I got up the nerve and installed the depth sounder. The first job was to bore a large hole for the transducer. I did this with a hole saw and all went smoothly. The saw was smoking by the end and I think is no good for anything more now. The bottom is thick, over 20mm, plus plastic flaps and a final thin ply layer securing the plastic in place. Quite reassuring to see how thick it is. I had to file it out slightly before the transducer would fit through. Then I smeared epoxy around the cut edge and, after that had set, pushed the transducer in place. I have fixed a square wooden plate on top of it which screws down onto the boat bottom. The whole thing is quite firm and the transducer face is almost flush with the bottom of the boat. Then I drilled a second largish hole in the main bulkhead for the display's electrics to poke through. Slightly unnerving to see the bulkhead is just a double layer of foam with epoxy/fibreglass on each face. It seems very strong.
To stop the plate on top of the transducer getting fouled in the sump, I have covered it in self adhesive copper tape. It looks lovely and shiny now, but I presume it will go green in the sea. I may tap in some copper tacks to hold it in place in case the adhesive works loose.
The display fits in neatly. It isn't possible to make the holes behind it waterproof. There is a foam rubber seal behind the unit which is supposed to keep water out, so I hope it works.
Then I had to wire it all up. I had no experience of doing this. I got small reels of wire and crimp fasteners from a car accessory shop. The instructions for the switch board were rudimentary. I traced everything step by step and finally wired it to the battery to test it. To my amazement it worked first time. Emboldened, I wired in the GPS unit and that worked too. Rather than risk messing it up by disconnecting things, I made a wooden box for it and managed to slot the switchboard in through the back and screwed it on he front. After much thinking I have fixed it under a side deck, next to the companion way. It slots in very neatly and can be reached from the cockpit. I have had to fit a wooden cover over the back of the display unit, to cover the wires and screws. I will fix a picture to it at some stage. I then spent the next half hour just turning things on and off and admiring the fact that everything works.
Having completed the wiring, I think I have just about finished all the jobs I had set myself for the winter. Now I "just" need to do the painting. I swept up all the leaves and dirt and washed the side decks. There is now a little painting to finish in the cabin. After that it is the topsides, the hull and a white antifoul boot top. Hope I can get it all done before launch. We go for a three week holiday at the end of March, so there isn't that much time.

Spray hood and depth sounder
I have fitted two stainless steel eyes on the cabin roof each side of the spray hood. With a lanyard through these, I can lash the hood down tightly when sailing (and towing). This helps forward visibility. It also means the lanyards are always there when you need them. I am aiming to have few or no short lengths of rope in the cockpit for sail ties, hood ties etc. These lanyards will always be in place, as will the bungy on the boom for stowing the mainsail.
I have bought a NASA Target 2 depth sounder
The photo shows the sounder, not fitted. The wooden patch shows where I plan it to go. Easy to see, won't get in the way of lounging back against the bulkhead and easy access to the wires behind. Wiring it up fills me with dread. Installing the transducer on the other hand should be relatively straightforward.
The BayCruiser has three flooded sumps at the stern of the cockpit. The middle one has a huge hole in the bottom for the outboard. As you can see in the photo, there is plenty of room for a transducer in the forward corner and no need to worry about keeping the hole water tight as it is flooded all the time anyway. What I am planning to do is drill a hole with a hole saw big enough for the transducer head to pass through. The hull thickness here is about 20mm in total (one layer 6mm ply, one layer 9mm ply and some plastic faring strips sandwiched between). The transducer head is about 22mm thick, so it will just be proud of the underside, so should have a clear view of the sea floor. I will fit a larger ply "washer" over the neck of the transducer, which will screw down to the hull around it and allow me to tighten the transducer holding nut. I need to remember to slop epoxy all around the exposed edge of teh hole to keep the seawater out.
It probably isn't the purist's location for the fitting as it is close to the engine and not at the absolutely lowest part of the hull. But the ability to install it without drilling through the cabin floor is worth it, I hope. The cable will pass through the fuel hose opening into the cockpit locker and I will have to drill one hole between that locker and the cabin to get it inside. Then all I have to do is build the switch board...

