How to drain the ice box?

Here is a photo of Windstar's ice box drain pump.  It is a Beckson SiphonMate hand pump, mounted in a bracket below  counter.   The inlet is connected to the ice box drain, the outlet to a length of hose which is not connected to anything, but  is long enough to reach the sink.




When Windstar showed up, the self priming SiphonMate was not.  Replacing it with a new one solved the problem.   It is a simple, effective approach, however I would prefer a drain that was direct plumbed into an overboard drain rather than relying on a coiled length of hose.   Pretty low on the list of issues, and mainly,  I post this for those who would like to see the stock installation of the SiphonMate.

A recent discussion on the C&C mailing list was started by an owner with a blocked ice box drain hose, which left me puzzled.  Drain where?  The bilge?  Nasty.  Turns out there were others with the same plumbing, (a prior owners' fix?) and others who had addressed this in different ways.

Below is Lee's solution, repurposing a seawater pump and faucet.   I expect the seawater pump was a dealer option.   (Windstar has only one footpump, from the freshwater tank.)

 "I have no need to have lake water at the sink so we repurposed the pump to drain the ice box. The hose goes from bottom of ice box to foot pump at foot of sink. This pump used to pull lake water in an dispense in the sink."

Cockpit VHF speaker without butchery

One item on my long list of things to improve was to ensure I could hear the VHF from the helm.  I have an aversion to cutting or drilling holes in a boat, and will do whatever I can to solve a problem without doing so. (drilling holes I mean!)   In this case, the solution was fairly easy - mount the speaker in the lid of an existing access cover.
The hole was cut using a flywheel-type adjustable circle cutter on a drill press.   I clamped two pieces of MDF in the drillpress (stacked) and cut a hole  equal to the cover plate's diameter through the first piece.  Removing the cut out created a fixture in which the cover could be placed, already centred under the drill press chuck.  I then re-adjusted the cutter to the correct diameter for the speaker hole, firmly clamped the cover in its fixture, then slowly bored the second, smaller hole through the cover.    Not for the faint-hearted, but it worked fine, and any lack of concentricty is not noticeable..
 The sound  is very loud and clear, the ICOM M506 VHF has plenty of power to drive this inexpensive Polyplanar speaker.

Port side settee stowage access




A 9600 lb racer-cruiser has limited stowage for even short cruises with more than 2 people.
One of the things I dislike about the 33-2 is the way the port side fold-out double berth impedes access to the only large stowage area in the boat.  In the pretty drawings, they don't show that the under the starboard settee resides only the fresh water tank, under the V-berth resides only the holding tank, and under half of the quarter berth resides one small locker and two batteries in a difficult to access locker.     The port settee is available for stowage, BUT the drop leaf table must be dropped, the seat cushions removed, and the berth extension folded out before you can lift the covers to access the stowage.  A nuisance!   Also, it's all one big compartment so the reserve beer and wine can crush the reserve potato chips.     (Apparently the water tank was moved to this side on later production years.)  

I wanted more convenient access to this settee locker, so I decided to add some hatches as you see in the photo.  I chose Tempress 1115 (11" X 15") slam hatches.  There are others, but these are:   "as functional as they are stylish"

Stylish!

See below for photos, fairly self explanatory.  I used a bimetal holesaw, and my fein multimaster with a circular bimetal blade.   Next step will be a simple barrier between the two compartments.

In future the chips will meet the beer only at the time and place of my choosing!

Navigation light - cable deterioration

The SJ 16/2 cable used to connect the bow and stern running lights in Windstar has not stood the test of time.  This cable is intended as portable cordage, and has rubber-insulated conductors inside a neoprene jacket.  The conductors'  insulation is crumbling and just waiting to create a short and tripped breaker. The prince of darkness lurks...  Will post pics, it's toast, and it's now gone.  

The PVC insulation used throughout the rest of the boat is fine, it's just the length from the light, through the pulpit/pushpit to the bullet connectors below deck, where the lights connect to the harness.  (the cables in the mast were fine also, except for some wear and tear at the base of the mast.   I rewired the mast in '17 anyway.)

