You Cannot Use Stainless Steel on a Steel Ship, Or Can You?

EP30 - Rust, Corrosion, Oxidation. How to keep it far away from your ship? We're replacing our rusty anchor hawse pipes for stainless steel ones, the capstan on the aft deck gets some well deserved attention and we're removing our identification numbers from the hull.
Schoener Tijgerhaai (Tigershark) started life in 1944 as a canadian built tugboat and she has been in my family for almost 50 years. Together with my dad, I am rebuilding this beautiful sailing ship, to get her ready for new adventures!

Ep 30 - You Cannot Use Stainless Steel on a Steel Ship, Or Can You?

[@jamestjomsland948]

Yo Mates!! Great to see Dad and Son working together on such a glorious Ship! jimmy

[@tigersharkboatworks]

Thanks Jimmy!

[@SavingMaverick55]

Its a steel boat. Corrosion is always going to be a thing. 316 marine stainless is about 70% iron anyway, so I would really doubt that combining it and regular steel above the waterline would present any issues at all. Great work. She looks great with the anchors in place!

[@tigersharkboatworks]

Ah yess, that's a good point, thanks!

[@benmac940]

Yeah it's not that uncommon, never seen or heard of it causing issues.

[@clivestainlesssteelwomble7665]

​@@tigersharkboatworks It's best if it's solidly inertly welded.

[@torrespearls381]

Most enjoyable watching the progress with the two of you. Cheers.

[@tigersharkboatworks]

Thanks! Cheers :)

[@peterrobierto7435]

It’l be a lovely ship when its done. Your raft creases me up 🤣

[@tigersharkboatworks]

Thannks! People passing by also find it a funny looking garden 🙃

[@AlanKaufer]

Seeing the anchors in place gives your ship a much more completed look. A small detail that makes a big visual difference.

[@georgemarris]

Gijs ? Good to use stainless wherever you want , never worry about bi metallic corrosion , that’s only underwater, and we don’t worry about it anyway .. cheers from Tasmania

[@tigersharkboatworks]

Lets try to keep all that stuff above water then :)

[@romandybala]

If the original oxy bottle tube lasted 50 yrs another one would see that young bloke out. Maltese gold is what we call stainless in Victoria.

[@tigersharkboatworks]

Yeah, but it's always painting orange stripes on the hull :)

[@MartinErlandson]

Orange stripes on the hull, rust!?!?! No no thats the morning coffy I spilled. 🙂 Stainless (1.4404, 316L, SS2348) and steel/iron welds very well together indeed. Cover the transition of metals with paint and it will last "forever". Nice seat on the aft winch - now the crew wants a bigger sofa at the aft! :-) Great job Dad & Son!

[@tigersharkboatworks]

Hahahah people have to stop drinking so much coffee, or learn to keep their cup straight. The crew can have whatever they want, except money, we don't have money :)

[@sheepdog1102]

Good job 👍

You and your dad are always repairing and modifying even the smallest things , 👍🏻👍🏻. When can you show us a boat tour below ! Have you done any major work below ?

[@tigersharkboatworks]

We're using the opportunity to tackle it all! Good idea to do an updated tour below. We are currently busy in the forward cabin area and in the engineroom, but the saloon is still a big mess, waiting for poor weather :)

[@paulroberts237]

Great to see you working with dad. The boat is covered in white paint and red anti rust paint. Can I ask what the final colour plan is and will you dry dock to do the underside/ bottom/ anti foul paint? Great videos, keep them coming. Great to see the boat being rebuilt.

[@tigersharkboatworks]

Thanks! The final colour plan will be the same, white hull, light grey deck, and red antifouling. The main reason is that white really helps keep the inside of the ship cool in warmer areas. It also makes it very easy for us to spot rust :). In drydock, we'll get a clean hull and fresh layer of anti fouling, apart from hull thickness survey and some underwater thru hulls etc. Thank you!

[@ronkluwe4875]

More great work and nice solutions to the issues that come up. What I am going to suggest is more an industrial application, but have you looked into an impressed current cathodic protection system for your anchor tubes? Under way the tubes are always going to be water soaked and dropping and raising the anchors is going to abrade away the protective paint. The cathodic protection system does not have to be very fancy and should be able to be fabricated for minimal cost.

[@tigersharkboatworks]

Phoo, an iccp does sound fancy. We're trying to keep things as simple as possible. The new stainless pipes should do the trick, right?

[@ronkluwe4875]

@@tigersharkboatworks Actually it could be as simple as a 6 volt battery with a couple of wires. The SS is going to be okay, it is the connection point to the steel where the corrosion is likely to occur.

[@tigersharkboatworks]

We're gonna monitor how it holds up. If it doesn't work out like this, we can always install a simple iccp like that in the future. Thanks!

[@craigscoullar564]

Excellent content love it nz

[@davidantill6949]

Thank you. Another very enjoyable video 👍🏻 Do you use your raft to grow tomatoes to avoid scurvy?

[@tigersharkboatworks]

We call that nature inclusive building, but we might just drag it along on our voyages, because of the scurvy

[@TheCavemancam]

Big respect to you and your dad ! Tough on the wallet now, are you planning to make some money by joining the brown fleet on the Waddenzee/noordzee/IJsselmeer ? Looking ahead, when do you think you can hoist the sails again, 2025 ? Also i suspect your last name is Klinkhamer, and that ship is an adult version of the kameleon. Best regards from the Philippines

[@tigersharkboatworks]

Thank you! We probably won't join the Brown Fleet. The ship is a bit deep for playing around the Waddensea and IJsselmeer, so we're always bound to the fairways. North Sea could be an option, but we're not really sure yet where we're going once we're finished :) It would be nice to have her ready in 2025, but no pressure. I wouldn't really call ours a speedboat, but she's also steel and bulky, so yeah, I guess :)

[@martineyer5336]

Nice so much weight in the boat. Everything is just so heavy duty. 😂

[@MonkPetite]

Ever thought of a 2K primer?

