I am reviving this 2-year-old thread, because I have an idea for something. Probably already exists, because that usually turns out to be the case, but I haven't heard of it.
How about a digital "level" to install on beach cats (or big multihulls, too)? An attitude detector.
Everyone who races beach cats knows that weight distribution is very important to speed. And the reason weight distribution is important is that you have to try to maintain a certain fore-and-aft attitude of the boat in the water for maximum speed, as well as a certain optimal lateral attitude (amount of heel).
Of course, I don't believe in looking at a lot of instruments when you are actually racing, but it could be a valuable training tool so you can find out what angles and attitudes work best for your particular boat in various wind conditions.
So what we need is a digital read-out "level" that will show the boat's fore-and-aft and sideways attitudes in the water. If these digital attitude read-outs can be correlated with GPS speed readings, you have one more tool to figure out exactly how to balance the boat weightdistributionwise for maximum speed.
I know that there is a safety device for big multihulls that senses the amount of heel, and if it gets beyond a certain point, sheets are automatically released. But what I am talking about is a lot more sophisticated.
What do you think?
For the benefit of novice racers, there could be an alarm that goes off when they are sitting on the back of the boat and dragging the sterns in light air and they need to move forward. Or when the bows are digging in too much in heavy air and they need to move back.
It could drive sailors crazy! It could be called BAD (Boat Attitude Detector).
P.S. If YOU have an invention idea, please look at my original post on this thread and read through the whole thread, because maybe somebody has already thought of it, or something similar, to which you can add more ideas.
