Good morning, Marek and BelSkorpio,
For uphauling of big sails, you might consider the Easy-Uphaul, sold by Chinook dealers and shown here: http://www.chinooksailing.com/produc...roducts_id=146
. I use one on my 9.8m and it makes uphauling very easy.
You could also Google on Easy Uphaul to get extra information.
Hope this helps.
