Doing Some Drawing Since It's Raining

It's been raining a couple of days now and will likely continue for another couple so I thought I would do some finalizing of the construction detail for the next little while.

But first, since my last progress post I thought I'd put up a few pics of what I've done so far.

Motor Transom Mount

I laminated four layers of 1/2 inch fir ply with epoxy and then covered it with 10 oz cloth.  Aluminum angle and stainless bolts complete the assembly.

I schmooed it all up with PL Premium before bolting it all in.

I also got a start on some of the decking and deck framing.  It all went together with PL Premium and epoxy coated deck screws.  I painted the framing and prepainted the underside of the plywood before putting it down.  I did not paint where the PL would go.  There will be a second layer of plywood which will go down with Titebond 3 and screws.

I can probably get working on finishing the deck on Monday.  It is supposed to be sunny.

Yesterday and today I worked on this Sketch Up model with a somewhat revised interior.  It provides a convertible dinette with the wood stove nearby, and standing headroom right across the aft cabin.  The forward stateroom is lower but we are only sleeping or pooping there.

There is a crazy amount of storage space in this boat!

Well,It Had to Happen...

But, I'm not bitter.

This afternoon I was in the process of crawling under the ass end of Autarkia to do the final fitting of the outboard motor transom mount, that because of the bolt throughs, would be much easier to accomplish prior to any decking being installed.

From my low vantage point, I was able to see a white pickup truck pull up to the curb then some legs with feet attached to the bottom ends thereof approach up the driveway.  By ducking a little lower I could then make out the "District of Mission' logo on the side of the truck.

This seemed to be somewhat ominous.

It was.

The bylaw officer was quite good at his job and very diplomatic.  However, long story short, I've got about three weeks to get Autarkia the hell out of my driveway.

According to the officer, they don't really care about anything unless there is a complaint.  Apparently Autarkia is generating a fair number of them.  I'm convinced it isn't my neighbours, all of which I know well.  But we have a well traveled pathway through a small playground at the end of our cul-de-sac and I suspect a poodle walker or such may have had a worry that Autarkia would topple from her shoring and squash the little bugger while he was pissing on one of the supports.  You see, safety was a major concern.

Well, apart from the $500 or so it will cost to move her, I'm not in bad shape.  Tim, my old landlord where I built her will gladly take me back.  In the meantime, balls to the wall getting as much as I can done right here, right now.

Another Titebond 3 Experiment

In the process of cleaning up and organizing my shop in order to continue building Autarkia I had the spontaneous urge to make a test with 10 oz fiberglass cloth - which I have yards and yards of - set in Titebond 3, which I can buy at a very good price.

Here is what resulted:

I simply laid the cloth on the plywood and poured on the Titebond 3, and then worked it in with a 4 inch foam roller until I felt that it was well saturated.  Quite easy and not much work at all.  I peeled up that corner after an hour so I could have something to grab to try peeling again once the glue cured after a day.  Well, I tried after a day and it is impossible.

I am very pleased with the result.  I will use this on my decks and superstructure.  The superstructure will be painted with acrylic latex, and I will use a sundeck coating instead of paint on the decks, since it has non skid properties.  I'm not worried about seeing the texture of the cloth so will make no attempt to completely fill the weave.  I'm certain this will be durable and long lasting, as well as easy and economical to do.

Rig Options with Stayed Masts

Since I have decided finally to go with stayed masts and can design the masts and rigging with far more confidence than an un-stayed setup, the doors open to more options for a rig.

I have not thought about a bowsprit before - mainly because it greatly increases my overall length - something to avoid if one moors in a marina.  I'm not sure if we will or not, but a bowsprit allows us to carry a jib, and if we did, why not make the mainsail larger than the foresail and call her a schooner?

If I use Dennis's idea of using the lazy jacks as temporary pivot aligned side stays to raise and lower the masts, then I can get away with five stays for the whole rig - two aft side stays per mast, a running fore stay, and then a running triatic between the masts.  I could lower the aft main mast by simply easing the running triatic - no gin pole required - then lower the foremast by easing the fore stay.  We'd need a gin pole for this one.  Both masts would have to be on the centerline to use a triatic, and the foremast would lay over top the aft one when down - a bit cumbersome but only endured long enough to get under the bridge.

