Trailering set up issues

I am posting this for a friend since my sailing days may be over now.
He has a 17 ft (don't know the name but pix attached). He bought from somebody and it included a trailer. Shallow water, flat bottom keel.

He is having a devil of a time trying to set the trailer up properly.

If the boat is hauled from the water, it wants to tip back.
The only thing holding it on the trailer is the winch strap. We moved the winch tower forward, hoping that that would solve the problem, but it really doesn't. Now, as you can see from the picture, the bow tips down, and the keel actually rises 6 inches off of its flat bunk. He has adjusted everything he can think of. Yet, when I look at images of other boats on the net, they all appear to be positioned at the same general location on the trailer. Any help appreciated.
regards, Rich

First attach to tow vehicle, on level ground.
Then set keel flat in its slot or on its bunk.
Adjust side bunks equally.
Position boat so that it rides with about 10-20% weight on the tongue.
Adjust ball height to ride slightly bow down.
Adjust winch support to fit.
Use truckers strap over the cockpit near the companionway to the trailer frame.
You should float on. Being light on the front when pulling up the ramp shouldn't bother anything.

What you also need is a roller support for the bow. This way the bow rests on it where you want it to be for proper balance, and you do not have to bring the bow all the way to the front. I would set it up on the first crossbar. Overton has a good selection. Trailer Rollers | Overton?s
Pick the shape that best matches the boat hull in the front section, and get a proper bracket. It is a fairly easy job.
Your friend's boat sits way too much forward the way it is now.

Be kind, for everyone you meet is fighting a hard battle.

Re: Trailering set up issues

Honestly the problem you are having is it looks like it was a replacement trailer for the boat.

I'd remove the dolly wheel, slide the winch support forward, slide winch up.

Also a bow support roller would help.

Also said, get the keel secure and FLAT on that bunk below. THEN adjust the bunks up to match the sides of the boat.

You DO need to get 10-15% of the total up weight on the ball of the tow vehicle. It's also essential that the ball match the height of the trailer, keeping the whole package level.

Finally don't transport with outboard on the transom (lots of reasons for that, but the most obvious is it's a VERY far out position, that makes the trailer act like a fulcrum and you'd be amazed how little weight it takes to tip a trailer).

Finally it looks like it's a Vagabond 17 Maybe this picture will help you to see what another one looks like on a trailer.

Re: Trailering set up issues

Look at shnool's picture , his winch is pulling up on the bow yours is pulling down . You can look at any boat (sail or power) and the trick is to have the winch pull upward into the bow guard(snool's guard is over the bow eye , most are under)

Also if the bow isn't tight to the guard it causes the trailer to flex & the boat to bounce on the trailer and can be very unstable on the road.

Re: Trailering set up issues

I would never use the winch to hold the boat to the trailer. Living at the shore all my life, I have seen -many- boats come off their trailers when they either bounced too much or the winch let go. You really want at least 2 inch wide rachet straps holding her securely forward and stern. I use the big truckers straps that 3 inches wide for my 3200 pound full keeler

Re: Trailering set up issues

MIne sits on the trailer much as Schnool's. Bow pulls up, although I do not have a full keel. I also use the large straps in the rear. Haven't seen any put on the fron before, may not be a bad idea though.

Re: Trailering set up issues

I think the most cost effective way would be to shorten the bunks by cutting 2' off the front of them and installing a large roller to support the keel at the first crossmember behind the winch. The winch mount needs to be redone to pull forward rather than down.
