I have to diagree with those numbers somewhat.

With Doctor:

A Doctor has a Medical Degree and 5 ranks in t/Med. The degree part, looking at the character creation worksheet, means that as a graduate he will have a minimum EDU of 14, for +2. Total skill minimum of +7. Against DC 10 that is a failure on a 1 or 2 only, so 1 in 10.

The DC for the Fort save is 6, but you get +1 per rank fo the attending medic (T20Lite pg50), so the DC is 1. As a 1 is always a failure then that is a 1 in 20 chance of failure.

1 in 10 followed by 1 in 20 works out as 1 in 200 (0.5%) passengers dead when the doctor present is straight out of med school. If he has a total of +9 nobody *ever* dies, as the roll of a 1 on a skill check is not an automatic failure (PHB pg 60).

This alters a bit if there is a lesser trained person on board, with the worst case of T/Med 1 and EDU 10 being 9 in 20 and 1 in 5, giving a 9 in 100, or 9%, fatality rate (assuming no Fort save bonus on behalf of the passenger).

Without Doctor:

The fatality rate without a trained medical supervisor present based on DC6 would be 25%, if nobody has a Fort save bonus. Even a +1 to +3 cuts that down a lot.

So looking at this, only travel on a ship with a licensed Doctor. Any passanger liner worth its salt will have a good doctor on board, so won't loose anyone most of the time. The smaller ships, strapped for cash to pay highly skilled doctors, may loose a few people in a decade.
