Both Mustang and SeanC have given good advice here.
I owned a 232 Gulfstream for 10 years and trailered it everywhere. Pros/Con's below:
Pros:
They are a roomy, safe platform with a "widebody" beam-to-length ratio. They are stable and really safe, given reasonable sea conditions and an experienced hand at the helm.
They have been built by Grady for many years and all the bugs have been worked out.
Grady has incredible customer service. Great front office. I have written many articles for Anchorline and Docklines and they are great to work with on all levels.
They just look cool. I realize this is a matter of personal taste.
The sightlines are excellent around the helm.
it is truly the Biggest 23 footer on the Market. It really is a great boat.
Cons:
Beam is 9' 3" amidships just aft of the helm area. This makes it illegal to trailer in most, if not all, states. Some get permits, some say screw it...Your call.
Speaking of trailering, if you plan on jerking it around, you will need a 3/4 or a full-ton truck. A gasser will do it, but you'll live Life under 10MPG. Diesel is the way here.
It will be 12' 2" to 12' 6" with a hardtop, maybe higher. Have a heightened sense of awareness regarding low hanging tree limbs, gas station awnings, etc.
DO NOT SKIMP on your trailer! Mine was 14K cap with twin 7K axles. I would do that again tomorrow if outfitting another trailer for it. The result of an under rated trailer or one close to cap is blown bearings, premature brake failures, and stress on components.
The Gulfstream has a cabin, but poorly designed, in my view. It has a beyond-useless stove & sink on the port side, which no one I know has EVER used. It takes up valuable sleeping & storage space. It has a "Top Bunk" that folds out, but only young children can sleep up there comfortably. You and your Wife can sleep in the lower area. It has a filler cushion designed for the purpose, and a head below the cushions on the starboard side. I never used mine. Sleeping that close to...well.... never appealed to me.
It is rock-solid, as mentioned, but it pounds in a head or quartering sea unless you really put lots of tab in it. This is due to the hull slap caused by the wide beam-to-length ratio. Safe as can be, but a bit bumpy in anything over a 2 ft wind-driven chop. It'll go up-and-down 4-6 ft swells all day.
Now, My Opinions, since I'm writing this:
The only viable power options are twins. Does it come with a single? Yes. Is it cheaper? Yes. Is it a good idea? NO.
Because of the weight and the extra beam and the fact that the engines are removed from the running surface being mounted on a bracket, it's hard to horse it around a dock in windy conditions or with a current running.
The twins are a game-changer with regard to close quarter maneuvering IF you know how to do it. If not, they will do you no more good than a single.
The Gulfstream needs twins for the reasons I outlined above. if you are not familiar with the nuances of prop thrust, inertia and the other factors that go into operating twin engines, pay a Captain to teach you if you buy a Gulfstream. You'll catch onto it by the end of the season with practice, and your gelcoat will thank you.
I personally prefer twin V6 200's for this hull. My cyber-friend Fishtales on here likes the 150's. Nowadays the Yamaha 200 i4's might be an option, although you'll lose torque and planing power without those 2 extra cylinders.
I would also encourage you to follow up on Mustang's advice by finding a good used model and save big. In case the boats not for you, you could potentially unload it for little or no loss if you keep it up during your ownership period. Let someone else eat that depreciation.
SeacC has good points as well. A Sea Trail is mandatory to make sure you bond with the rig and are comfortable with it. Also, be Real and make sure you'll really use it before sinking that kind of Jack into one. So many have sold them prematurely after purchasing with the best intentions.
These are good problems to have. Good luck!
