If you're sailing to the Netherlands from the UK and have purchased Red Diesel please be aware of the following advice.
Although it is still legal to purchase red diesel for use in pleasure craft in the UK, this is not the case in many other EU countries. Boaters who have filled their tanks with red diesel in the UK occasionally experience difficulties whilst abroad.
Take a look at the latest statement on the RYA website and scroll down the page for specific advice for boaters visiting the Netherlands:
It simply states that you can fill up your tanks with red diesel, but not take more fuel with you than the amount [capacity] of your tanks. You have to keep receipts and be able to show the receipt, which can’t be older than 1 year old. On the receipt should be printed “the difference in tax between white and red diesel is paid by [to] the UK Government (the 60/40 notice)”.
