Armor Plating


Armor plating, also known as sheathing, has been our life for the last two weeks. We started at the waterline Saturday before last and we are blasting through it. We’ve now sheathed almost to the transom. Our goals have been waterline down then from boat stand to boat stand, day by day. This is day one:

The Young Salt and the Tar Queen

Getting the first three planks on took the longest as we had to test fit then permanently tar and screw them in; setting the flow for the rest of the planks down to the chine. Now that I think about it I don’t know if I can call this day one… Days prior to this we had to sort and transport all the good pieces of fir to the boat from their storage place at my parents then plane and mill those boards into 3 inch by 3/4 strips of sheathing planks.

You’re probably asking yourself why…? Why sheathing? What’s the purpose? Is that necessary?

We debated the same questions.

So the purpose: sheathing is essentially double planking an already beefy hull but the true purpose beyond extra strength and basically making the boat bulletproof is it is a sacrificial layer. Meaning worms, icebergs, pilings, partially sunk shipping containers, you name it could attack the sheathing leaving the main planking safe or at least keep us from leaking/sinking until we can repair damage. Most importantly, meaning Garrett’s number one concern, is the protection from worms. We plan to sail to the tropics. Lush beautiful crystal clear blue water but we’re not the only ones that thrive there; teredo worms love it too. Interesting fact about marine worms is that they tend, when eating wood, to stay in one plank zig zagging back and forth up and down. This makes having a sacrificial layer distanced from your structural planking with heaps of tar a wonderful piece of mind that your home will be safe and its integrity held.

And is it necessary: Is building a boat?…

We’ve come this far why not a little further into insanity?


Day two Garrett set a big goal, sheath all the way to the chine before days end. Garrett and I did ok, getting two full runs up by about 5 leaving only 2ish runs left to reach the chine. But we were pooped! Thanks to our amazing neighbor who cranked up the


sea shanty tunes and kicked our butts into gear for a final push. With his help and every minute of daylight

we achieved that goal.


…We really wore Swab out!



The following day was a video making day for me and a trimming day for Garrett.


We’re really happy with how the sheathing is coming. Garrett just hates the sticky… It’s going to be so great when it’s complete and a huge mental ease for Garrett knowing it’s below us. Speaking of below us, so presently it is gravel but she is a boat and one day she’ll float! This project is the last major one before launching day. After the sheathing is finished we’ll be ready to slap some bottom paint on her and wheel her to the ramp. A few odds and ends remain but no more cabin modifications or holes–I probably shouldn’t say that out loud—good thing I just wrote it 😉

  1. Wow! Sounds like great insurance against worms and possible impact damage, and another good decision! No sense in rushing the project at this point and possibly regretting it later. So happy you’re able to spend more time on the boat, Ruth! And I know it’s no end of encouragement to Garret. You’re an amazing team together!


  2. nice to see the good work. I am just wondering, you could have sheathed the boat with copper, too. what was the reasoning to take wood?


    1. We actually sheathed one of our previous boats in copper but because we fastened Rediviva with galvy screws we couldn’t copper plate due to dissimilar metals.


  3. Hi Ruthie, at first I though you were sheathing with copper but I’d better not say that too loud and give Garret any ideas! No body thinks about torpedoes worm any more but it hasn’t gone away. I remember a story about explorer Roald Amundsen’s boat ‘Fram’ ( Colin archer special with 6″ hull and 4″ frames 2″ apart) that had been designed to be iced in at the arctic sea. When it went to the tropics after WW1 it almost sank form toredo worm. Defiantly worth doing some protection. Cheers Warren.


  4. Sheathing is a great idea. Will you be doing the bottom also or relying on a coat of anti-fouling? The progress you two are making is fantastic. So looking forward to seeing the launch.


    1. Hey Matt, thank you! The sheathing will be from the waterline down to the keelson, so covering all the bottom planking. We will still be painting antifouling on the bottom on top of the sheathing. We may even coat the bottom with epoxy and then the bottom paint but that’s yet to be determined for sure.


  5. Wow, what a sticky mess… But in the end it was a wise decision. The boat will be like an ICE Breaker! Sending you guys hugs and good vibes from a wet, thunder storm soaked Pacific Northwest.
