I hope that your boat is 12m or less as the rate jumps significantly at 12m upwards, don't think about entering 12.1m if it can be avoided. I think it began in 2019 and rates haven't changed.
10m - 12m is 33 euro per month
It's 8 euro per metre per month above 12m
12m for 6 months would be 198 euro
12.1m for 6 months would be 580.80 euro
Avoid launching late in the month and lifting early in a month as you pay for a full month, even if only afloat for 1 day.
e.g. Launch 31st May and lift 1st June requires payment for 2 months. Not great if you discover an emergency just after launch.
Online system is pretty poor and method of payment is confusing for new applicants who don't speak Greek. Payment is actually pretty simple when you work it out as your get a number that links your TEPAI record to the payment system.
The e-TEPAI part is a way of getting your boat and owner/user details into the system and eventual proof of payment via PDF once you complete payment.
I usually pay in a bank or Post Office rather than bank transfer.
+1,
mine is 12.98m 100little a month (103 or something like that)
You can DIY the docs online. I'd suggest you do the first time with someone that's done it before, UI is not great, text not clear, frankly a mess!
