Can a 2025 Chevrolet Silverado 1500 tow a Grady-White Fisherman 236?
It depends on the engine
We estimate a loaded Grady-White Fisherman 236 on its trailer at about 7,640 lb. 3 of 8 Silverado 1500 engine/package options pass with a 20% margin (for example the 5.3L V8 + Max Trailering Package). 5 are borderline (caution). Payload still needs checking against your door-jamb sticker: tongue weight plus two adults is about 1,064-1,446 lb.
Check your exact setup (add your door-sticker payload and real trailer weight)

"Published rating" is the lowest–highest conventional (ball-hitch) rating Chevrolet prints for that engine/package across cab, bed, drive and axle choices. PASS means the loaded trailer is at or under 80% of the lowest rating. Chevrolet: tongue weight should be 10-15% of loaded trailer weight and must not exceed rear axle rating, GVWR or max tongue load.
Tongue weight vs payload
Tongue weight should be 10–15% of the loaded trailer: about 764–1,146 lb. That comes out of your truck's payload along with everyone in the cab, so with two adults (300 lb) you need roughly 1,064–1,446 lb of payload before any cargo in the bed.

Confirm with your door-jamb sticker and owner's manual. Your exact truck's rating depends on cab, bed, drive, axle ratio, options and tires, and your boat's real weight depends on its engine, options, fuel and gear. When in doubt, weigh the rig at a CAT scale.
Gear you may need
Placeholder links (not affiliate links yet). Disclosure.
Trailer brake controller
Boat trailers over about 3,000 lb usually need working trailer brakes (check your state's law); an electric-over-hydraulic or electric setup needs a controller in the truck.
Class IV receiver hitch & ball mount
Match the ball mount drop to your trailer so the boat rides level; the hitch rating must cover the full loaded trailer.
Tongue weight scale
The only way to know your real tongue weight (10-15% of the loaded trailer) before it eats your payload.
