An Interesting Idea
While I only know of this working on cruise ships, because as far as I know they are the only ones to ever have them;Has anyone tried or heard of someone trying to add stability to their boat by installing a number of fins onto their boats hull projecting outward?
Now all I am putting out there is the idea, not the materials or dimensions. Physics dictate that a stream lined object (like a ships hull) is not very stable in a liquid enviornment when wind and/or waves are added. By stable, I am referring to pitch and roll motion of course. If you were to do nothing but add some sort of fins on both sides of the hull, even if those fins remained fixed, it would add substantial stability to cut down on rolling and pitching. This is the exact reason why some of the latest cruise liners have these attached.
Not many people want to pay and arm and a leg to travel an ocean on a rolling boat, even if the weather is foul (Forgive the Hasty Generalization). While ships use a variety of methods from weight, to layout to even gyroscopes on some of the earlier stream liners, I just read of the "Independence of the Seas," the largest most luxurious liner on the planet, having these fins protruding the ships side. The only difference is scale. Also, the fins can move up and down like flaps on an airplanes wing depending on current to add even more stability to the vessel.
***Please for the sake of the idea expand your mind to multi-hulled vessels or even power boats, I understand anything coming off a sailboats hull makes it harder to keel and thus would most likely affect sailing performance***
So what do some of you think? Could this be something coming down the line in the future to more boats of smaller sizes? Do those of you who have extensive sailing, perhaps in higher latitudes where weather and seas are often fiercer, see a place for such an idea or is this sort of add-on only simply unfeasible for use on smaller vessels or sailboats all together?
