Pulling a boat up the launch ramp

So last weekend I was able to get out to the lake for the first time with the new boat. The Pathfinder has been a great tow vehicle so far and the only thing I was really curious about was how well I'd be able to get up the launch ramp. Back in '08 when I was buying the Path, I read around quite a bit and most people said that 2WD was sufficient, just take it nice and slow.

So last Sunday I was able to test it out for the first time and I did have traction issues. I took it as slow as I could, but the tires just wouldn't keep from slipping. I did have four of the passengers in the boat still and I was about to have them move to the bow which I think would have taken care of the problem, but two guys nearby saw I was having trouble and came over. They pushed on the back of the Path and that was enough to keep from slipping and we drove up the ramp.

I posted a message on the boat forum asking other people what they do and several suggested that I use 1st gear. I wasn't sure if this would make any difference since my problem was not that the tranny was shifting. Last night I drove around the neighborhood and did a test. I wanted to see if the throttle response in manual mode 1st gear was any different than being in Drive. From a stop I shifted over to manual mode and down shifted to 1st. Then I pressed the gas several different times, slowly and intermediately. I then switched back over to Drive and did the same thing. In doing so I was not able to tell any difference in the throttle response. 1st gear manual mode seemed to be just as responsive as Drive. Obviously it would not up shift to 2nd, but that was not my issue when I was on the launch ramp at the lake.

So after this test, it seems to me that being in 1st won't do anything to resolve my traction issues as the throttle response doesn't appear to be any different. Does this jive with anyone elses experience? I think I'm just going to have to have a couple of passengers move to the bow or get in the Path with me in the future. What do you all think?

Start with the main factor when it comes to traction: Tires.

What type of tires are you running and how much tread?

Agreed... Tires & maybe tire pressure :?:

I pull a 19' cuddy that weighs 4200# on the trailer and I have no problems pulling up a ramp. I've got Yokohama geolanders that still have about half the tread. I don't leave anyone in the boat when pulling out. 4wd does help on a slimy ramp

go 4wd next time, if you're still having issues try airing down the tires a bit too, give you some more surface contact between the tires and the ramp...

But according to his sig, he's 4x2.

OEM General Grabber's. They are nearing replacement, but still have tread left. See below.

Can anyone confirm my test regarding the tranny?

1st gear works as you described and there's no difference between locking it in 1st manually besides the fact it won't upshift. I'm not sure why they would recommend that....it really doesn't make any sense.

Well worn tires (those are even looking dry rotted even) certainly won't perform well. Since you need tires anyway, I'd probably start there.

Just as a follow up for anyone else who might be in the same boat as me (pun intended :-)), we were out this past weekend and I moved my passengers up to the bow and that was enough to make the difference. No tire spin at all this time.
