“SIENNA” is an 87’ Doggersbank Superyacht with exterior and custom interior design by Vripack, built by Kuipers Woudsend Shipyard in the Netherlands and delivered in 1986. The superyacht accommodates up to eight (8) guests on board and has crew accommodations for three (3) crew members including the captain. Her twin MAN diesel engines provide a cruise speed of 10 knots and a top speed of 13 knots. She carries 1,200 gallons of water and 6,880 gallons of fuel.  

In 2012 she received a major refit involving the qualified Vripack team. The extensive refit took place in San Diego, California, and included an award-winning, custom interior designed, built, and installed by the original architect studio Vripack. In 2023 she further benefited from significant updates including Main Engine Rebuilds and New Air Conditioning Chillers. (See updates below)

Doggersbank

Named after a large sandbank in a shallow area of the North Sea. Doggersbank was brought to life in 1968 by Dick Boon, founder of Netherlands-based design house Vripack. Since its inception in 1968, the Doggersbank offshore has become a moniker for explorer yachting.
