Actually, I don't think "swell" is the right word. And it's not "wake" either is it? What's the right word for the wavey, breaky stuff that occurs immediately around the boat?
Easter, since we moved to NI, has always meant a dutiful trip back to my folks in Birmingham. Not that it's a chore. It's an eight to nine hour slog the way we do it (ferry crossing then long drive), but it's always worth it; the journey is a great part of the holiday. This year we set out on the early crossing at 7am. Belfast to Stranraer for those that don't know.
I like an early start but there is a trade-off. The first crossing of the day is on the slow boat: small and, if you're unlucky like we were, crowded. Celtic fans and Irish dancers heading over the water to their respective competitions. But it was a fine day and one thing the tug does have over the faster boat is the opportunities to get out on deck: It's got four, fairly big exterior bits compared to the two arse-end, smoker's platforms on the speedy HSS.
Being on the sides, you get great views of both the far away and the close up. And with the latter comes the ever-changing, ghostly mishmash of the water breaking against the hull of the vessel, or is it "keel"?