The neoprene cable jacket is likely in much better condition than the conductors' insulation, therefore the condition of the conductors is not evident when simply inspecting the cable from the outside.  Check the conductors themselves where they are exposed.

C&C 33ii Emergency Tiller Refinements



C&C 33ii Emergency Tiller Refinements


Update

Stowage for the emergency tiller is documented here.

Dealing with the tiller


Ok, "refinement" might be a stretch.

C&C supplied a very nicely made alloy emergency tiller with the 33ii, and designed the boat so the top of the rudder post is easily accessed.   So, dealing with steering failure should be relatively simple - just slip the tiller over the post and till away.  Right?

Well, not exactly.    The cast aluminum tiller head's bore is a very snug fit on the stainless rudder post, and in my case, due to some very minor dings on the sharp edge of the bore, it was not possible to slip it over the post at all.   Even without those dings, once started, it was not possible to fully seat the tiller by hand pressure alone.   The tiller is secured by a stainless bolt that requires two 3/4" wrenches to tighten.  These were simply taped to the tiller.  (nothing to go wrong there!)    All things considered, not what one would want to be dealing with in an emergency.

So, I filed a chamfer on the edge of the bore itself, then sanded the bore smooth(er), and waxed it.  Hopefully it will slip more readily over the post.

I had intended to replace the machine bolt on the tiller hinge with some kind of shaft and hand knob arrangement to make it tool-less, but I got to thinking about it while some varnish was drying, and and I came up with a less elegant but workable approach.  Thinking about it, I'm not sure the hand knobs would have allowed enough force to secure the tiller, and while some kind of cam screw arrangement would probably be ideal, that was too far down this rabbit hole, even for me.  Besides, the varnish was nearly dry.  

An eye strap was riveted to the tiller head and a length of shock cord installed.  (using hog rings to make secure loops)  To this, a pair of tethered wrenches was ring-hitched.   The geometry involved and the tension from the shock cord combine to secure the wrenches, while permitting them to be withdrawn from the tiller if needed.  Ugly but functional.




Next iteration is to cut the open end off the wrenches, and bore holes for the tether.   This way the wrenches can be fully inserted in the tube.  

This provided a minor lesson in metallurgy.   I cut the wrenches down with an abrasive-wheel chop saw, but drilling proved to be a challenge until I annealed the ends with a propane torch.  Easy then.  The holes were drilled, gently countersunk, and any burrs addressed with a conical bit in a Dremel.   The handles were dipped in primer, then paint.

Canvas work, improving cockpit comfort.

Cockpit canvas upgrades


Update 

A panorama of the new-in-2019 cockpit shelter.




A dodger and bimini were must-haves on my boat acquisition checklist, and Windstar came with both.   Also included was a joiner piece to connect the two (usable only when at anchor as the mainsheet traveller is mounted on the bridge deck) and two zip-on side curtains that helped provide some shade and privacy.  Two stainless steel grab handles are mounted on the dodger frame.   Very useful.

The old canvas worked well enough underway,  however at anchor, when the connector was attached, the natural path for for rain water run off was onto the coaming and then into the cockpit.  This made the cockpit unusable in even a light drizzle, though  at least the companionway could be left open.  The side curtains were very basic and of limited benefit.  
When the dodger windows became opaque and the stitching began to fail in places, I consulted with Paul Macdonald of Bluewater Marine, and a dodger repair and a new bimini, connector, and side curtains were commissioned.
We collaborated on a new design for side curtains, much larger than before, with screening and roll-up Sunbrella rain panels.   Best of all, despite an awkward 3 way corner, where side curtain, dodger and connector meet, the rain no longer enters the cockpit at all, making for a remarkable improvement in livability.
I had also asked Paul to provide a means of securing the dodger window in the open position - flipped up and lying on the dodger roof.   
Paul is a pro who consulted thoroughly did nice work, and delivered on time.

Winter Cover Frame

I posted the photos below after a discussion on snow-crushed cover frames.    Turns out that not all frames were created equal.

Windstar's frame came with the boat, not sure of its origins but it works pretty well.   Remarkably, Dennis from Quinte canvas was able to make a cover that fit very well from my emailed dimensions.

