Where you are from will make a big diff on what you can get for aluminum boats. West Coast guys have some incredible boats that we can't get on the east side of the world.
I have a 1998 Lowe 16 ft V hull - V nose and flat bottom, high sides - NOT the chickenbreast john boat version. With 25 hp. It's been from ME to Key West and many points in between - ugly drab green Parker DB paint. Will run 1100# of people + 10-15 dozen decoys and get you there and back. Does bang a bit on the waves due to light weight. We've always run V hull boats cause dad never liked the low sides on a john boat. Bought it new and still using it. Tilt the motor up and float in 6-8 inches with 2 guys in there fishing or get out and push/pull it - will draw less.
I've run some mudflats with it - motor on edge of drop and side of boat on mud, buzzing along at full throttle - fun stuff. We've had a lot of fun in that boat. Use it for ducks, near shore, intracoastal, and backwater type fishing.
Recently decided to get a LUND SSV 18 with 60 hp. Yes, still a light hull and will slap if not careful but the 18 will run better offshore than a 16 due to bridging the gap on waves. Did tiller and am planning to convert to side console in a few years or sooner.
The Lund Alaskans are heavy boats, need larger motors, and won't slap nearly as much. Nice boats.
Anyway - if you are wanting to float skinny, have sides and protection from eating a wave in 2 ft chop, then a 16 V hull with a 25 would be a cost effective answer to your need. 16 is better than 14...
A used one would be even better. I recently saw a 16 Alumacraft V hull with 25 Yamaha 4 stroke, 2013 or 2016, BMT for $4500 - that's a rig that'll last a long time, use little gas, and give great service - though long about it but decided to run with the Lund.
