Soda blast or just scrape and paint

[BRIELLY]

I'm hoping some of you can help me with this decision as Ive received numerous opinions. The boat is a 78 v20 with what looks like numerous coats of bottom paint the has come off in some areas, and is flaking in many other spots. Some of it actually appears to be on pretty good. One yard recomended geting it soda blasted and gave me the number of someone they trust. After speaking with the soda blaster he suggested not soda blasting now because the hull would most likely have high moisture content and new paint would not adhere well to it. He said wait until the fall and let it dry out over the winter. What do you guys think? Is this good advice? I wasn't really looking forward to paying for the soda blasting at the moment anyway. Although scraping/sanding while on the trailer doesn't seem like much fun either.