[@tigersharkboatworks]

Have thought of it, don't like it. Mixing is messy, grabbing a can of 1 comp is much quicker, and we have very good experiences with red oxide :)

[@davidwarnes5158]

Do you require the engine or generator to run while under sail ?

[@tigersharkboatworks]

The solar panels deliver more than enough energy to sail and live without running an engine :)

[@davidwarnes5158]

@tigersharkboatworks is that with all system running , you don't have much solar , fridge, auto pilot for the boat must be heavy usage. ?

[@tigersharkboatworks]

We have 2500Wp solar, which is quite substantial. The modern fridges are very economical, al the new electronics use peanuts, and the steering pump uses 300 watts. All together, we have energy to spare in summertime. In wintertime, we have to run a generator for an hour a day to top up the batteries :)

[@renexxx2017]

Dat zijn beste ankers😊

[@tigersharkboatworks]

Ze zijn wat aan de grote kant, 260 en 200kg :)

[@apivovarov2]

why you use stick welding? MIG welding is known for its versatility, making it suitable for various materials, including steel, aluminum, and stainless steel.

[@tigersharkboatworks]

We prefer stickwelding because all we need for that is electricity and rods, so wherever we are in the world, no need to go look for argon or CO2 bottles or whatever. We do have a MIG welder, which we only use for alu :)

[@davidwarnes5158]

Thats standing still at a dock . I have worked on yachts that size . Solar at 100% capacity will be close but how much when sailing will be in the shade . And cloudy days .and night hours . No sun . Can you all hand steer . Or does steering require power .

[@tigersharkboatworks]

We are gonna have to find all that out. I'll be able to tell you in a year or two :)

[@davidwarnes5158]

@@tigersharkboatworks that you will, thats a heavy boat to go around on burning diesel , what does your main engine burn per hour . Ltrs 10 ? Battery bank has to be big , but if leadacid , evan bigger as can only use 60% of battery life for long life . Generators are the most unreliable thing on a boat , you go on large boats so can see this conversation is valid . Keep the great work up, respect

[@tigersharkboatworks]

10 litres an hour on average indeed. They are, and the most maintenance intensive. That's why we want to run them as little as possible :)

[@davidwarnes5158]

@tigersharkboatworks batteries storage of power and producing power , your biggest problem for the future , I have worked on sailing yachts that require more than that , batteries first to upgrade , lead cannot take the amount you need to put in quickly , miss out a generator. Very large output altinators awsome way to go , but not when burning 10 litres an hour . Can you get a small diesel engine , run on about 2 litres , and only used to create power not propulsion. With large output altinators , you have the room, save 1000s € in fuel. What do you think, ?

[@tigersharkboatworks]

Sounds like a very good plan

[@05stones]

If I understand correctly, you never made any trial on the boat in navigation ? You don’t know his behaviour in the waves ?

[@tigersharkboatworks]

I don't know where you understand that from, but a quick overview of the history: Dad and Granpa got the boat in 1975 as a tugboat, spend 14 years converting it into a sailing ship and circumnavigated the world in 4 years. Afterwards, apart from a short holiday every few years, she's been sitting around, getting out of date. So now, 30 years later, we're getting her ready to sail again. Concluding, yes, we know how she behaves in waves and how she navigates :)

[@05stones]

@@tigersharkboatworks many thanks for the quick response. It was just a question because I’didn’t move it since a follow you. Looking forward the navigation. 👏👏👏

[@arendbijlsma6459]

Hoi Gijs, heb jij geen wartel tussen het anker en de ketting zitten. Dat hoort normaal wel.

[@tigersharkboatworks]

In mijn ervaring is het voor zulke (zware) ankers niet gebruikelijk om een wartel te hebben. Hier zat er wel een op (gegalvaniseerd), maar die zat natuurlijk vastgeroest. Een rvs wartel helpt ook weinig, want het gewicht van het anker geeft zoveel weerstand dat de wartel niet meer wil wartelen. Er bestaan hele luxe rvs wartels met een taatslager, maar dat is meer iets voor de superjachten dan voor de oude schepen. Dus die vastgeroeste wartel hebben we er maar tussenuit gelaten :)

[@arendbijlsma6459]

@@tigersharkboatworks toen ik in 2019 voor de herkeuring van het CBB ging zat BB wartel zo vast als een huis en SB wartel was gangbaar. Men gebruikte in het verleden altijd SB anker. Van de inspecteur moest BB wartel gangbaar gemaakt worden en van SB anker de pen worden vervangen want deze was te los. Ook moest het gewicht op de schacht gelast worden. Mijn ankers zijn zo'n 250 kg per stuk. Ook geen kleintjes dus. Op de grote zeevaart schepen zit er volgens mij ook wartels tussen maar moet zeggen die dingen zie ik niet zo vaak meer. Sta met ten anker gaan niet meer voorop maar achterop en geef eigenlijk alleen maar de order lekko. Groet, Arend

[@tigersharkboatworks]

Goed dat je het zegt, ik kan op het internet niet vinden of ze voor het CBB verplicht zijn, maar daar kon je wel eens gelijk in hebben. We gaan ze gangbaar maken en gooien ze aan boord. Als de inspecteur er commentaar op heeft kunnen ze er in het dok zo tussen :) Bedankt!

Your anchor shackle looks to be barely half the diameter of you chain. It should be at least the same diameter as the chain otherwise it can compromise your whole anchoring system.

Ah, that must be an optical illusion, but you got me here with the caliper. measuring 19mm on the chain and 20mm on the shackle :)
