I lifted the front of the port hull with my son 120 lbs on the starboard hull to see if there is some loose there is only a little flex. How much flex is accetable?
a little is expected, if it's very obvious (you can see/feel it while sailing) you have lose beam bolts or something needs attention
How do I post pic's without a web site?
you need to upload them to somewhere first. you can open a flicker account, or something similar (picasa, beachcats, etc).. then you can link to them
