The very first time inflate the brand new boat without the floor; then deflate, but not to half the volume, but more: almost flat. This is the most important point.
Some people put soap in the stringers: but I do not recommend that as you will not get ride of the soap so easily.
Some people use rubber hammer to fit the stringers.
Always take care of the position of the boards.
Also place oars down the boat before fitting the stringers.
