Good idea.
You want also to add if the weight was taken with or without pad & fins.
I always weight mine with pad and without fins, this is the measure that can be reproduced easily. Be careful to weight the board really dry (a wet pad weight quite more than a dry one)
A good idea would be to have actual weight measured by customers compared to the manufacturer weight.
Here is my contribution:
Some manufacturers that publish their weights are:
Gong: 2010 sandwich PVC line:
http://www.gongsup.com/-All-SUP-Range-.htmlI found their weight are accurate, boards are in fact often lighter than specified. For instance my electric 9'11" weighted 9kg, Nanogene 7'7" 8kg ("heavy" as straps inserts add more than 1kg apparently to total weight, but not to swing weight)
Gong 2011 bamboo "sandwich" (thin sandwich with wood stringer):
www.gongsup.com/-GONG-2011-SUP-Bamby-.html I do not own one, but reports from people having them seem to indicate that the indicated weights are correct
Drops:
www.gongsup.com/-Drops-Moulded-SUP-.html PVC Sandwich Seems accurate: my Vulcan weighted 8.9kg (w/o fins like all my measuraments)
My 7'10" weights 7.3kg (specs in
www.gongsup.com/forum/viewtopic.php?t=1825 ). Note that they all have a mastfoot that contribute ~0.7kg to total weight, but not to swing weight.
Nah Skwell:
nahskwell.blogspot.com/ the weights seem accurate: my 9'6" weighted 10kg, and reports from other users seem to indicate they are never heavier than the listed weight.
I have the 2010 model of the Gerry Lopez 8'10 full carbon by Riviera Paddlesup
www.rivierapaddlesurf.com/collections/all/products/gerry-lopez-810-carbon-stand-up-paddle-board (a bit wider at nose and tail than the 2011 model). It weighted 7.6kg without pad nor fins, 8.2kg with OAM pad without fins
