You need a hub or a spindle or both???
I would assume you need a spindle before anything:

Page 4 has part numbers. What year trailer you got? My 99 had a freak size that Boatmate only ran for a year or two that had like a 2.3sumpin inch rear seal vs industry standard 2.5sumpin inch. First time I replaced the seals on that trailer I played hell finding that seal anywhere in stock. Jerry at Boatmate told me that's why they changed too the 2.5 a year or two later.
You can call Boatmate with your trailers VIN and they can hook ya up. Otherwise you'll have to take a dial caliper too your hub and spindle and match it with the descriptions on the above link to find parts in C-town.
Putta jack under the bad axle/hub and raise the trailer off the ground, take one of your transom straps and wrap it around that axle just under the trailer frame, lower it and she'll ride fine. I came home from Pickwick once with a the right front wheel gone. No more than the XB03 weighs it should work ok.
OOPS I forgot your trailer WAS a single axle wasn't it? Don't know for sure then, but she still SHOULD ride ok. If nothing else you might have to yank the wheel off the otherside of the axle and bringer home on one axle.
Good luck bro,
