Neighbour wants me to upgrade his manual windlass to a new electric one this winter. Is there any way of checking whether his chain is properly calibrated stuff and will fit other than finding out once it is fitted?

No way of finding out apart from trying it on the actual gypsy the chain is going on. Of course some will give you the measurements of calibrated chain.
When purchasing anchor windlasses, its normal to either send them a sample of chain or send the gypsy to the chain manufacturers.
However if he already has a windlass, the manual one, then it's a very good bet his chain is calibrated, if it fits that old one fine.
I've just gone through this, sent my new gypsy to chain manufacturers to have the chain checked, all 90 meters of it!

Any chain made by a reputable company is calibrated. 'Un-calibrated' is code word for made in china.
Just measure your chain very carefully i.e use verniers not MK1 eyeball, and fine the wire size and the internal length of each link. Give those 2 measurements to the winch bloke and they should have no problem sizing a gypsy to suit.
Wire size - the diameter of the wire bent to make the link.
Measure a few links just to make sure you don't pick a weird one. All measurements should be within 0.5mm for chains up to 10mm odd (less if DIN Standard), if they are not you have either worn it a bit much or it is chinese made (shocking calibration, if any, out of there usually)
Don't go chopping your chain up there is no need. That's the 2 measurements we ask for and have no problem sorting which gypsy, it's very easy. Make the buggers work a bit for their bucks /forums/images/graemlins/smile.gif
