You are a part of Het Zinkstuk when you are either a member or a contributor. As a member you can participate in all swimming and waterpolo practices as well as all the activities. As a contributor you can only engage in activities.

The membership means a lot of fun and an excellent way to get to know other people quickly.

Membership is continuous and can be terminated throughout the year. Membership will then stop at the next unsubscribe-date.

Yes, that is possible if you study at another higher education institution in the Netherlands. It may be that you are first placed on a waiting list, so that it takes a while before you can become a member.  We suggest to sign in but don't buy a sportcard at olympos yet, buy the card if the board tell you, you can be member. For more information about the waiting list you can e-mail secretaris@hetzinkstuk.nl.

You can subscribe via the registration form.

The costs for a full season 2022/2023 are displayed in the table below.

A new member also pays a one-time registration fee equal to the costs of the KNZB-contribution and potentially the starting fee for a start license.

KNZB contribution wil be deducted every half year and will be payed up front.

Olympos sportscard. When you are a member of Het Zinkstuk, it is obligated to own a 6 or 12 months sportscard of Olympos (the Olympas).The Olympos sportscard has to be bought via the sportcenter Olympos and then has to be registered to Het Zinkstuk.

Contributors always pay the contribution for the entire season, despite the time of registration. This means that if you register as a contributor between August 1, 2018 and July 31, 2019, you pay the entire contribution of 2018/2019.

Members
If you become a member between February 1 and August 1, you only have to pay half of the training fee for that season. You do pay the full KNZB contribution, registration costs and eventually the costs of a start license
