I dont know….45 is plenty fast to cause a fatality in a car so its certainly enough in a boat. I recall a simulator for a car wreck. I believe even at 15mph your arms are not strong enough to prevent you from hitting the windshield in a head-on collision. If you look at the pics, it looks like the console of the BCB was pretty much destroyed. A person sitting in that spot would have no protection to speak of.Jim EbarbMany, LA (Toledo Bend Lake)2004 Cougar/ 225 OptimaxHumminbird Helix 12 Chirp SI on BalzOut Mount at bowLowrance HDS 7 at bowHumminbird Helix 12 Mega SI on Ram Mount at ConsoleLowrance HDS 8 in dash at console
