Rick,
I took the ferry from the west coast of PR back in Jul 2002.
Here's more recent and a lot more expensive info:
Mayag?ez--Dominican Republic Route
M/V Regal Voyager Ferry $109-$247 (tax included) per person, round trip
11-12 hours one-way
2- or 4-door cars $146.00
Vans & others $176.00
Mayag?ez to Dominican Republic
Monday, Wednesday & Friday
Departure: 8:00 p.m.
Arrival: 8:00 a.m. the next day
Dominican Republic to Mayag?ez
Sunday, Tuesday & Thursday
Departure: 8:00 a.m.
Arrival: 8:00 p.m. the next day
And from yahoo!
It is possible to arrive via ferry from Mayaguez, Puerto Rico, on Ferias del Caribe (tel 809/688-4400, Puerto Rico tel 787/832-4800), but it's a long, uncomfortable overnight trip. Ferries depart Mayaguez three times a week; the cost is US$144 one-way, plus the US$10 entry tax and US$60 for a private cabin. Plus the car of course.
