Pondering the Post-Apocalyptic and Whether I Will Need Bridge Swings



I have finally abandoned a requirement I imposed upon myself from the very beginning of the Autarkia project.  And that was to have a mast that can fold down from a tabernacle, so that I could easily get in under the local bridges.

This stemmed from fears of a post-apocalyptic Lower Mainland BC, where in this chaos - if bridge swings were still possible at all - they would be controlled by trolls and overlords - requiring me, in the dark of night, to stealthily sneak under.

There!  I now admit that I have gone overboard in a train of thought mostly born and fed by reading to much Dmitry Orlov, James Howard Kunstler, and others.   No, I am not a doomer.

That said, I still believe that we are in for a heap of trouble nonetheless that will include predominantly a financial crisis.  I predict though, that most infrastructures (including those involved in transport) will remain intact and functional.  So, the bridges will still swing.

So to move on with getting Autarkia a sailing rig, I intend to have her masted at least this year.  I am presently making inquiries and getting quotes for a steel tube, and the cost of getting it hot dipped galvanized.

Details to come....

Off Center Board Installed and First Test

Yesterday, My son Wesley and I brought the board down to the boat.  It is quite heavy, and the two of us huffed and puffed a fair bit to get it from the pickup truck, up and over the dyke and down the ramps to the dock.





I had previously turned the boat around so that the starboard side was against the dock so we could set the board in place.


Since the board, despite the weight, has a fair bit of buoyancy, it was not too difficult to get the bolt through the hole in the hull.  I smeared everything with lithium grease.  Once the nuts and washers were in place it was easy to push the board under and haul it down vertical with the line tied through a hole in the leading edge at the bottom.  There is a similar line on the trailing edge to use as an uphaul.


The bolt hole is reinforced with some angle steel lag-bolted to the stringer.  The only load on this fitting is the tension on the bolt.  The board bears against the gunwale at the top, and at the chine at the bottom.  Both are very beefy structures.  With the bolt snugged down tightly the board is very stiffly held in place.  Yet, I believe that it will 'give' sufficiently should it collide with an obstruction.



After the install Wesley and I took her out for a little test outside of the harbour.  Compared to when we brought her in last October, the boat was much easier to handle.  At speed, she turns on a dime without skidding at all!  Sharp turns to starboard have avery tight radius that is only slightly larger turning to port. Nonetheless, she is a heavy boat and there is a some delay in her response.

We will take her out again soon, and document it with lots of pics and maybe some video in an upcoming post.
