I just went through a search for a non flybridge trawler
and bought one. My reasons were exactly the same as yours.
There are two types of boats that qualify (IMO) as trawlers which don't have flybridges: tugs and downeast. Yachtworld has a specific search designation for both of these.
Most, maybe almost all of these boats are fast trawlers. They cruise
in the 12-15 kt range generally and not at displacement
speeds. Most have engines in the 200-300 hp range. Only one boat that I found was built for displacement
speeds- a Cape Dory
28 with a 100 hp Westerbeke
You will find Nordic
Tug 32s from the low 100s. Downeasters are all over the place. A brand new MJM 28 is more than $300K. Ended up buying
a 25 year old Cape Dory
28 with a good gas engine
for low $30s.
FWIW it is hard to find a downeaster with a long cabin
and a galley
down configuration. Some custom boats are built that way but I could find nothing in the low $100s. So I bought the old gasser for a great price
and will probably repower
