The Biscay ferries are highly recommended! I think the Portsmouth-Santander route is classier (ie a classy restaurant*, more of a cruise ship feeling) than the Portsmouth-Bilbao** but both are perfectly fine for Mogs - often joined some very interesting machinery on both routes!

* make sure you join the queue to book a table for dinner after you get on board - no prebooking allowed! At least the restaurant on the ship I used was next to a bar so the queue is amicable. The restaurant has always been packed out on the times I've been on the ship.

** the upstairs on-deck cafe is great for breakfast before docking!
