Last fall I purchased a '16 Craz. This is my 1st boat and recently moved to the lake. The lift is a 9k lb hi-tide 4 post lift, but with two flat carpeted boards as the previous owner had a pontoon. We're taking delivery of our boat in the next cpl weeks. I can buy the attachments from hi-tide to flip the boards up. But, 1) do I need more clearance than 8" -- current boards are 2x8x12'? Also, how many inches is best between the two boards? I've called dock folks, but they're backed up and seem to be charging waayyy to much. Thanks!
