Thanks Robin and Paddy.
Yes, been having a little creative burst of late Robin !
Yes Sea travel in those ancient vessels must of been very risky, at least with a Trireme I would think, assuming you had a full compliment of healthy rowers, (Nope not slaves as Ben Hur would have us believe) it would make the Trireme capable of a good turn of speed when needed, not like the huge Grain ships sailing between Egypt and italy and reliant on wind, oh how they must of just wallowed in even anything but the calmest of seas.
