under 6000 pounds? with trailer and gear? that's gonna be hard to do in an ocean-able 23' boat that isn't aluminum.
ignoring that detail.....
23' walkaround with a large 4-stroke outboard on a bracket. This will give you maximum FLAT deckspace and will ride more like a 25' boat due to the extended position of the motor. The WA will allow easy access to the anchor and chasing fish. The bigger motor wont have to struggle with a full boat load of "stuff". Dont get a boat that has a minimal motor. It will have been "minimalized" everywhere else, too.
Cuddy cabin with a mini galley. porta-potty in a stand-up "closet". The closet offers privacy AND it gives you a place to store foul weather gear, life jackets, etc, etc, etc.
You aren't going to live in it so the only "space" requirement is for YOU to stretch out and catch a quality nap in the v-berth. Make sure you fit comfortably. (If you fit, starfish will fit, too)
Find a 1-2 year old boat with realtively low hours. The depreciation will already have taken place, and your electronics will be bought and installed. Electronics are only expensive if you are the one buying them new. QUALITY installation aint cheap.
Plan on another $5k CASH after you buy it...just 'because'. If you dont use it all, it will pay for fuel.
Better check on the loan situation/availability NOW. Find out what they will require from you and about the boat - especially on a used boat. A used boat will/SHOULD be professionally surveyed/appraised if you are going to be making payments on it. Thats $300-$500 thet you pay up front.
I'm not going to get involved into what brand. They ALL have pros and cons.
When you see something you like, go for a ride in the afternoon windy, bumpy conditions; NOT in the early morning glassy conditions. Minimum 20 minutes out of the harbor and 20 minutes back in. Pay for the fuel.
Good luck!
Maybe you can find a cat-type boat in a divorce sale.
