I’ve had Progressive for almost three years. I just finished a claim with them that totaled around $6500. Handled quickly, fairly, and pretty much hassle free. I’ve got no complaints at all. While moving from TX to FL last year along the ICW I also used the sign and glide more times than I’d like to admit. Calls were handled professionally and quickly each time (ok, it was three times during the trip). They call whichever tow service is closest to your location, so I had both SeaTow and TowBoatUS. There’s an app, or a phone number depending on which you prefer to use. There’s a provision in the coverage that allows reimbursement if you call for assistance on vhf versus calling sign & glide, but I haven’t used it so can’t say how that works.