RLW in an email, put me onto using Amsteel rope for the stays instead of galvanized or stainless wire rope.  I never knew about this stuff before and it would certainly work well.  I can't believe how strong it is and it even comes in colours!

See the specs here:

Food for thought while I get organized to continue building.

Commitment Issues...

I'm ready to start building structure again, as the inside of the hull has been cleaned up, with nooks and crannies shot with copper preservative and painted with Dulux Weatherguard gloss exterior acrylic latex paint.

The next step will be to put in the deck beams and then two layers of 1/2 inch marine fir.  She'll be decked over fwd of the forward bulkhead and aft of the aft one, and 18" up either side.  At that point she'll be very stiff, and I can cut any opening in the bulkheads I want.

I must finalize my decisions with regard to the rig however, because I must make some decisions structurally.

Here is where I am right now.

Each of these sails are 250 square feet, and the design is from Derek Van Loan's book 'Design and Build Your Own Junk Rig'.

One of the biggest problems I have had with designing this boat is trying to come up with an unstayed mast arrangement that can be dropped easily for the bridges.  At this point I have given up on the idea of unstayed masts.

So my idea now is to use 3.5 inch schedule 40 aluminum pipe for the masts.  They will be about 25 feet long and will be simple stepped on the cabin tops with a bolt pivot.  Each mast will have six stays.  Here is why:  The middle two stays will be redundant except when raising or lowering the masts.  They will attach to chain plates that are directly in line with the pivot pin, so that the masts are always supported laterally as the mast is raised or lowered.  The aft stays do not get detached during lowering and are simply allowed to go slack.  Only the forward stays are uncoupled to lower the masts.  A gin pole arrangement will assist in raising and lowering.  Each mast will weigh around 75 lbs so they won't be difficult to handle.

After pricing out sails, I think we'll sew them ourselves too.  Might as well save some moolah.

Another thing that I have decided:  The decks and cabin structure will be covered with either polyester or acrylic cloth set in Titebond 3, and then painted with exterior acrylic latex.  I might use a sundeck coating on the decks instead.

Gotta get her done!  And if I hear another 'ark' comment from a passer by I'll 'splode!

First Miserable Job Since Starting

PL Premium is great stuff.  A lesson that I'm learning the hard way is that it must be cleaned up as you go.  If not you can be doing this for a while - like me for the past few days.

The only way to clean up the beads that have oozed out and cured is with a chisel and hammer.  Tough stuff!

Even though most of it will be hidden anyway it would bother me if it wasn't neat looking.

I get a lot of questions from passers by so I thought I'd put a little info out there for them...

Anyway, another day of chipping away then everything gets sprayed with wood preservative before painting.

At Home Finally

Just delivered but not yet leveled up...

And some more sketches...

And all leveled up and tarped for the showers... but sunny days coming!

Now That She's Upright

I'll likely be bringing Autarkia home in a couple of days and getting her leveled up in the driveway.

Since she's been right side up though I have had a rethink on how I may finish her.  Previously I had drawn her with a cavernous interior that would be pretty cool no doubt, but at a compromise now that I think about it with regard to the exterior function of the boat.

So I got going again with Sketch Up and re drew her with a walk around cabin.

To keep the lines aesthetically pleasing I had to lower the trunk cabin, but kept it high enough for standing headroom in the galley.  I still get a commodious interior with a queen size berth forward, a lounge with settee and dinette, and a large functional galley area with enclosed head and a hidden 'bath tub' under a counter or chart table.

This would go together quite quickly.  Since the trunk is eight feet wide, full sheets of plywood could be used here, and the roof could be a ply/foam sandwich - very strong and no beams inside.  Views to the outside are still accommodated with large, sitting eye level windows.  The only downside is that moving about the forward cabin will be in a crouched position.  But we are only sleeping or sitting in this area.  We have total standing comfort where it counts.  I have also decided to make provisions to steer the boat from inside the cabin as well as outside.

Both Lorri and I prefer the looks of this boat over Autarkia's original design

Here is a very crude and un-detailed conceptual drawing of the interior.  I can make the queen size berth for and aft oriented and have access to it from the side rather than the foot as previously drawn.  For the most part I can work with the existing bulkheads as built, cutting them down as required.  The fore, aft and side decks will all be a monolithic structure and will stiffen the boat immensely.

One other advantage of the side decks is that we will now be able to pole her along in water too shallow for the outboard auxiliary.
