Back in July we had an interesting discussion about Arctic Patrol Cutters in the comments section of a note about Canadian icebreaker and Arctic Patrol vessel procurement. Bill Smith advocated the “X-Bow,” and I know I had some difficulty visualizing how it would react in a seaway.  Of course if you want to visualize it, it’s already on Youtube. Reportedly this is a clip showing an X-bow equipped vessel going 13 knots, overtaking and passing a similar type of vessel equipped with a conventional bow going 8 knots in what appear to be moderately heavy seas.
