Monorail is typically faster however depending on the crowds and if you are close to the dock, a leisurely boat ride early in the morning might be just the right way to go, dropping you off directly in front of the entrance.

In the battle of Disney transportation, the monorail is technically faster than the ferryboat, but only if you consider the actual transit time on the tracks versus the water. The "Express" monorail takes about 4 to 7 minutes to complete its loop around the Seven Seas Lagoon, whereas the ferryboat takes approximately 10 to 12 minutes to cross. However, the true "speed" depends heavily on the crowds at the Ticket and Transportation Center (TTC). The ferryboats are massive, holding up to 600 passengers at a time, which means they can often "swallow" a large queue in one go. If you see a massive line for the monorail, the ferry may actually get you to the park entrance sooner. For the absolute fastest results, many "pro" travelers check the Resort Monorail line; while it makes stops at the Polynesian and Grand Floridian, it often has significantly shorter wait times than the Express line, potentially putting you at the front gates faster during the morning rush.
