow..." over and over again...
