Reasoning behind this has already been stated... It costs way to much money if you compare it to the money you get in return... Attendance has been very poor the past few years (it's about quality not quantity)... People going to this show want to see brand new boats, which Lavey hasn't built many, and they aren't going to bring older showroom boats, nor is it smart to build brand new showroom boats without them being sold...
Now just because Laveycraft isn't attending this show, it does not mean they are in trouble. The shop is full with boats being worked on weather it be service, repair, restoration, ect, ect... There is also a few boats on order that need to be built, stay tuned
Also, like mentioned Desert Storm is a much better venue to attend. With the combination of the street show and poker run, a high percentage of the people that will see you and your product are all boaters. Another example of quality over quantity, on top of that Desert Storm does produce a great amount of people.
So at this point in time, the strategy that Lavey is going to take is save the money and use it to continue providing for their customers aswell as using it for other venues that may greater benefit the company.