Key to the frame's strength vs the more typical backbone-and-ribs are:

  •  the vertical posts supporting the backbone via a T fitting.  (same fitting as each rib half) which I tie in place at the foot so they can't move. 
  • the longitudinal tubing along each side, running through a crossover fitting.  The frame is bungeed or tied to the toe rail at every crossover.   
  • One of the ribs is (now) inserted into the stanchion socket.   (I figured this out this season, photos are a few years old.  You can see the 4th rib from the bow is beside a stanchion base.)

If I were to build from scratch I would size the ribs so that as many as possible could be inserted into the stanchion sockets, adding any other ribs between as necessary.

The frame pieces are stored clamped onto a length of tubing, the ribs in pairs.

I have yet to devise an part-identification system that I am happy with.

The component parts can be sourced industrially and are known as structural pipe fittings (or similar).   some links and images at the bottom of the page.

Working with shock cord

 The spinnaker pole rebuild triggered an investigation into shock cord.

Buy it.

It's not easy for the novice like me to tell good from bad.  What I managed to learn was that a dacron cover has superior life to nylon and is one of the indicators of a superior product, as is the amount of elongation that the product will permit.  Try it.  Cheap stuff does not stretch as far as the better stuff, and feels quite different.  OK, not exactly the definitive guide to things Bungee, but it's a start.


Cut it, terminate it.

To cut it, tape first with masking tape then use a hot knife.  I bought a soldering gun with a cutting tip on kijiji, and it works well enough. 

To terminate, use stainless hog rings and the appropriate crimp pliers.  Was not able to find these easily in Toronto, but in fishing communities where lobster traps are used and maintained they are commonplace, as are the better grades of shock cord.

Easy.   All the right stuff is in the photo below, followed by a shot of crimped hog rings on the original shock cord.



Old vs new.

When I dismantled the spinnaker pole and looked closely at the original cord, I could see a construction quite different than I was used to seeing.  See below.   The old stuff, (white) with two layers of braid looks as though it would have greater ultimate strength   and perhaps a more specific extended length than the new stuff.  the rubber cores are different as well.  Though obviously expired, it had not failed in use.  I expect the newer stuff would have snapped.  Perhaps this older style material still exists?

Spinnaker pole repair

This winter is focused on sails and running rigging:  new lines, two sails, a few other items.   One of which is the spinnaker pole, which I believe was original.  Its issues are plain to see:  It was damaged by being pressed against the baby stay at some point in its life, and the topping lift bridle is well past its retirement date.

How can I straighten the bend in the tube, and possibly (somewhat) press out the dent?

Tubing is anodized AL, 3" o.d., .080" wall, 2.83"I.d..   

This pole had no lower bridle.  Some do.  Should this one have one?

Thanks!






Was quoted around C$250 for a replacement anodized tube from a local chandler, but in a rare flash of inspiration I remembered an automotive tool called a pipe expander - meant for dealing with steel exhaust tubing.   C$35 later I was able to do a passable job removing the dent using an el cheapo  tubing expander from Princess Auto.  Misted it with silver paint as well, just 'cuz.

So far, have replaced the shock cord as can be seen above.  See tools and some detail below.

Gori 2-blade prop

My Martec was tired and I knew I wanted a folding prop to replace it.   Pretty happy with the Gori.  Do beware that the normal shaft section where the castle nut is installed may be different in length than a typical North American prop.  (the gears foul the end of the shaft on the gori, there is more space on the martec.   A long story but it took some doing to install this, and some mods to a brand new shaft.
In any case it works great, no issues so far.   Shipped air from Denmark amazingly quickly, great service from the agent in New England somewhere.

What are these used for?

Documenting my rig for winter work and a new mainsail, and it's like a box of chocolates...

Here is the gooseneck fitting from below - what are the two fairleads for? (Cunningham maybe?)

Another mystery item, this shot from the bottom of the boom.   The swivel padeye is the vang attachment.  What was the the cleat mounted forward of that used for?
Does anyone know who manufactured the padeye itself?

The next two show why it is a good idea to inspect the rig!  End of boom casting fracture, and mainsheet attachment rivet failure.
