Back in the day ... (I used to own TWO 2000 CP25's, at the same time!)
I had one trailer, two boats.
now just one boat, no trailer, but I have a CP23 trailer at my disposal if I need it.
They used to use Performance Trailers, but they're gone, kaput, sunk in 2008.
I'd call Rich or Gerry and ask what they could dig up spec wise.
I know it was galvanized steel. Dual axle. w/ drum brakes.
Knowing what I know now, I'd spring for disc brakes, torsion axles.
Keep the adjustable bunks; she'll actually stand on her keel and you can drop bunks intermittently for bottom work, if necessary.
