Piers, ferries, island buffers, and weather realism

Thailand ferries need pier identity, route fragility, and booking risk separated.

Thailand ferry intelligence only works when piers, routes, weather sensitivity, last-boat risk, and commercial booking layers stay separate. Use Marine Department and pier-reference layers for public water-transport context, OSM for pier and ferry-terminal geometry, and commercial ferry surfaces only when you need live schedules, seats, fares, and operator-specific booking rules.

Authority order

Use this order when a ferry route looks possible but transfer burden or weather fragility could still break the plan.

Authority order
RankSource layer
1.Source layer: Pier identity and mainland or island geography come first: know where the boat actually leaves from and what transfer burden sits behind it.
2.Source layer: Marine Department and public transport context explain whether the route is a public-water-transport issue, a pier issue, or a safety issue.
3.Source layer: OSM and map layers help with pier geometry, nearby roads, and transfer logic.
4.Source layer: Commercial operator and aggregator layers are for live schedules, seats, fares, and cancellation terms only when authorized.

Matching rules

Ferry pages work best when pier identity, route logic, and booking logic stay separate.

Matching rules
RuleMeaning
1.Meaning: Same pier name does not prove the same terminal, especially when island and mainland names repeat.
2.Meaning: Weather and last-boat risk belong to the route layer, not just the operator layer.
3.Meaning: A ferry route existing in a booking page does not prove same-day conditions are good.
4.Meaning: Pier geometry and route booking should stay separate so transfer burden remains visible.

Ferry-decision layers

Use ferry pages to answer the practical question first: what can break the move, and what should stay flexible until later.

Public ferry pages

These pages turn pier and route context into practical island-transfer guidance for the Andaman, Gulf, Trat-side islands, and deeper routes like Koh Lipe.
