Talking to Bjorn Vang-Mathisen of Ocean Independence, he tells me that the 47.09m superyacht Arethusa is based in Port Forum, only 10 minutes away from the forthcoming Barcelona Boat Show - November 7th to 15th - and he's welcoming broker viewings.

A joint listing for sale with Craig Cadwalader of Ardell, Arethusa was built in steel by Nereids Yachts in 2008 and sleeps 10 guests in a master, two doubles and two twins. Following a price reduction in April, the superyacht's now asking €20 million.
