I am afraid you are wrong as i wrote to them and received a full explanation, including the expectation that i should be grateful that brittainy ferries are saving the planet

They are slower. Look at the specs.Don't think so.
I took the same (eco) ferry, and it was an excellent ride, but longer time from UK to ES and shorter time coming back. Same boat.
They are slower. Look at the specs.
It's all relative but the grub on board is reasonably priced. In particular, the three course buffet dinner at (IIRC) 20 Euros is great value as the portions are large. I take large bottles of mineral water on board but otherwise, I buy what's there. It could be a lot worse TBH.The boat docks in Bilbao at around 08:00 then leaves for the return journey at lunchtime. This suits me perfectly as I can get on the road early in Spain to head south and there's no rush to check in early for the return. I also like the late boarding leaving Portsmouth as I can go to my cabin and sleep.
Once on the boat we're trapped and will be taken advantage of regarding the price of food. I'll be taking food and drink on board for the whole day crossing.
For me it's a great way to get close to where I want to be and is much cheaper than a long haul ride on French Autoroutes.
If you look at the Portsmouth crossings to the northern French ports, they all tend to dock at a similar time in the morning irrespective of the length of the route, so I am sure you are correct.I'm sure they are slowing some boats down so to arrive at a decent hour.
Who wants to debunk at 03:00 am
That's not correct. The return journey from Spain to Portsmouth is still only 26 hours.The reason they are slower is the new ferrys are eco. The sailing from Plymouth is old fashioned diesel.
The old ferries are sailing happily across the med from italy
Taking the Plymouth service, as we did one year, gets you off the boat at 6pm, so there's not really much time to get anywhere that day. I'd rather have an extra night on the boat (saving a night's accommodation in Spain) and arrive in the morning with a whole day on the road ahead.
Unless you is Doc who gets up at 0300 , has dinner at 1100 and t’tea at 1600 and is in t’bed by 2100.the Pont Aven sailings from Plymouth leave at 1545 or 1645 and arrive the following day at 1300 or 1400. As you aren't getting dinner before 8pm you can ride quite far e.g. Pamplona or Leon are an easy ride.
Don't worry about me I'll be fine. And 10pmUnless you is Doc who gets up at 0300 , has dinner at 1100 and t’tea at 1600 and is in t’bed by 2100.

Agreed, I rode down to Salamanca on my 350 ADV, and got there before 8pm in September 2023.the Pont Aven sailings from Plymouth leave at 1545 or 1645 and arrive the following day at 1300 or 1400. As you aren't getting dinner before 8pm you can ride quite far e.g. Pamplona or Leon are an easy ride.
