What type and how many tie downs do you guys recommend to secure a boat for trailering? Boat is 16' long, and with motor weighs about 1300lbs. I was advised by the guy at the dealership that a single gunwale strap would be sufficient. Gut tells me I need more. Should I go with two gunwale straps, or combine one with some transom and bow tie downs? Something like this?: http://www.cabelas.com/cabelas/en/t...parentType=index&indexId=cat420011&hasJS=true I understand more is better, but I don't want to overkill either because that costs unnecessary $$$. One more thing, should I get a transom saver bar? The motor weighs 237lbs. Thanks for the help!
