    Exclamation Jet Boat Trailer Q???

    I've got a question for all the west coast guys (or east coast guys, but it seems to be a bigger thing on the west coast) on here that have the trailers with the swing bar front hook-up. As some of you may remember I converted my trailer to this setup at the end of last season, and it made loading and unloading the boat a breeze. But when putting the boat away for the winter, we had to go up a small hill, no big deal right.....Wrong the boat actually moved backwards on the trailer a good 6 inches. So to fix it, we just sped up a little and hit the brakes and it moved forward again to where it is supposed to sit. But I'm still very concerned about the fact that it did this at all!!! This can't be normal with these setups. Also the boat has very little support at the front, i can push down on the nose with my hand, and rock the boat up and down, so I'm pretty nervous about towing it anywhere on bumpy roads or even on hills. None of this stuff can be normal with these types of hook ups, can they??? Especially with some of the beautiful boats I've seen these setups on. I really need some ideas on how to fix these issues.

    Thanks.

    Oh and here's a pic of the swing bar I threw together last season.

    A couple of things come to my mind, mostly from experience and seeing others.

    This is what you don't want to happen-


    It's best to either tighten that front chain so there isn't as much slack or change it out to a ratchet style hold down. Personally, I don't like the chain as I've seen bow eyes pulled out because the chain has no give to it.

    The other possible issue is the thicknes and length of your bar. If by chance the boat moves back and flips that bar over, it's going to punch a hole in the boat. If the bar is longer and bent down into more of a J shape, the boat will probably roll over the top without damage.

    You can strap the boat down in front or what I want to do is what I saw on a friends boat. Get a short shock and mount it on a swievel angled from the front. You don't want it strapped too tight, it will put hook in the bottom. I'll make mine and take pics when done. Pat

    The chain set up is just fine, but you must add some strap to the back of the boat. You should have some U hooks coming out of the back of your transom..........just run some straps from those U hooks down to your trailer and it will hold the ass end of your boat down real nice......

    I have the same setup as you do. I have my transom sitting with about 2" of my bunks showing, This will eliminate the bunks causing hook in your bottom, I then have a tie down strap that I hook one end to the trailer and go over the pump and hook the other end to the other side of the trailer and just snug it. (I don't have the eye's on my transom) I have never had any problems. Make sure you keep slack in the chain to the bow eye. Better to use cable with rubber hose over the cable.

    Hope this helps.

    Take the bar off and do it like this and you will have no more problems. Has Bow support and the takes the bounce and movement out. Also don't have to guess and worry about where to stop the boat, you can drive it on like a bass boat

    Found this pic on here, but this is the way mine is and no problems........

    Had the spring bar type on a trailer one time , it was a royal pain in the ass if there were any waves , it was like trying to thread a needle ,getting your fingers smashed do what Gasguzzler said and forget about it .

    I have a 19' boat crammed on a trailer made for an 18' boat, I simply don't have the room for that kind of setup, and if I did I would have done it like that in a heartbeat.

    Thanks.

    You have just as much room as i have. Come on, put the pencil and brain to work! My crank handle would not turn when the boat got up so far, cut it off and made it shorter, works good. Even if you don't want the winch, put something there for the bow to rest on. Even if you have to go back to the crossmember and put a roller there.

    Thanks for the responses guys. It seems so obvious now to strap down the ass end of the boat.

    Let's see a picture of your setup then, cause I couldn't see room to put a traditional winch setup on. I'm probably gonna put a rubber V-block on coming up from the horizontal bar to support the bow, and more importantly to keep the boat from crashing into that bar when loading and unloading the boat.

    Thanks.

    Ooops that would work even even better than a block.

    Thanks.

    With a longer floater bar it will not allow the boat to move back. Pick up a roller to support the bow down low or a bow support thet you can put down low to hepl support the bow.

    The angle of the floater bar has some to do with it as well.
