|Not uncommon in my life.|
While prepping gear and boats for a group to appear, I would watch the boat ramp. Boat ramps are designed for power boats. the idea is you have a boat on a trailer which you back into the water. You then either get in your boat and take it to a dock, or just line it to a dock. Then drive your trailer to a parking space. Total time on the ramp, 3 minutes or less.
I would also see kayakers use the boat ramp. It seems obvious. A kayak is a boat. It is called a boat ramp. I should put my kayak in the water utilizing the boat ramp. The problem is, we are slow. We carry our boat from our roof to the water line. Then go back to the car to get paddle, pfd, and whatever else we need. Then make another trip to park the car. Then we can finally get on the water once we put on paddle, and secure everything else. This never takes less than 10 minutes. If the person involved is a kayak fisherman it takes even longer. (I'm not knocking kayak fisherman, but you people have a lot of gear!)
What I suggest is this, find an area adjacent to the boat ramp with a beach like appearance, and stage your boat and gear there. It is courtesy not to block the ramp for an extended period of time, and it is also better for your boat, as the ramps are almost always concrete. Because they are concrete they are also usually slippery, and more than once I have slipped and fallen.
While the above reasons are valid, they aren't the best reason. The best reason is courtesy. We all want to get on the water and have a nice day, and if you can't get on the water because some kayaker is taking forever on the ramp, you are going to be in a foul mood. I don't want anyone on the water in a foul mood.
Another option is to do a dock launch. I don't really like them, but a lot of people do them all the time. It is something to think about, and there are times when you don't have an option, so it is a good skill to have.
I have a third option that is my favorite. I used it extensively when my boat lived on Long Island, New York. I kept in my truck a copy of the Gazetteer for New York. I spent a fair amount of time examining the coast line of Long Island looking for places where road, ran to, or along the water. I would then drive that road looking for an easy put in. It was crazy fun to explore dozens of small dirt roads and find a secret spot to put in. I would then highlite the put in so I had a quick reference for another time. Today we can do the same thing with Google earth or Google Maps. Boy do I miss that book. It was a great resource, and as much as I love digital maps, there is something about a paper map.
