Help: BoatHouse Winch

Slow is fine. Doing it by hand isn't fast. That's for sure. I forgot
to mention, we need to let it run down the slope into the water under
control. I don't know much about winches and I wonder if this is a
normal feature or something I need to pay more for?

please excuse me if the formatting of this isn't so good. I'm using
google from another computer.
thanks...thehick

Winches lose about 12% of their torque per wrap of the strap around the
drum. With a 25' strap to wind around the drum and a 5 foot rise ... hmmm
.... a 12 volt winch does not sound feasible to me ... but ... you know how
much the PWC weighs and what sort of drag there is e..g. cradle on tracks.
For what it's worth, winching with offroad jeeps typically involves 2
batteries plus a heavy duty alternator.

How about overnight, you pull it up using your current winch but just far
enough to lock it to something like say a chain that's attached to something
farther up in the bush

maybe i didn't write clearly...i'm pulling a pwc on a trailer out of
the water up an incline ramp into a boat house. right now
we do it and an even heavier 16ft boat with a hand winch.
no strap. cable. linear pull about 25 feet. vertical maybe 6
feet but probably less.

the first response suggests it will work just fine, but i forgot
to ask about letting it down. i don't have any experience
with electric winches. do they all have a reverse? so i
can more-or-less let the line out under control as the
pwc (or even the boat) go down the ramp? this part
is critical as then the job can be a one-person affair instead
of requiring 2 or more.

Ok ... you're pulling it on a trailer with a hand winch. I'm suggesting use
the same technique except how about skids, whatever, instead of the trailer,
and don't pull it all the way to the boathouse ... just pull it clear of the
water and secure it to a chain ... or maybe even that cable ... that's
secured to something else.

It sounds to me your specification is that the solution meets the insurance
company requirement.

A couple of ideas from "down under"
1) There are parallels between what you are trying to do and launching /
recovering a trailer boat. You may need too much "rope" ( cable, strap etc)
for a trailer winch, but they are cheap, 12v, and plentiful
2) Have you investigated a vertical capstan? Much cheaper than a winch, and
no limit on the length of the rope. No " " here, it's just plain rope.
Again, 12V is pretty standard . I suspect it will be a 2 person job
whatever you do, if only to guide the trolley and attach whatever you use to
stop it rolling back when you let go of the rope.
3) If the capstan idea works, you may be able to figure some way of
converting one to mains voltage operation - but it may still be cheaper to
stick with a 12V capstan, battery and charger.

thanks for the idea. i'll check into it. i still
don't have a solution.
