Having spent countless hours in a fruitless search I have not been able to identify my boat. The registration shows a local naval yard (Lisbon, Portugal) which has since gone out of existence and left me to guess at what model this boat is based on. The closest I got was the Alberg 30, but on closer observation some details just don't convince me. I find it hard to believe that this is a one model, local product, due to the quality of craftmanship.
Umedsó is 9,40 meters LOA, 2,80 meters wide and has a draft of 1,52 meters. She weighs in at 4,16 tons (!!) and was built in 1980. There are no markings save for the cove stripes.
The boom is made by Skarvens (Swedish rig maker...), the winches are Baron and blocks are Barton. I'm inclined to believe that she's a nordic boat, but my search has so far proven fruitless. Anyone have any suggestions?
