Yes, ramp launching will be much easier with a swing keel, however you do give up something vs a fixed keel, esp in the area you are planning to use it.
There are some fixed keel boats with shoal draft such as a Shark24 (3 ft) and they're light enough to trailer without a serious truck, but ramp launching becomes an issue if the ramp is not steep. Extending trailer tongues help here, and also many BC communities have public wharves with small 5 ton cranes - in many cases (sometimes for a modest fee - btw not all ramps are free either) you can use that crane to lift a boat off the trailer and drop it in the water. Some are manually operated and are usually free (it can be a workout) but nowadays more and more of them have been motorized.
