We are in our third game and this has been a constant debate. If you are exploring with two ships and the lead ship takes sufficient damage to sink, is it a successful explore? Some of us say it is since the second ship is there, and others say no since the lead ship sinks. Thanks in advance for clarification
The rules are very explicit. If you sink, you fail. It doesn't matter if you had a second ship.
If you did not roll a single success, or if your ship sank as a result of taking damage, the endeavor is a failure and your turn ends immediately. Otherwise, you succeed (even if you took damage).
