PROPE
properties-of-lead-acid-batteries-2
This is a 3 part series demonstrating the properties of lead acid batteries. In this video the properties of a battery while discharging are shown. The graphs show that battery state of charge (SoC)is in directly related in a near linear fashion to voltage. A rough calculation is shown as 0.022v per 1% SoC.
It is important to prevent deep discharges of lead acid batteries since the service life can be significantly shortened if discharged below 50% SoC. For normal usage with long service life it is good to assume that the usable capacity is half that of the battery's rating and that the battery is "dead" when it's no load/no charge voltage is ~11.6v. This roughly equates to 50% discharged. If the only display of battery SoC is no load voltage then I find is easier to think of the battery as full at 12.7 and empty at 11.6v. This mindset prevents me from inadvertently discharging past 50%. I roughly consider that ~0.1v = ~10% of usable capacity.

This video was primarily created to show and discuss the operation of the zipper control line on a my sail pack. Hopefully this answers some questions for my buddy Edd who has the same make and model boat and is looking to have a sail pack made and fitted for his boat.

In my previous video I showed how I was manually tricking the PoE switch with a resistor. in this video I demonstrate my completed dongle that inserts a resistor across the 12v power. It turns out that a 1k ohm resistor is sufficient.

Getting the intake manifold off has a few nuances which can make it a tricky job. If you decide to do this hopefully this video will help you along the way. I got pretty good at it and was able to get it off and then back on in about 4 hours.

ARID
arid-bilge-dry-bilge-alternative
This is a mock up and trial version of a Arid bilge/Dry bilge alternative. I got the idea from an article on a Catalina forum. I really like the Arid bilge system with its 8 different channels of suction. The price is just prohibitive for me and my scale of operation. The Dry Bilge System appears to be a great alternative since it is about 1/3 of the cost of the Arid Bilge. It is still a considerable expense for a relatively simple product. The real concern for me is the repair and replacement costs of costly products. With simple and inexpensive home built solutions the repair and replacement costs are easier to account for.

KEEL
keel-bolt-torque
Quick down and dirty demo on how I torqued my keel bolts.
I used the torque values from the link below as a guide. 316 SS lubricated.

https://www.boltdepot.com/fastener-information/nuts-washers/us-nut-dimensions.aspx
C&C 37+ Keel bolts (fwd to aft):
Nut stud torque 3:1 multiplier
#1 - 1-1/2 1 255 = 85 x 3
#2 - 2-3/16 1-1/2 615 = 205 x 3
#3 - 2-3/16 1-1/2 615 = 205 x 3
#4 - 2-3/16 1-1/2 615 = 205 x 3
#5 - 1 7/8 1-1/4 465 = 155 x 3
#6 - 2-3/16 1-1/2 615 = 205 x 3
#7 - 1-1/2 1 255 = 85 x 3
#8 - 3/4 1/2 38
