I have a question regarding bottom shape on a boat designed for cruIsing around 5 knots or so. I have become quite taken with the look of the slipper launches on the Thames River and so has my wife. I am moving soon to a community that has its own several hundred acre lake and a boat like a slipper will allow us to take advantage of the calm waters of that lake and the local waterways. I would like to try my hand at designing the boat myself to see if I can do it. If not then no biggie and I will move on to something else. But the exercise of trying is where the fun lies. I know I can get slipper plans from Selway-Fisher but this is more about the process than anything.
So with that said I am moving to design the hull. Since this is a slow leisurely boat (5-7 knots) I am looking to make the hull with a flat bottom much like many Atkins designed boats. The stem will have a slight rake to it but very little. While I was browsing this years Small Boats issue the ocean pointer caught my eye. One thing that I noticed was that the bottom of the boat was flat from stem to stern the whole way. I made me wonder from a design standpoint would this work for a slipper launch, especially considering the slow operating speeds. Also, with a boat like a slipper and a flat bottom, what sort of draft would I be looking at? My biggest concern is how it sits in the water.
Any ideas on this are appreciated. I am attaching a quick image file showing the overall look of the boat. If this idea won't work that that is fine. It is just a learning process. Thanks for any help.
