Merchant and ship mods?

I am playing mostly in Windhelm and was wondering if there are any mods which allow me to own ships or participate in trading activities like the shatter shields? Not one of those bigger imperial looking boats of solitude player homes but some more common longships or longboats we see in windhelm or dawnstar. Overall any bussiness or ship that would make sense for my stormblade thane of windhelm to own is appreciated.
