Let's say that I have a boat from island A, after a few turns I move boat to island B, now can I start a settlement on island B? Or do I have to make a full shipping line from Island A to Island B or can I just move one ship to island B and start a settlement?

I have read the Seafarers rules booklet, but I have not been able to find any information on this.

Boats are like roads with a few exceptions:

  • they must border at least on one side to water.
  • they require wood and sheep to build.
  • you can pivot the last ship in a row of ships (but it needs to stay connected).
  • they are affected by pirates

You can only change from road to ship (or ship to road) through a settlement (or city).

In order to build a settlement on an Island where you have no settlement yet, you need to build a row of ships starting from a settlement at the first island until you get to the second island. You can now continue building ships along the coast, or you can build a settlement. And if you are the first to build on an island, some scenario's reward you with an extra victorypoint.

    Ok, sorry I misunderstood the ship "movement" rules, I thought you could just move your ship around anywhere you wanted. Thanks for the clarification @Toon Krijthe

You need to create a full shipping line. If you want to move a ship, you have to place it so that it is attached to another ship, or to a city or settlement.

You can never reach another island with just one ship.

    You can reach an island with one ship, if there is only one sea tile between two islands. You can't build a settlement because of the distance rule ;-) Commented Apr 14, 2016 at 12:14

The manual doesn't clearly state if a shipping route needs to be connected to a city, so

If your shipping route reaches a coastline, you can then build a new settlement on that coast, even if it's a new island.

is everything I can find on that topic.
