my method for marking chain length utilizes the EIA standard resistor color code whereby the following colors denote a specific number.
Most engineering types already know the EIA resistor color code and it's practical info for the ship's engineer
as well. I used to spray paint
the colors on my chain, but found the paint was only temporary and expensive. I now use colored 6" plactic tywraps that I purchased on ebay. I apply 6 tywraps every other chain link, so I cover about 1 foot of chain. I have an electric windlass
and 5/16" chain. The tywraps move through the wildcat without any notice and I haven't lost
1 tywrap that I am aware of. I have 200 feet of chain and mark it at 5', 50', 60' and 20' intervals thereafter. IE;
1' through 5', flourescent yellow to warn of anchor's approach
195 through 200, florescent yellow to warn of nylon rode
Although I haven't tried it, I would expect the tywraps would work equally as well on 3 strand nylon rode
. Brait and braided nylon should also work if the smaller 3" long tywraps were substituted. In practice prior to anchoring
, I determine the total depth
, multiply by 5, determine the correct color and inform the deck
crew to release rode until they reach the tywrap color ordered. Very uncomplicated for the deck
crew. Until the color code becomes memorized, a crib sheet could be kept in the cockpit
cutout to make the correct color determination.
One man's opinion.
