Here is how I removed my Tahiti from the trailer. I needed the trailer to haul another hull home. I am not recommending this method for the faint of heart!!! Was finally able to look at the bottom while it is up, and definately need to flip it this winter. Probably losing a couple of MPH from the crappy repairs someone did before I bought it.
Here's how I lifted it:

I lowered the trailer tongue as low as I could (which raised the stern), attached the stern straps, raised the toungue back up, ran the bow straps, rolled the trailer out, and finally strung the belly strap and corner ties. Coming down will be done in reverse. Hopefully with no loud crash involved!!!!
