Does anyone have problems with the trailer flexing and pulling on the bow eye hook on the boat as you go over the top of the ramp.

My aluminum tri axle trailer seems to flex alot as i pull and put the boat in the water. As the trialer and boat go down the ramp the boat wants to rise off the bow stop significantly. It is a instigater trailer. I hate it and i am afriad it will pull the hook of the front of the boat. its a 30 ft cigarette.

Put another strap on the bow eye going straight down to either the bow stop or the frame. The boat won't budge from the bow stop going up or down the ramp

Set the trailer up forward till you achieve 75% of tongue weight.

Yes, aluminum trailers are great for longevity IN SALT and for short haul.....but they have their inherent weaknesses...

If it's short haul....set it foreward

what do you mean by short haul.
The boat is as far forward as the trailer will allow.
As far as another strap ,I dont want it to pull on the bow eye hook. I feel it could pull it out after time. It pulls that hard. I have been loosining the winch once i get it out of the water before it goes over the hump so it does not pull on the eye hook. The boat doesnt want to slide off at all but would rather have it tighten up without pulling. Does a myco aluminum do this or are they stronger. I think a steel one may be better for the strenth. Is the trailer that much of a P .O .S.. I kind of think it is.

When I first putting the boat on the trailer, mine did exactly what you are describing. I found out that I was not winching it up high enough on the bow roller. Don't know if this is the case with yours, but another idea any way. Do you have room to move winch higher, so that bow roller is further forward and higher?

It is up higher pulling straight and upwards a little. The winch does not pull downwards . It was to low, but i fixed that, I got a new winch stand so i could have full adjustment.

I have a Tech sun also. It does flex. The boat has never wanted to slide off. Best fix is to not look. When moving down the hwy i have weight on the bow stop. I way lessens flex and bounce. I think your trailer came with a bow catcher and not a front roller?

Aluminum trailers flex no matter who makes them. The only way to get a trailer that supports your boat correctly is to get a welded, heavy, tubular frame steel trailer IMO. For salt water use, get it hot dipped galvanized.

Shouldn't have to be concerned with pullin the bow eye out, but even a myco steel will flex some cresting the ramp.

Don't worry about the bow eye. It is WAY stronger than you think. (don't ask me how I know)
