I assume you're aware that some parts
of the PI are fairly hazardous regions, right? And from where you are now, the routes for getting a sailing vessel there are likely even more so for some parts
of the route
. Think pirates.
As to officialom, you might try the US State Department, & other government
agencies which deal with travel. Plus of course, contact the appropriate folks in the PI directly. Though be aware that what you're told, & what you encounter in real life when you get there, can differ vastly.
Also, get in touch with several yacht delivery
companies. Being sure to vet any which you're seriously interested in. But they'll have info on delivery
costs, as well as officialdom, if it's a region to which they commonly deliver boats, or hire out captains & crew to work
in. Ditto on sailing routes, safety
Can't help you much specificially on the deck
cargo bit. Though most likely Bing, & Google
could. At least to start. And FWIW in the last Volvo
(VOR), there were some regions where the organizers had the boats shipped as cargo, rather than have the crews sail through them, as they're just too dangerous to sail though on a high value target like a fancy yacht. And it's easy enough to check where specifically those boats got shipped to & from, as well as what the plans for the current
VOR which is about to start.
