I have a 99 mastercraft sportstar. I'm looking at the Monster MTK tower. Would I need to add additional bracing? I'm not sure how thick the fiberglass is.

Hello, For the MTK Tower we recommend having a minimum of 17 inches of unobstructed fiberglass to mount the tower. If you have more than that, even better. We recommend using starboard, marine grade plywood, or sheet metal as reinforcement under the fiberglass.
