Jachtwerf Allemansgeest is a historic boatyard and marina situated on the border of Voorschoten and Leiden, at the junction of the Vliet and the Korte Vliet.

It lies within the Hollandse Plassengebied and along the staande mast route, making it a well-positioned stop for cruising boaters.

The fully renovated yard offers new and used boats for sale alongside a marina with high-quality facilities, including covered berths that shelter vessels from the elements. Winter storage is also available on site.

The yard serves as a general hub for boat enthusiasts, with a team handling maintenance and repair work on yachts.
