This is a big grey area with multiple answers depending on exactly what you mean.
For example... my trailer gets used twice a season in salt water - and it travels about 5 miles each way in very rural areas with little traffic. That's horrible for the braking system as everything freezes up during non use and then grounds the trailer.
I took the brakes off and exchanged the braking coupler for a non-braking unit. Now I have no worries of getting stranded, other than from an actual breakage or bearings, of course.
As long as the carrying capacity of the trailer is at least close to your boat weight - for short trips like I'm talking about - you'll be fine.
The same goes for the tow vehicle - as long as you're not grossly underrated, you'll be fine
