No firsthand personal experience, but I'd suggest checking out some of the more popular cruising video blogs in You Tube channels to get an idea of what the finished product might look like.
Newer models of GoPro are the stock in trade, with various flexible mounting devices on the boat, plus various hand-held sticks or 'worn' rigs (helmet cam, dinghy cam, etc).
... it all depends who your intended 'audience' is - friends and family? general You Tube audience? targeted audience (like one of the family/couple/solo You Tube sailing channels)
For high-end, artistic production, I'd suggest a You Tube channel called 'Sailing Uma'
A more basic version might be: Sailing Nandji
- both use multiple cameras (incl their phones) and drones
- they do good on-land and under water videos too
For a fun, light-hearted family example that looks like it's mainly for friends and family back home and not for 'click bait' on You Tube, try: Cruising Kiwis
For fairly basic production, but from a much more personal level of interaction with audience (mostly phone and GoPro, and a very little by drone (until it ditched in the sea)): Untie the Lines
For largely informational cruising videos (knowledgable, but very dry): Patrick Childress Sailing - SV Brick House
A pair of solo sailors doing it all at once:
For a very basic one-camera example (plus occasional phone shots), try: How to Sail Oceans
For a similar basic 'production' level, but done mostly in very challenging conditions: No Bullshit Just Sailing (NBJS)
- these two also use drones, but sparingly
There are lots and lots of other you tube sailing channels spanning the above 'production value' range from basic to virtually professional. Unfortunately (IMHO), many sailing channels are tarting up their weekly productions expressly to solicit Panteon donations (some more subtly than others) so they can fund their lifestyle. (e.g., Sailing Delos is among the worst in this respect)
Good luck - I'm sure it'll be fun and rewarding capturing your adventures!
