This Sport Nautique has the original trailer, but it's different than my Ski Nautique. It has a winch (SN doesn't), bow support pads, and a bump stop set up, but no safety chain or devise to keep the boat from sliding back, which they can do when wet and on a launch ramp. Not trusting the winch to keep it on the trailer, I added a safety chain today. The po never used one apparently. I thought they were required?

I've seen a boat launch up-and-over its trailer as the result of a rear-end accident.
My Ski Nautique trailer sounds similar to yours: bow-stop, pads and a winch. So, I installed a grade 80 "crash chain" and D-ring on my trailer. It will take one helluva bump to separate the boat from the trailer. And, yes -- the crash chain saved my Nautique from sliding off the trailer when pulling out of the water on a steep ramp. My ski partner didn't properly lock the winch handle and the boat started to slide backwards. When the Nautique stopped sliding on the bunk boards, the prop and rudder were 6" off the concrete ramp. Glad I had the safety chain properly attached. JQ

The chain is a good measure, but equally important are transom ties. They, too can help keep boat on trailer.
If tailer has no tie down rings, a closed-end eyebolt works.

Yes, I use transom ties too, but after the boat is out of the water and on flat ground.

After an accident that was my fault after deer ran in front of me while I was towing I added two front chains, one to stop the boat from coming forward and one to keep it from moving rearward on the trailer. My boat almost ended up in the back of our BMW X5. Going down hill with a trailer with wet bunks the car in front of me stopped to avoid a few deer that ran in front of the car. I hit the brakes hard while going 45-50 mph trying to stop. Both rear straps broke, the boat came forward, bent the two upright stops on the trailer and ended up with the bow sitting on top of the bow stops. It was all fixed but now I use much stronger rear tie down straps and the two new front safety chains. My winch strap sits ahead of the boat so it was no help stopping the boat, it would have come into play if the boat went another foot or two forward. Front fiberglass damage and the prop was damaged. Could have been worse. I was almost stopped, under 10 mph when I hit the car in front. $13,000 damage to the BMW and $5500 to the Nautique, $1,500 to the trailer. I fixed the trailer damage. Yep, would have had zero boat damage with better tie downs in advance. The pictures are on this forum, it was about 5 years ago. When I was getting estimates for this repair I saw another boat that was much worse than mine, it had come up over the bow stops to about mid boat and the trailer was damaged much worse than mine.

Launching is the worst part of boating
Yep. Bow chain installed and winch I’m still nervous though Afraid to drill holes in transom I do use a fat tie down strap across rear |

I connect the rear tie downs to my swim deck supports.

Took my 78 swim platform off the 67 to do repair and paint but like the nice smooth rear end I left it off. Looks like member 70cc

Nice looking trailer. In my experience/opinion it might be even better if the winch were raised so as to have the strap be parallel to the ground.

I agree, but the winch handle would hit the crash pad if any higher.
I guess this was the compromise location, never seen this combo before myself. |
