Registering your boat for use on Loch Lomond

The Duncan Mills Memorial Slipway is now open from 8:30am – 9pm (7 days).

Byelaws were introduced on Loch Lomond to improve safety, reduce disturbance to wildlife, local people and visitors. Some byelaws apply to all users of Loch Lomond however, legally, if you are using motorised vessels on Loch Lomond you’ll need to register it with the National Park Authority and display the registration number on your vessel.

The slipway is operating largely as it did last summer with appropriate COVID-19 protection measures in place. We are asking everyone to adhere to the guidance at all times to keep yourself and our staff safe.

To help reduce queuing times we encourage all Loch users who need to apply for a new registration and those who have yet to re-register for 2021 to do so using the following methods:

New registrations

  • If you have already sent a completed new registration form and are waiting on receipt please call – 01389 722030.
  • If you have still to apply please download the form at the bottom of this page. Please bring the completed form, along with your ID to DMMS.

Re-registration forms were sent out at the beginning of the year. Please complete this form if you wish to re-register your craft.

  • If you are intending to launch from Friday 23rd April please complete your form and bring it with you on the day, where you will be issued with your 2021 annual mark.
  • If you are not planning to use the site within the next few weeks please post your completed re-registration form and return it to us as soon as possible and we will send out your 2021 annual mark.

If you require further assistance please call us on 01389 722030 or email with your enquiries.

When you arrive at the Slipway to register or re-register, you’ll need to bring a few things with you…

What you’ll need


If you are registering for the first time or re-registering without your renewal form, you’ll need to provide proof of identity, either in person or by post. This can be either a UK passport or driving licence (or other form of photographic ID), supported by a utility bill or credit card statement containing your address and phone number.

If registering in person your ID must be originals, not copies. If you are registering by post or email, please scan your original document and include a copy with your completed form. We cannot return scanned copies but they will be securely destroyed once your identity has been verified.

Your fee

  • Annual Operations Payment (voluntary)– we’ll ask for a voluntary payment of £30 at the time of registration and re-registration. This contributes towards registration number materials, the Loch Lomond Rescue Boat and services on the loch.
  • Registration numbers –should you choose not to pay the annual operations payment, £6 (plus £2 postage if registering by post) is required to supply the registration number materials.
  • Launch fee– for any craft using National Park Authority launch facilities. The fee has two options, an annual launch fee (£80/craft per year) or a single use (day rate) fee (£20/craft).

Please note: Use of the slipway for non-powered vessels is free, provided they are not launched using a vehicle.

How to Pay

At the moment we are only accepting payment in person – by credit or debit card. Bring your completed form to Duncan Mills Memorial Slipway.

For security reasons we are no longer able to accept cash payments at the slipway.

What happens next?

When you have registered and paid, you will be issued with two annual marks, two full sets of registration numbers, letters and backing sheets, a copy of the byelaws booklet and a card to assist you in the recognition of buoys marking the navigational hazards of Loch Lomond.
