Comments on: A long day! Sunday Mar 15,09 http://www.4kconsulting.com/pictoncastle/2009/03/a-long-day-sunday-mar-1509/ A log of my passage on the tall ship Picton Castle Nov. 2008 to May 2009 Wed, 08 Sep 2010 01:12:46 +0000 http://wordpress.org/?v=2.6.2 By: KJ http://www.4kconsulting.com/pictoncastle/2009/03/a-long-day-sunday-mar-1509/#comment-1321 KJ Fri, 20 Mar 2009 15:20:55 +0000 http://www.4kconsulting.com/pictoncastle/2009/03/a-long-day-sunday-mar-1509/#comment-1321 Thanks for the comment John! I should have paced them out better these balks are closer to 35' long and more like 18" thick which would make them more than 2 tons if neutrally buoyant. FWIW According to this cool site: "http://www.allhandsondeck.org/building/lesson4_home.php" a naval cannon in the 19th century weighed around 230 lbs/lb of shot so an 18 pounder weighed two tons. KJ P.S. Susie says 'Hi' and made me promise to mention her occasionally for you :-) Thanks for the comment John!

I think that the 15 March entry regarding the lumber has a glitch. The lumber floated and hence weighed bit less than 64 lbs/cubic foot (density seawater). If these guys were 20' x 18" x 12" they have 30 cubic foot of wood. This means they can't weigh more than 1800 pounds, bit less than one ton. Other than that one nit, nothing else to pick! Keep up the good work, say "Hi!" to Susie for me, best, John R Hi KJ, thanks for your very interesting and well done blog and pictures.
