Rig before the dock line comes off
Everything that can be rigged at the dock should be rigged at the dock. Camera build, head calibration, RF check, media formatting — all of it is faster and safer tied up than underway. The Basilisk's crew treats departure as the start of shooting, not the start of setup.
Manage talent like the deck is moving — because it is
Wardrobe, makeup and hair need a shaded, stable place to work; on the Basilisk that is the air-conditioned cabin, not an open deck. Schedule talent's time on the exposed deck in short blocks, and keep the horizon in their eyeline between takes — it is the single most effective seasickness prevention there is.
Battery and media discipline is the day's real schedule
On water there is no runner to the rental house. Double the batteries and media you think you need, and offload to the DIT station on a rolling schedule, not at lunch. The Basilisk's blackout DIT suite means backups and a first-look grade happen while the next setup is being framed.
Protect the golden-hour window ruthlessly
The best light on water is short and it does not wait. Put the hero shots in that window, have the vessel in position twenty minutes early, and let coverage and B-roll happen in the flatter light around it. The captain can hold station on a mark; what nobody can do is move sunset.
