Went sailing

I didn't get a lot done last week as I went for a trip round to Stangate Creek on Wednesday stayed overnight before sailing back to the Swale on Thursday, the weather was cold and damp but I did get to try the chart plotter WiFi connection in anger, as the holding in the creek can be a bit iffy I left the chart plotter on with the anchor drag alarm set and took the tablet to bed with me so that when the tide turned and the alarm went off I didn't need to go outside to see what was happening isn't this technology wonderful?

I did manage to screw and glue the right hand vertical section of the forward door frame in place last Monday and hang the door so that I could measure for the left hand vertical section and then over last weekend I cut the timber to size and drilled the screw holes

Door secured to right side of frame

I arrived back in Conyer last Friday with a bit of an oil leak from the joint between the casting which holds the oil filter and the cylinder block so the first task non Monday was to remove said casting and investigate using a flat plate and marking blue indicated that there was some distortion to the flange which had also led to some corrosion to the lower edge.

The high spots can be seen around the holes for the securing studs, this particular casting is not an altogether good example of British engineering design. The flange was fairly quickly straightened up with a few strokes of a smooth file and replaced with a new gasket,while I was at it I changed the engine oil and filter I finished up the day on Wednesday by sucking up the oil from the bilge before giving it a good clean with some industrial strength detergent.

Today I got back to the forward heads door and started by screwing and glueing the top semicircular section of the frame into place followed by a trial fit of the left hand side vertical section of the frame.

The latch for the forward door was long gone when I bought the boat it had been replaced by a collection of barrel bolts, knobs and handles I have been looking for something similar to the original, which is still in place on the aft door, I eventually found one on the Force 4 chandlery website which arrived today it is not identical to the original and doesn't have a key operated lock although it can still be locked from the inside.

Replacement for forward door

I finished up the day by removing all the old door furniture from the forward door, on the original installation the door locks were fitted on the outside of the heads doors but on the forward door I am going to reverse the set up and to cover up as many of the redundant holes as I can I shall make a stainless steel plate of the same footprint as the new latch. I don't know quite why the latches were installed in this manner because it means having a cut out in the door stops to accommodate the latch I may well look at reversing the arrangement on the aft door, unfortunately the doors are not thick enough,at 20mm, to accommodate a mortise latch

AIS

The first job on Monday morning was to install the NMEA 2000 backbone kit, the power cable and the drop cable to connect to the chart plotter are only a metre long which limits the position of the backbone, I ended up installing it in the cable void next to the AIS unit I still had to extend the power cable which was just a couple of through crimps the only other option would have been to obtain a longer drop cable to connect the chart plotter and as I already had some suitable power cable it was a simple decision.

Backbone installed and connected

Once the cables were connected I switched on the power to the NMEA 2000 system and then switched on the chart plotter, the GPS in the AIS unit took a few minutes to lock on to the satellites but eventually a number of ships appeared on the plotter screen shown as triangles on the photograph below the top two are not really on top of each other they are the tugs tied up alongside each other in Sheerness

When I got home I checked on the Marine Traffic website and sure enough a mauve circle indicates New Morning tied up to her berth.

Last weekend I made a start on cutting out the segments to make up the semicircular part of the forward heads door frame. these were then drilled for dowels before being glued together with some thickened epoxy before being clamped up between two pieces of laminated chipboard to keep the whole assembly flat.

Segments dowelled and ready for glueing

Once the epoxy had cured I marked out the top radius and roughed it out with the jigsaw so that on Wednesday I could fit the top section of the frame into the opening into the bulkhead, I temporarily screwed it into place before setting up the door in it's correct position so that I could mark out the top radius of the door on the frame. I clamped a piece of timber across the door opening at the correct height to support the door in it's correct position before marking the lower edge of the frame.

Door in position temporarily

While the door was in position I measured the width of the right hand vertical section of the frame and marked the position of the rebates for the door hinges. The next stage was to cut the timber down to the correct width and cut out the rebates for the hinges so that this morning I could temporarily install the right hand vertical and attach the door on a couple of screws to make sure that everything would fit and the door would open and close.

The plan for next week is to permanently install the right hand side and top of the frame, with screws and thickened epoxy. so that the door can be properly hung I can then measure and cut the vertical frame for the left hand side of the door, once this has been done I can finalise the cover strip to cover the joint between the frame and the bulkhead opening, on the forward face of the bulkhead this cover strip will overlap the frame by about 5mm to form the door stops.

Best laid plans

This Monday morning's visit to the recycling yard did not prove very fruitful they had some larger sections of hardwood but I do not have the means of ripping it down so back to the drawing board. Over last weekend I did manage to progress the door frames a little by making a couple of templates for the segments for the top of the frame, I drew the required arch on a sheet of thin ply so that I could ascertain the shape of the segments, the templates were cut from an odd piece of the 4mm laminate used for the bulkheads.

There are two templates shown the wider one is for the aft door where I am aiming to form the stops as part of the frame, the forward bulkhead is thinner and there will be insufficient thickness in the frame to rout the stops, they will be formed by having the cover strip overlapping the opening. The photograph of the layout for the top of the frame is not very clear but it is possible to see the development of the segment.

The first job on Monday when I eventually got to the boat was to fit the latch to the drop in panel under the cooker and then apply the first coat of varnish to the edge trim. I finished off the day by fitting an LED light fitting into the end of the cabinet housing the engine panel to provide an over bunk light for the quarter berth, I had found this fitting amongst all the other stuff that came with the boat and have been looking for a use for it not wishing to throw it away.

Quarter berth light

The first job on Wednesday morning was to put a second coat of varnish on the edge trim for the drop in panel before moving on to installing the AIS transponder. Some time ago I bought an AIS transponder when Cactus Marine Electronics were having a 'virtual London Boat Show special offer' this years show having been cancelled and I decided that it was time to install it. I started by fitting the aerial to the pushpit and running the cable through the aft cabin via an Index Marine deck gland, I find that these are much superior to the 'waterproof' plugs and sockets.

The cable was then run above the quarter berth headlining as far as it would go so that I could site the transponder unit, this has a built in GPS receiver which will work inside the boat provided that it can see the satellites, it will apparently work provided there is only a layer of GRP above it electrical fittings etc are to be avoided. I have sited the unit under the quarter berth just aft of the chart table, as this is as far as the aerial cable would stretch, one of the disadvantages of centre cockpit boats its a long way to the transom, the indicator lamps will be visible with the chart table in its working position.

The transponder is only temporarily fitted until I can finish the installation by installing the NMEA 2000 backbone and check the GPS reception.

On the way to Conyer this morning I went to a timber merchant and bought some meranti, an African hardwood, for the forward heads door frame so that this weekend I can make a start on the top of the frame, if this is successful I shall obtain some more for the aft door frame. The first job this morning was to wire up the quarter berth light at the moment it is controlled by a spare switch on the engine panel. I finished off the day be pulling the AIS data cables through to the back of the chart plotter which is where I aim to site the NMEA 2000 backbone providing that its power supply cable is long enough to reach the electrical panel, the backbone kit arrived today so that on Monday I should be able to connect everything up and test it.
