After getting the frame to location on a Spring tide, it was time to get it in place during a Neap.
At this point I decided to change the shape of the lower part of the frame the boat sits on to the shape of the boat to make it more secure.
This picture was take some time later on the next Spring tide. However in Winter a storm at the same tide height will likely be a bit higher due to low air pressure, so time will tell if it works out..
