Speakers: Professor Emeritus Bruce Johnson facilitating.  Captain Jason Quilter and Captain Jan Miles contributing.

A look at sailing ship stability in extreme wind conditions, with particular attention to Operator Guidance in terms of squall curves, maximum steady heel angle, responding to extreme wind, down flooding, and material condition.

Speaker: Captain Jason Quilter

Jason Quilter is a Captain and Nautical Science Instructor for SEA Education Association.  He has eighteen years of experience in vessel operations among the U. S.sail training industry and recently collaborated  with SEA to create a preliminary set of squall curves for the SSV Corwith Cramer and Robert C. Seamans.

Speaker: Captain Jan Miles, a Captain with Pride of Baltimore II

 

Jan has worked professionally as an officer or master aboard classic yachts & traditional working-sail vessels (tall ships) for the last 40 years. The majority of his career is aboard fore & aft rigged vessels, but also in square rig. Jan’s sailings have taken him across the Atlantic six times, down the length of the South Atlantic once & deep into the Pacific four times, three times via Panama. once from San Francisco (Hawaii three times, one time on the way to East Asia, plus one return from Japan to Seattle). Jan’s coastal experience is extensive and includes multiple transits on all three coasts or North America plus the equivalent of a dozen round trips deep into the Great Lakes along with several transits in the Caribbean Sea. Jan has also sailed more than once around the British and Irish Isles as well has numerous transits in all of the Seas & Channels of Europe west of Genoa, Italy in the Mediterranean and St. Petersburg, Russia in the Baltic. In East Asia his sailing was first south then north between Shanghai, Hong Kong, Taiwan and Korea. Most of the above experiences were since 1981 as master of one or the other of the two PRIDEs. 

 

Since 1989 Jan has been one of two full-time captains with Pride of Baltimore, Inc., co-managing care between taking turns sailing the square-topsail rigged schooner PRIDE OF BALTIMORE II.
