The Uk currently has 2 River II and 3 River I Patrol boats run by the RN (there is also 1 River class in the Falklands) - these all have 30-40 crew and can land a helicopter
they also have Border Force vessels - 4 x Stan 4207 &1 x Telkka Patrol vessels (12 crew) plus 8 x Delta ARRC 190 small rescue craft (6 crew)
I guess they also deploy mine hunters etc if necessary
