I don't get in the water.  I don't really have an easy way to do it. 
 
I try to find a little help and drag it up onto the dock.  I usually attach a couple of lines to it to pull with.  Sometimes I can pull it with a metal rake.  It is not pretty and really involves just muscling it up. 
 
I find that if I raise it all the way up first a lot of water drains out of the channels in it and it gets lighter.
