Help with land based winching

Hi all.

I am in the process of building a boat shed for my 535 Ribtec with a 90hp 2 stroke Yam.

The ramp in has a slight incline and I want to install a simple electric winch to aid getting it in.

Boat, trailer and engine are under 750kg and it's for horizontal pulling not lifting, does anyone know how to calculate the winch capacity I need? EBay is littered with winches, I just don't know which one to buy.

Many thanks

The physics is simple trigonometry- you need to know the angle of the slope. The smoothness of the surface will be hugely important though. Do you actually need electric though?

I'm sure it would, but surely OTT .
I reckon there would be enough grunt in a far cheaper one for say less than 100.
I am considering doing same and the key issue/need as far as i'm concerned is a remote control - preferably wireless as that means I can wander about as i pull it into the shed.

That is silly money, this would be plenty if cable length is enough. I have the one below on my trailer for winching boat on. For another 20 quid you can get the 3500lb model if you prefer.

Yes absolutely needs to have a remote control.

I was thinking something like this;

It's only a gentle incline with a smooth surface.

Nice bit of kit.... i have gone with a scaffold winch as that allows me to move it about on the back wall of the garage - helps with the positioning of the rib. It isnt perfect as I have to unbolt it to adjust the angle on occasions, but Im happy and I always have a handy grab rail along the back wall for when I too old to stagger across without assistance
The bolts and backing plates through the rear wall were an interesting installation!

You could flip this on it's head & mount the winch & battery on the trailer. You can then winch the trailer into the garage under its own steam. You can also use the winch to self recover the trailer up slipways. Just something to think about.

yes i had a post with loads of good info about a year ago ,but when you start talking to the winch suppliers most of them may as well say to you " well i have a shed load of chinese winches but hav,nt got a clue what there for " ratings mean nothing one chap even suggested to me the rating was for winching downhill
i bought a 900 kg al-ko manual winch ,braked ,, you winch it down and you winch it back ,brilliant no batteries required , handles long enough for a child to do it much safer ,infact i bought a second one today on ebay £60 brand new
