Anderson 40st all stainless weight 5 kg, Lewmar 40st weighs 4.9 kg in aluminum (3.52 ounces lighter) and upto 6.7 kg in stainless or bronze. Anderson is probably the most durable winch available and very easy to service. Anderson recommends 2 yr service interval as opposed to most others which are i yr. So the weight is very close but the price might not be. I own 2 Anderson 40st and two 28st and couldn't be happier.
