Topic: Training aid idea Posted: 25 Jan 20 at 4:17pm |
This not intended as something to be a commercial product just a bit of fun. It stared with thinking about speed through tacks and wouldn’t it be good if to knew that you were slowing down, by how much and then use this information to improve your technique. I figure that a system that would work would be an audio system, initially thinking that beeps would get closer together as you sped up and further apart as you slow down. This would only really work if it was comparing relative speed over the past den seconds say. This would ensure it works at two knots and twenty knots. I have started messing about with Arduino programming and it seams relatively easy. I’m thinking supper simple. You have a piece of rope tie it to the rudder stock and throw it overboard, near the boat end is a small container with the electronics and the speaker, the outboard end has a spinner, think Walker log. I appreciate there are all sorts of fancy pucks with logging and readout but this is just about in the moment understanding what is happening to your speed without looking at a display Any thoughts would be appreciated, again nothing commercial just a bit of fun. |

Yes I'd just like an audio feedback on the speed at all times. Walker log sounds interesting. Or a paddle wheel type sensor taking the place of a Laser bailer or shute type bailer. |

I have an onboard system already. On a bad tack, I will get " the stare" from my crew. The very bad ones get a head shake as well.

When you start hearing voices it's time to really worry!
Just a thought, with the size of the Pike in Blithfield ( up to 44lb) , towing a small fish sized canister behind the boat could result in exciting moments |

I would have thaught that a GPS module would be cheaper than a paddle and generator it would also reduce waterproofing issues.

I think you’d learn more from a GoPro mounted in your boat filming your movement through a manoeuvre. The problem with speed reading is you’d have to either watch a speedo, therefore stopping you concentrate on actually what makes a good manoeuvre or pulling through lots of speed traces on computer then trying to work out what you did in each one.

That was why I thought auto would be good, a simple sound system that changed to indicate acceleration and deceleration. That way it is completely independent of wind speed.
