There will be times when it it necessary to determine whether the adventurers are able to keep control of their vessel and the Boat Handling test is used for this. Characters with Row or Sailing skills (as appropriate to the type of boat in question) make a Boat Handling test based on the average of the Int and I scores. Characters who do not have the relevant skill make a Boat Handling test based on half this value. On a sailing boat, the Boat Handling test is made by the character who is manning the tiller; on a rowing boat, it is made by the oarsman with the highest test value.
