That Acura MDX, approximately an '05, has a tow rating of 4500. That boat, which is NOT as big as so many of you are saying, looks like a Four Winns F244, it's not a "deck boat" its a bowlder sport boat and total, trailer and all, its around 6000 pounds.
This guy is a bit over but if he knows how to drive, he is gonna make it to the boat ramp, The car is all wheel drive and it will haul the boat out on a slippery ramp.
Personally I wouldn't do it, I'd use a truck to tow it, but it's not as bad as some of you are making it sound.
And someone mentioned weight-distributing hitch - boat trailers have surge brakes, not electric. Weight distributing hitches really don't work well with those.
