i'm looking for some forum experts if possible on this before i toss 400 quid away potentially on a DL tw9000 (a 3000lb winch)..
SEE HERE- https://www.dutton-lainson.com/206339.pdf
i'm having a hard time believing the winch will have enough power to pull my boat upto the snubber with authority. All the maths and data forms i've looked at suggest it will struggle, not what i want from 400 quid winch!
unfortunately there doesn't seem to be an industry standard method for winch rating. my current 3500lb winch will pull 1700lbs when on the last layer of wire and at 190amps, i.e near the snubber and assuming you have an amazing power source (forget car battery at those amps). i know you need to factor in the slip angle and the advantage rollers give though, that is where it gets tricky for me.
that 1700lb i mention specifically says is a rolling load which will be road or rail wheels depending on the online winch chart you use. is that better or worse than our roller trailers? my logic being i can't push my boat off the trailer on the flat, but i can push the boat on the trailer so i'm assuming (dangerous!) a rolling load these charts mention is easier by a factor of X than loading on a roller trailer.
this tw9000 is actually a 3000lb winch, the snubber part it pulls also circa 1900lbs according to their own chart on the link above. i'm having a very hard time convincing myself it is enough to do the job with ease, especially if i need to stop and start for some reason near the snubber.
what worries me is this- i once tried to use my 3500lb electric winch to pull my old boat (trailer and boat 2200lbs) and trailer up an incline of 18 degrees (very very steep private slipway) and to say it was struggling was an understatement. i actually gave up winching it up and went and borrowed a jeep from the yard to get it up the slip. in theory i was well under the limit but it sure didn't sound like it when i was doing it! hence my concern for doing this in "comfort"
i'm as confused as a newt as they say, does anyone have experience of this before i pull the trigger?
BTW...the ribcraft is 2700lbs confirmed full tank with usual kit on board.
