In the GURPS Traveller: Starports book there is a design for a 100 dton first response and rescue ship based on a Type S Scout hull.  I really liked it – so here is my High Guard Version.

It has no jump drive so is limited to in-system operations. It has a powerful 3G maneuver drive and sufficient fuel for 28 days continuous operation.  The drive room has been repositioned to what would be the upper gallery on a Scout/Courier.  It has cramped seating for 35 evacuees, 12 emergency low berths and six  Auto-Doc medical beds. Three Grav Ambulances are housed in a garage where their rear door can be sealed with the ship to create an airlock between vehicle and space ship.  There is a large triage area and a lift that can take patients to the medical ward below.

Crew is variable but usually four, although in an emergency more medical staff can be carried.
