We built the infamous challenger boat 3 years ago . being a 2400 with twin merc 150s at the time. i then had the chance to fish offshore in Eden up and down the coast for marlin later that year and i still rate them extremely solid offshore boats. they may be dated in some of the outfittings compared to US boats. but they are like your nannas couch. build solid.. a bit old fashioned but super comfy
i also crossed port phillip bay a fair few times in it , with the typical "from every direciton at once" PPB chop and slap. and i just sat the autopilot on and watched netflix the whole way across
Id be happy to talk you through some of the things we did to it. and our thoughts on any future versions
