Is there any hope of making this trailer work with this boat? Its a 1999 4winns trailer that from what im told had a 21' 99 model boat on it. From what i understand the older boats such as my 85 santara 210 had deeper hulls.
Good tie down points need to be added also. I don't see any. Some on the stern to keep it from riding forward and keep it down. I would add a strap over the bow to keep the bow down and in place if you suddenly decellerate.
What are the tires and axles rated for? What is the boat weight with fuel and goodies? If they don't match you could easily trade that trailer off for one that will suit your needs.
I would move that jack/wheel closer to the toung/front of the trailer.
A lot of strees on that thing right now.
Its like a lever, try lifting the trailer (by hand) where that wheel is now, you probably cant do it.
now go to the front of the trailer and try. probably a lot easier
