Crossing English Bay

Passing RIver Rebel tug underway .014 CPA rough seas English Bay. We realize at around 26:00 that there is a navigational hazard and start making decisions on how to approach it. Very helpful to have the data to make the decisions. Going around the booms would have driven us way off course and with a track back up over the shoals before the North Arm entrance.See More

Renogy AGM batteries

I  have purchased several Renogy products ( solar panels MPPT  charge controller etc) and have  been  very pleased with them. I  noticed that they have a reasonably priced AGM 160 amp battery that I am considering as a back up for my 200 amp system. I am  curious as to what folks think of these specifications and whether anyone has experience with their batteries. I  currently have 4 Trojan AGM batteries to  make 48 volts, so having another bank of  4 160's would greatly extend my range:…See More

Comparing Minn Kota and Motor Guide Trolling Motors

One of my two Motor Guide 36 volt trolling motors on my 26' dory started overheating after 3 years of use so I decided to replace it with the new Minn Kota 112 lb thrust Riptide (i.e. Marine) motor.  On paper it looks more powerful than the Motor Guide (50 amps instead of 30 amps at 36 volts - 1800 watts vs. 1080 watts). Yesterday I had the opportunity to compare both motors and here are my data. 1. Conclusion #1: The Minn Kota with the two bladed prop as it comes out of the box is not as…See More
