Sailboat, sailing and replacing zincs Replacing the Zincs on our Volvo folding Propellers - in the water. TECH Tip In this video we focus on some of the technical and maintenance jobs we get up to on Double Trouble. If you like the video let us know with a thumbs up! Sacrificial zincs are attached to our sail drive legs and propellers and are used to protect metal structures from corroding. They work by oxidizing more quickly than the metal they are protecting, and are consumed before the other metal reacts with the electrolytes. This means our expensive aluminium sail drives and and brass propellers will be less susceptible to galvanic corrosion. We normally do this on the hardstand, but with no option for hauling DT out of the water, we put on a snorkel and jump in to replace the anodes. ------------------------------------------------------------------------------------------------------ ☕️ Want to Buy us a Coffee?

We are Jo and Rob and we are here to share our sailing adventures with you. In 2016, inspired by the likes of ‘Delos’, ‘Sailing La Vagabonde’ and ‘Gone with The Wynns’, we sold up everything we owned and bought our 40ft, Fountaine Pajot ‘Lipari 41 Evo’ sailing catamaran ‘Double Trouble’. We had no sailing experience whatsoever, so the past few years have been a huge learning curve. We thought it might be fun to document our travels for anyone thinking of following a similar lifestyle. So far we have visited 7 different countries and sailed over 13,000 nautical miles. We have had many unique experiences that would not have been possible in our prior life and we don’t regret a second. We're both super keen on protecting our precious environment, so amongst other things, we both follow a plant based diet. You wont find any fishing footage on this channel!

today we are changing the zinc's on our

sail dried legs

hi there we've decided to put together

some short technical videos documenting

some of the repairs and maintenance that

we get up to on double trouble this

won't be a regular thing we'll just

publish them when we think there is

something relevant to show so if there's

any particular topics that you would

like to see please let us know in the

comments below

[Music]

we have Volvo three-bladed folding props

and we have two sets of zinc's first are

on the actual sale drive leg

I've just had a quick look at them

they're fine they seem to last probably

a couple of years for some reason we do

have some more saints that are on our

props themselves and they go around in a

collar so I've got some here and these

haven't lasted as long they're not quite

as big so we're going to be looking at

changing them out today these go around

the prop shaft we're going to change

them in the water so we haven't done

this before on our boat we normally do

it when we call out and we aren't

planning on getting the boat out of the

water in the short term one thing that

we use is locked tight so we typically

use this on dry land the nice thing

about that is you're not in the water

and the Loctite has a chance to stick to

the screw and then when you screw it in

acts like a glue so the screw doesn't

fall out and then you don't lose any you

think anodes we've only got the two four

three block tight which is not

technically waterproof but apparently

there is a little bit of a trick you can

put this on the screw thread leave it to

dry for an hour it'll go stachy and

stick and then you can use it in the

water alternatively you could use two

four eight Loctite which we haven't got

access to and there's a few other

products as well if you check the

comments and the link below is some of

the things that we're going to be using

to do an in water zinc change we

obviously need the zinc's we're using

Volvo sinks which are quite pricey there

are a number of other aftermarket parts

you can get MARTA are a good option they

have sink starting at around fifteen

dollars and the smaller ones they're

probably in the region of about thirty

so some savings there again the links

are below if you want to check those out

we're gonna remove the existing zinc's

and then we just need to clean up the

area that they're going to be installed

in so to do that we have some green

scrubby stuff that will allow us to just

get rid of any growth and make sure that

these sakes have a nice clean contact

onto the brass of the

some wet and dry sandpaper just some

fine grade stuff and I can I can use

that to make sure everything is super

clean I've also got a waterproof

screwdriver that I can use if I've got

any tough bits that I need to chip out

then I can use that in conjunction with

this that'll get it all nice and clean

there are some metric allen keys see

what size you need and then take that

down into the water with you and and

screw it in because we're going to be in

the water you obviously need some seeing

goggles so we've got a nice underwater

mask here in my case I'm going to be

using a snorkel but if if we need to

then we would also use our dive gear and

just roll in with those I'm going to get

one of our buckets with a bit of string

over the top and put it underneath the

drive and then if we do knock anything

or anything falls then it will fall into

the bucket and it won't fall to the

bottom of the sea with the lock tight

give it a good mix and then just apply

it gently to the thread and then you

just leave it for an hour to soak in and

dry

so shock horror I've just read the

manual and on the zinc's they also

recommend you get some oxidization on

this as it's in the air and they

recommend that you give it a good clean

either with a very rough Buffett or I'm

actually just going to use some

sandpaper and and just clean all this up

so that it's it's fresh the surprising

thing for me I tried it with the snorkel

it's it's fine but there's a surprising

amount of current that you're always

cooking against so just gonna be easy

just throw this on

[Music]

[Applause]

here's the old zinc's and as you can see

they look a little bit different to the

new ones so after a year definitely time

to change them out and yeah the new ones

will continue to do their job thank you
