Feadship’s Royal Van Lent shipyard has announced radical plans to expand its premises on Kaag Island in the Netherlands.

Due to limited options around the yard, the company has decided to extend underground in order to build even larger yachts over the coming years.

The first part of the expansion will see the hall doors widened and the dry-dock door extended 5m to provide the space necessary to fit the long propeller shafts of larger yachts. This part of the project is due to begin in August 2012.

The yard is also going to rebuild one of its two slipways which is currently set on wooden piles and unsuitable for yachts over 45m.

Royal Van Lent will also widen the locks in the nearby city of Gouda from 12m to 14m. The bridges in the towns of Oude and Nieuwe Wetering will also be extended to the same width, with an expected completion date of 2012.

The total redevelopment is expected to cost several million Euros.
