Default Positioning boat on lift, how far "back" can I position in?

I back in on the lift, it's a 21' walkaround. Would like to position my boat as far "back" on the lift as possible so the motor and transom is close to the dock, that was I can access drain plug, engine, etc to do some cleaning and routine maintenance.

What way is best to determine how close I can get the boat to that position? I don't want it to be out of balance or tipping out (if that's even possible). Thanks for any tips.

PICTURES!!!!!!!!!!FIRST NORMALLY, the ass is the heavy part and should not hang off further than 2 feet from the end of the bunks. preferably at the edge of the bunks. ESPECIALLY ON A SMALL BOAT.

Thanks that's good to know. Will get some pics this weekend. Do you mean 2' from bunk end to transom, or bunk end to back edge of motor, i.e. the prop?

Assuming you are talking about a 4 post lift, in general the back bunk should be about a foot or two from the transom.

The tension on all the cables should be the same. You can twang the cables like a guitar string and they should all sound the same.

If you can find it out, what you need to know is the center of gravity (COG) for your boat.
I just went through this and I'm STILL not 100% certain that I'm in the right place! Yet my boat is extremely bow heavy.

There's a tool you can buy to measure the tension between the cable if the bang and twang method doesn't work for you...

Post up some pics!

motors dont count! Hull does.

Got some pics. I'm about 20" from the edge of the bunk to the edge of the transom.

I'd say another 2 ft for temporary cleaning and maintenance, but not everyday. It also might not be a bad idea to tie off a line to that mid bow cleat down to the crossbars if you will be standing on the back of the boat.

First off what's your lift rated for? If the weight capacity far outweighs the boat then it really doesn't matter if not then grab the forward cables and squeeze and do the same to the back and the tension should be similar. In other words you don't want one side carrying all the weight.

So there's no chance of the hull developing a 'hook' with that much hull/engine overhanging the bunks? If the boat was on a trailer I wouldn't want that much overhang.

Positioning looks good

I cringe every time I see a boat on a trailer or lift without a properly supported transom.

It's very simple your lift is designed to equally share the weight of the boat between all of the cables. You can easily feel the load on the cables with your hand bu just squeezing the up and down cables with your hand.

16k pounds lift, and boat is a tad over 1/4 that with full tank (~103 gallon).

Do you have any fear of hitting the crossbeams and bunks when you back in?

for a few bucks (OK, maybe a few hundred) you can get buy and install (or have installed) work platforms that allow you to service the transom area and the outer side of the boat.......

nope, that aspect is dialed in (markings on poles, etc).

Thanks! I just googled the image of that ("boat lift work platform"), that's exactly what I need. I'm on a borrowed lift till I figure out my own storage situation, but the owner will be cool with me putting that on (he's a friend). Thanks again.