Solar panel in and getting ready for painting
I have mounted the 1W solar panel (£9.99 from Maplins) back on the roof. I have set it off to one side for a couple of reasons. Firstly, if it is central, where I first had it, it looks better, but it is directly under the boom when moored. Off to one side it has a clearer view of the sky so should be more effective. Secondly, when it was right in the centre I kept stepping on it if I went on the roof to stow the sail. I habitually climb up the starboard side, so putting the panel off to port gives it a chance of survival.
The 1W panel seems to be perfectly adequate for keeping my battery topped up for weekend sailing. I currently just run a GPS and a hand held VHF radio from it. I am seriously thinking of installing a NASA Target depth sounder, with a small switch panel. That will draw more current, so we will see if the panel can cope with that.
I have installed what I hope is all necessary electrical conduiting. There is a very thin conduit from the panel, over the roof to the edge of the hatch, and down inside the main bulkhead. That feeds into a slightly larger cross conduit, just below the companionway, which will allow me to run wires to either side of the cabin. The timber patch on the bulkhead to the left of the steel mug is where I plan to install the switch panel. The conduiting (all from Maplin again) is essential. I had bare wires strung over the place before and managed to wrap them round my foot and break my first solar panel. Now there is a place/conduit for everything and everything is in its place/conduit (I hope.)
One pleasant surprise. I have half a tin of International Toplac Ivory paint and half a tin of matting agent, both more than a year old. I had presumed one or other would be dried over and useless, but both are perfect. Not a sign of skinning at all. Mixing in the matting agent (which dulls the finish and looks really good) gives me a full tin, which should just about be enough for the superstructure this year. That saves me nearly half the price of the depth sounder... (it's economic calculations like that which lead to me not being in Forbes Rich List)

Work on stowing the spars, cockpit tent and permanent sail ties
A weekend of pleasurable fiddling about on the boat. I have finally managed to rig up a functioning set of boom gallows. The only concern I have is that they may not be substantial enough, but I think in practice everything will be tied down firmly and so they probably are.
First two shoes were made up from wood an plywood and screwed to the inside of the coamings on either side. Simple scissor gallows made up to fit in them, with the top angle shaped a bit to ensure the sail track is not squashed on the mast.
Then I screwed on the old tent hoop holders I made last year and slotted the hoop back in. Luckily it comes up just below the cross of the gallows, so I can have the tent up under the boom if I want it.
The tent itself is just a clear tarpaulin with a sleeve at the rear end for the hoop. The sleeve is just made by folding it over and taping it down.
It extends right over the sprayhood and should tie to the base of the shrouds at the front. I need to shap the front a bit to fit the hood more closely. How useful it really will be will depend on the weather. On the whole the spray hood is good enough.
The plan is that on a mooring the boom can rest on the gallows and stop the risk of the lazyjacks failing and the boom crashing. When towing, the main and mizzen masts will rest on the gallows and the boom will hang in a rope sling under the hinge. One end of the sling is fixed to the gallows. The other end goes through an eye, then up over both masts and hangs down with a loop in the end. The main sheet hooks into this loop and when it is tightened and cleated it holds all the spars rigidly in the gallows. The fore ends are supported at the tabernacle. It actually works quite well.
Finally, I have rigged a sail stowage system for the main sail. I have read of a technique of running two bungy cords along either side of the boom, and hooking them together over the sail to stow it. I have modified this idea to use just one bungy, down one side. this runs through five stainless steel eyes and is knotted off at each end, slightly taut.
On the other side of the boom are four clever spring closed hooks I spotted at the boat jumble, each about half way between the bungy eyes on the other side.
In use, the bungy is stretched over the sail between the eyes, and secured in a hook. It works really well. In practice it will depend on whether unwanted things get caught in the hooks or not for it to be really satisfactory. But it means you don't need sail ties to stow the sail. It looks a bit of a mess in the photo, but no worse than it looks with sail ties. With the boom gallows, it will all be much steadier, so I should be able to stow the sail more quickly and neatly than usual.

Various uses of a flat fender
I have got four Plastimo flat fenders on board. They are wonderful; as fenders, but also very useful cushions in the cockpit. To address a couple of minor issues, I have mad some very simple additions. First a solid board, with small rebates on the bottom, to act as a bridge deck below the companion way.
With a fender on top this makes the most comfortable seat on the boat. When sailing the crew can sit here with her feet in the cabin, fully sheltered from the elements. In harbour, if you put the lower washboard in to lean back on, it is a great lounging position in the cockpit. When I am cooking, I sit inside on the cabin table and have the cooker outside, on the fender and under the spray hood.
The fenders also give just that bit more forward visibility over the cabin top when used as side deck cushions. One problem I have had doing this is that when you tack, the leeward cushion slides under the side deck, so that when you tack again, you have to fiddle about pulling it back out. I have fitted two low ogee trims on each bench which I hope will just stop the cushions sliding back, without getting in the way too much. Only sailing will tell if they really work.
The boat is filthy with dirt, leaves and sawdust. I shall have to carry out a thorough clean before I can paint anything.
