Pickup truck drowning at launch ramp?

Just wondering what some common wheel or tire diameters are for boat trailers. Reason I ask, mine are huge, and seem to put the trailer frame/boat so high up, that I have to back down the launch ramp til my front truck wheels get wet. And its just a lil standard rear wheel drive pickup, so I worry about losing traction and going for a dip. I've seen tons of hilarious videos on youtube of guys with 4-wheel drive sliding in. If this happens to me i'll never be able to laugh at these videos again so for pete's sake help me out. :facepalm:

Re: Pickup truck drowning at launch ramp?

How shallow are the ramps you're launching at?

I used to launch my boat on a trailer with 13 inch tyres from the back of my sedan which had 18 inch rims and lowered suspension and i never even had to get the rear tyres wet.

Re: Pickup truck drowning at launch ramp?

I think they places i go to have pretty standard ramps, maybe a bit shallow. But the bottom of the boat is more than 2 1/2 feet off the ground if that gives any reference. All I know is that the bed of my pickup gets wet . Its actually pretty funny :). And i've had to walk across the hood, onto the roof, into the bed and jump to the boat to tighten it up properly :facepalm:. I'm cracking up at myself while I write this, by the way. Its a homemade trailer (not by me), so I expect some problems.... just stuff i'm going to have to deal with since i got my heart set on using this one. Not necessarily looking for a root cause of the problem, just curious about tire/wheel sizes.

Can you post up some pics of your boat and trailer? If we are able to see it we can help you out more :D

Re: Pickup truck drowning at launch ramp?

is this the motorcycle trailer with springs and axle from a pickup? I really wasn't trying to pick on you when I said to find a boat trailer.... you have posted several questions about how to make it work.... By now you probably could have found a decent BOAT trailer for less than you'll spend just on springs, wheels, and tires for this one. Then you'll be launching with your truck on the dry instead of filling your rear differential with water.... btw if you have any water in the rear at all change the lube and flush the tubes or figure on putting a rear end in the truck

+1 on the boat trailer. I've had boat trailers that were a nightmare to set to fit the boat. Trying to get a homemade set up right is worse.

Just to answer this question, from 18 - 25 ft. they are typically 14s.

If you are dead set on using the same trailer...could always extend the tongue...of course you will have to reposition the boat in order to achieve safe weight distribution if you go this route, pictures are worth a thousand words, so lets get some pictures of your truck and trailer setup!

The first thing I would try would be receiver hitch with as much drop as I could get.

Re: Pickup truck drowning at launch ramp?

Even if the tires are to big and the axles are on the wrong side of the springs and the springs are to big, I'm not sure sure you should have to get that far in the water at a normal ramp. I'm wondering about the bunks and how tall they are in addition to all the affore mentioned things? Really need some good pics to be sure.

other way around... Adding drop to the tongue raises the back of the trailer, and makes his problem worse. If you want a boat that is easy to unload, you need to add LIFT to the tongue, flip the drop hitch upside down. Raise the front of the trailer, and the back drops...

Re: Pickup truck drowning at launch ramp?

actually neither of those methods will help a too tall trailer BUT a LOW tongue is the better situation... the ramp is sloped and the water is level.... lowering the tongue gets the boat closer to level and allows it to float further on to the trailer without backing as far into the water

Re: Pickup truck drowning at launch ramp?

I spent about 20 seconds on Los Angeles C/L and found this boat and trailer for $50. Something like this, you just advertise the boat for free or take it to the landfill and you have a MUCH better trailer and all your boat ramp problems go away.

Re: Pickup truck drowning at launch ramp?

you should never get your front tires wet and seldom if ever get the rear ones wet.

Is your axle under the springs? that may be the problem. Bunks too high? Homemade frame with cross-beams straight across instead of dipped down for the keel?
Consider rollers, too.

+1 this!, the windshield alone could be sold to cover the cost of disposal

Re: Pickup truck drowning at launch ramp?

Hopefully the OP will be back tonight with some answers.
And because we sometimes assume the obvious, I'll add another question to the pot!

Are you backing the trailer so far into the water because you're attemting to completely float the boat off of the trailer, or are you just trying to get the stern wet, and giving it a real He-Man shove to get it to slide off?

Waiting for the Pix! :)

Re: Pickup truck drowning at launch ramp?

smokeonthewater is trying to ruin my hopes and dreams of getting this thing to work hahah. :D Smoke, I agree with you 100% that I could save alot of time and money by finding something like you pointed out. But for me, that would take all the fun out of it. Plus, I'm stubborn. Set on getting this thing to work come hell or high water (literal high water :facepalm:). I'll post pics tomorrow but I can tell you the axle is already above the springs, and its a jon so it sits as flat as it can. I am not new to boats, but I am new to trailering/launching so I can only assume that the few ramps i've been to are a typical grade...... Smoke is gonna have a field day when I quit having problems and post some pictures of the finished product. IBoats Forum Party! Bowfisher finally shut up! :)

Re: Pickup truck drowning at launch ramp?

If the boat ramps you deal with are anything like they've been putting in around me lately, nothing other than a super long tongue will keep the truck dry.
At one lake here, with my 2 wheel drive, 1996 F150 Super Cab with an 8' bed, towing a 14' aluminum Starcraft flat bottom V hull on a bunk trailer with 8" tires, drop axle, and a boat that sat so low on the trailer I had to fully tilt the 9.9hp motor to go down the road, my front tires had to be wet up to the rims just to get the boat wet enough so I could push it off the trailer with a lot of rocking and getting my feet wet.
I think it would have been easier to just dump it on the ground and slide it in the lake next to the ramp in the mud.

They keep making the newer ramps shallower and shallower. I can back down most ramps here to the end of the ramp and still not submerge my rear axle or wet my brakes and have a car length of water in front of me.
I solved the problem by installing a longer trailer tongue, one that gives me about 8' ahead of the boat when loaded. This is still often not enough to not get my front tires wet. The best ramps are the old ones, those that were just gravel or seashells with no concrete ramp to end and get tires caught over the edge. The trailer I have now, a Shoremaster, probably the lightest trailer, came to me with both rear wheels ripped off, someone backed over the edge of a ramp and both spindles were ripped from the axle tube when they pulled it free.
I built it a new, heavier duty axle and have been using it for a year now. I just found a clean used set of roller bunks which I hope will aid in dealing with shallow ramps. The only good thing about these new ramps is that you can wade out in just a pair of 12" boots and not get wet, but for launching a boat, they're about worthless.

Another location, with similar ramps, also has courtesy docks made from aluminum, when you back in, the docks are 6' above the boat, being your launching in a river, the boat almost immediately drifts under the dock. The far end of the docks are floating but they put a raised section the entire length of the ramp. I guess if they ever get a 6' over normal high tide flood tide, they're all set. The rest of the time it's just a hassle.
