Anybody know about Alaskan "Lite" boats?

[49erjimmy]

I need to carry a boat on my truck canopy because I pull a travel trailer and I wanted to use a Smokercraft Alaskan style boat because of the high sides. I got on the smokercraft website and can only find data on their new models whcih are shown to weigh 185 pounds. This is a little heavier than I wanted to load on the canopy but I have heard that there is a "Lite" version that still has the high sides and is identical to the standard Alaskan but may be a little lighter. Problem is nobody seems to know. I called several marinas and talked to employees but they didn't know the answer. Does anybody know if the Lite model of the Alaskan weighs less than the standard Alaskan and how much? Thanks, Jim
