Adrian, I had a Warrior 195 (not made any more) with a 150hp outboard which we trailed. They were 19'10" and weighed over 1400lb without the engine, fuel batteries etc so came in at around 1900lb all up. 2 of us could launch and retrieve at baiter on a full multi roller trailer easily at high water but half way down the slip was very hard work, at low water forget even trying to retrieve here. Due to the steepish ramp at Cobbs I could launch there single handed but you obviously pay a premium for launching there.
The trophy boats are imo very good although the older ones "Bayliner" were near the budget end and so was the quality but they are still very useable. The newer "Trophy" boats are of good quality. The biggest thing to be careful of is the engine as this can give grief and should you make the wrong choice be very costly.
