The Sharki is an older Amel model but, Amels are strong, well made cruising boats and have a great reputation as blue water
voyagers. their only web link is amelyachtowners : Amel Yacht Owners - Forum for owners of Amel sailboats
You should get some great info from there... eyschulman's comment about "not great" sailors is most likely due to the fact that the newer models are all push-button sailing with in-mast furling
. I don't believe any in-mast sail is as efficient as they can be but it is easy! The Sharki's are slab reefing and with new sails
should offer an impressive run against most comparable boats at all points of sail.
Best of luck!
