Often, the best resource for questions like this are forums and travel sites that allow enquiries that are then responded to by members of the site.
For instance, the Living in Cebu forum had a thread opened just over two weeks ago (I am editing this post on May 31st) titled Toledo-Boracay Planning a motorbike trip, advice needed. There might be similar posts — I found a couple from 2007, and another from 2006, but decided not to link to them for concern they are now stale.
Lonely Planet‘s Thorn Tree travel forum had this from June 18 of last year: Getting to Boracay from Cebu.
The site Boracay Board has this page: From Cebu to Boracay – Philippines.
And the question How can I go to the boracay from cebu by ferry? was asked just this past April 23rd at HugePocket.com.
You will surely find other discussions.
