Your absolutely correct in your assumption and yes you will be able to haggle a better deal just after the show especially if you go for one of the lower more budget rib manufacturers, earlier this year i seriously looked at XRibs (now XS) and they were doing deals based on show prices after LBS, i didnt like the fact i couldn't view the boat i was interested in as they didn't yet have one made up, and they didn't have one i could demo on the water either , suppose it was a bit like asking me to buy a car i'd never seen and never driven and had only seen and read dsecriptions from a sales literature hand out !! and even when i started to back away they kept lowering the price and throwing in extra's. Now i know they were desperate for business earlier this year and to get a foot hold in the Rib market, and i suppose flooding may have been a good tactic, after buying a dog though i'm now more weary about how i look and rate boats especially relating to the times of year i go boating and what sea states i want to go out in !!
When i do though think about upgrading my current boat i might look at this particular manufacturer and ask questions again, they did seem like value for money especially as you go up the size range, hopefully by then others on the forum will have had some experience with theres and be able to give feedback.
