Is it considered copyright infringement to change all the dimensions on the
plans in order to enlarge the boat for personal use?

Only if you publish the revised plan as your own. You can do anything
you want to for personal use only...copyright does not carry an
obligation to "follow the directions exactly." If it did, just about
every cook in the world would be guilty of copyright infringement...'cuz
I don't know of anyone who's capable of doing more in the kitchen than
making toast who hasn't "improved" or substituted ingredients in recipes
in copyrighted cookbooks...not always successfully, though.

Which raises a point: are you sure the structure called for in the plan
will support a larger hull?
