Wet and windy day 21st Feb 2025

 Well all though it as forecast a gale and wet I had to go into town anyway so I went to boat as well  

My port window leaks around the rubber seal 

So I put tempory some buttle tape 

Got 2 loose bolts tightened 

 

Got the front nav light to show 

Got both speed log and depth to illuminate 

Starboard nav light lit

Port nav light lit 

Added in a long led light in cabin. 3m tape to side under window.  Draws 0.6amp ??? A lot 

My victron charge controller has Bluetooth so I could see the draw  

To calculate the power (in watts) of this supply, you would use the formula:

• Power (W) = Voltage (V) x Current (A)
• Power (W) = 12V x 0.6A = 7.2 watts 

To calculate watt hours from 12v at 0.6 amps, you need to multiply the voltage (12v) by the amperage (0.6 amps), resulting in 7.2 watt hours. 

A "12v 7aMP" battery is equal to 84 watt hours. 

Explanation:

• To calculate watt hours (Wh), you multiply the voltage (V) by the amp hours (Ah). 
• In this case, 12 volts (V) x 7 amp hours (Ah) = 84 watt hours (Wh). 

Formula: Wh = V x Ah 

so 11hrs of led light on a fully charged batt

Cleaned up a bit , the cabin floor was wet again

I now know where from the cockpit drain hole pipework in rear qtr berth so I stuck some butyle tape in both sides for now and see.    It was at least a bucket of water 

The rear nav light couldn’t get to show so maybe bulb or holder 

Had a brew love my trangia it’s so easy 

Blowing a gale in the harbour but I was happy bumbling 

So at least I’m more aware than the other day 

So that’s good 

I have so many battery’s onboard for this and that I may just put my 100amph one on instead it’s so light 

I got the controller for it so no problem 

Having all the kit at hand is so important. Especially when wiring up.  I found a crimp on my garmin 4cv rusty so quickly re did that 

Back tomorrow to bumble again
