Under 30' you can get away with a single
Over 30' you will want twins
MSRP on a Verado 300 is around $24K plus rigging.
MSRP on a 27 Concept single 300 Verado is around $50K, decked out around $65K.
My 2007 Concept 32'6" w/twin 300XS decked out was around $190K MSRP on trailer.
34' Nor-Tech w/twin 300 Verado base retail price is $303K. Paint, trailer and options extra.
39' Nor-Tech w/trip 300 Verado Base retail price $395K. Paint, trailer and options extra.
The Nor-Tech is a different boat than the Concept. Not in a bad way, just a total different style of boating. All in what one is looking for.
Of course all of those numbers are MSRP so take it with a grain of salt but have to start some where.
New 36' Concept with trip 300 Verados decked out can be had for around $150K in the real world.
