Thanks for reaching out to us. I'm just starting to think about the idea of playing around with a scaled hull which I can add different types of stabilization ideas. These are very uncharted waters for me and I'm not looking to prove anything to anyone but rather confirm in my own mind a few "what ifs" on a gross scale. We are not sailors but last year when we went out a 45 Sailboat (first time) I was very impressed with the reduced rolling motion even without sails up. I attributed this to the long keel and low profile salon. It was like the wind just went over the top of the boat and felt very different from our previous tall Nordhavn's.
Regarding size I'm thinking around 1/20th scale (40' hull equals 2' model). I'm not sure that scale will even replicate how the hull shape would really perform but if it is close I'm happy.
I'm looking for a traditional mono-hull sail boat style hull with a removable keel. From there I would build different style stabilizers and attach to the hull for testing.
For testing we are looking at very primitive (in the pool) style testing. We would do this on a very hot day so if the hull sinks at least I can enjoy the water as swim down nine feet to retrieve it. Fortunately our pool has a beach entry, is 50' long and has various waterfalls so we can create all types of conditions from dead calm to significant size beam seas. (ha ha)
I thought about just purchasing a plastic model sailboat then realized I need a more precise weight distributed hull to help with the testing? I'm not even sure what type of material I would use. Any thoughts? Thanks
