Sadler 25 best lifting sling positons

[Praxinoscope]

I am doubling up this post on the Sadler and Starlight forum.
As we lift in and out each year, but not allways the same crane driver/banks man, Ithink it would be useful to mark the optimum positions for the crane lifting slings on my twin keel Sadler 25, I have experimented with slightly different points over a couple of seasons, but as there is allways a time shortage when lifting her (all the club boats are lifted over two days) I have not really been in a position to run full experimental sling positions.
Has anyone calculated or found the optimum sling points on a Sadler 25 to ensure a level lift?

You might find someone who can tell you exactly but you may end up having to settle for some reasonable position and being ready with some markers to attach to the best spots when the boat is in the slings, making suitable adjustments. Many yards, such as mine, will fix their own markers.

As close as possible to the 2 main bulkheads is a good starting point. Not too critical with your type of boat to lift absolutely level as there is little chance of it slipping. different if it were a stinky with no keel or a long keel boat. You can get stick on lift markers from chandlers. Lucky at our club because we have a 25T Weiss travel hoist and each sling can lift independently - essential because it uses the slipway to access boats.

Not a sadler 25 but 26, so similar. I have "lift here" markers on the topsides which correspond to just forward of the mast base, and another in line with the cabin washboards these effectively line up with the beginning and end of the keels. They were present on the boat when i got her and shes lifted fine using these markers using crane or HIAB. I just put a bit of insulating tape on the rails corresponding to the labels to give a quick indication of where the markers (beginning and end of keels) are.

Thanks, the positons you have suggested are roughly where I thought they should be, I am going to mark the lift points on the toe-rail, probably with Hammerite so that they are more or less permanent.
