90% of the time I launched by myself. Both guiding here in VA and when I fished in FL. there are a few easy ways and I would never let launching alone stop me from a day on the water. Lot of factors to consider. First the time of year, type of boat, the type of ramp, wind, current and docking options. Normal with a concrete ramp and dock, I just unhooked all of the straps but not the bow, then backed in close to the dock leaving the trailer out of the water just enough to hold the boat on the trailer (key is watching the rear of the boat float up), get out of the truck, jump in the boat, lean over from the front deck and unhook the bow, fire it up and reverse off the trailer, tie up to the dock and go park the truck leaving the boat running for its warm up. Some will tie a rope to the trailer (especially if no dock is available)or some use the bowstrap, and back up until the boat floats off, then untying it and pulling it alongside the truck. If you have to beach for any reason you ought to be emailing me for a KeelShield, it will save your hull a lot of damage when/if you have to beach for any reason.
