My dealer told me Bennington has at least temporarily suspended production of SV models, at least until they get caught up on all orders. Makes sense as the margin is much higher on all other models. So glad I got mine when I did!
Mine has keels on the bottom of the toons that are half round and solid aluminum, they are not a V like you have. I would not think yours have the ability to support the weight of the boat on a flat bunk.
What is it about the foam that is delayed? Is there a certain chemical required to manufacture it that is in short supply? Petroleum by-product or something?
Nevermind, kinda answered my own question with THIS ARTICLE
