  1. I am running a Balmar duo charge for the 2 sets of batteries charged from the original engine alternator (a grunty Leece Neville takes care of the house bank ) https://balmar.net/products/digital-duo-charge/ the alternator's output goes straight to the battery for the electric halyard/anchor winches and centreboard hydraulic pump, which draw some serious current. The duo charge keeps the start battery topped off. Remember under normal circumstances the start battery only requires minimal charging.

  2. You have to understand how an ALT works in a normal situation and how one is controlled by an external reg. As I said above, there are two main ways of controlling. In a non external reg situation, the ALT simply produces a continuous current into a battery. But as the Voltage rises, which is actually quite quickly, the current also quickly (proportionaly) drops. So the actual regulation is caused by the Battery load itself. By using an external reg, the maximum output if the ALT is maintained no matter what the Voltage point of the Battery is. There are two ways of controlling the ALT in

  3. Another little project going on is the adjustable sheet leads for the Genoa. I posted in the tech area on the 3mm dyneema that will be the adjusting line for these. It looks like I'll be able to run a 3:1 purchase through these low friction rings. That will be controlled by a 2:1 purchase set up in normal blocks with cam cleats and 6mm braid. The low friction rings are 50mm diameter, 10mm cross section and weigh 33g on our electronic kitchen scales. Through AliExpress they landed on my doorstep for $6.70 each ( I got 6 of them). They are rated to 22kn, and will take a far higher
