In the course of its 50-year history Revell has released some of the best ship model kits in the world, and some of the worst. Even more than most companies, this one has ridden a real roller coaster in terms of merchandise quality.
Both the kits in Yann Solo's next-to-last post are quite old, but that isn't necessarily a criticism. The trawler originated in 1971. (My source on all this is Dr. Thomas Graham's wonderful book, Remembering Revell Model Kits.) It originated with the now-defunct Revell of Great Britain; it first appeared in the U.S. in a box labeled "Russian Spy Fishing Trawler Volga." I don't remember it very clearly, but I think it's generally regarded as a respectable if unremarkable kit - reasonably well-detailed, a reasonably accurate representation of a typical fishing trawler from the mid-twentieth century.
The tugboat is one of my all-time favorites. It was one of Revell's first ship models, with an original release date of 1956. It's a scale model of the American west coast harbor tug Long Beach, which is the name the kit had for many years. It's been reissued many times under different names. (Sometimes Revell Germany has tried to promote it as a generic European tug, but any tugboat enthusiast can identify its distinctively American shape in a second.) Even by modern standards it's a mighty nice kit - a wonderful, characteristic tugboat shape, lots of detail, and three superb crew figures. (I've bought several over the years just to get my hands on those figures, who've wound up on sailing ship models.)
I've got the current version in front of me at the moment. I have three small reservations about it. One - as one would expect in a 40-year-old kit, there's quite a bit of flash to clean up. Two - it's molded in bright red plastic. Most tugs have black hulls and large areas of white or light grey on their superstructures; this one's going to call for several coats - preferably with an airbrush. Three - there are two ugly, inexplicable plastic lugs sticking out from each side of the superstructure, next to the main deck. Their original purpose was to anchor a pair of metal screws, which held the superstructure to the deck in the version of the kit that contained an electric motor. (The superstructure had to come off for battery changes.) Slice off those four blobs, trim the flash, give her a good, careful paint job, and you'll have a first-rate model.
Hope that helps a little. Good luck.
