Here is one way of ensuring you have power for charging phones and running GPS independent of the boat. The yellow device can also act as a jump start for a dicky starter battery OR even supplement or replace the leisure circuit.
Seems like a keen piece of emergency kit for someone buying a typical budget narrowboat where nothing works or can be trusted? The fuzzy photo is intentional so that you have to ask me to produce a working copy of this. Someone has to pay for my electronic wizardy!
While cruising, the device may be clamped across the starter battery so IT gets charged "a priori" by the alternator. The cig-lighter sockets are very simply wired across the croc.clips to provide a 12v supply which can be left of the roof
Only six years ago, the only practical way to keep in touch with the outside world while cruising was by mobile phone. Provided you had a signal and a charged phone. Believe it or not while moored in Braunston , I had to climb 150' vertically upwards to the village in Jan 2012, the day after I had taken ownership of Pentargon. The boat had no way to charge a phone and I had noted this the first time I saw the boat. It was part of its magic simplicity!
But needs must and part of the deal with SWMBO was that I would be able to arrive home within six hours of a domestic emergency being declared so I needed to find a way to ensure I had a charged phone and a signal.
SAM SPRINGER ... UNSUNG GENIUS OF THE CUT
This article contains hotlinks to give extra information or explain phrases.
In 1973, Sam Springer was said to have been topping his 36' boats in wood: well, the ones he actually topped and they were not many as most boats left Market Harborough to be completed elsewhere. It is rumoured that Pentargon was topped or re-topped at some point in the 90s and that existing windows were cut in and others shut up! Pentargon does look like a steel top from a longer Springer was dropped on an older hull. Hence the unique lines and the tiny forward deck. Or so the story goes. During a 2012/13 'archeological dig' to remove almost a ton of un-needed concrete slabs from the bilges, we were unable to unearth any evidence that the original boat had EVER been tampered with. For the moment it looks as though Sam worked his magic and produced the ultimate Springer: a narrowboat that can go to to the most inhospitable inland waters in total safety.
She's been tested in Class D water and has behaved impeccably in sea trials.
In 2007, at Gailey Wharf, the freeboard was raised to 750mm to comply with "Class D" (as defined ) Cat.C is as far as we take her and that includes "inland" tidal rivers, estuaries and lakes and lochs where significant wave height could 'not be expected to be more than 1.2 metres at any time'.
Cat D: refers to tidal rivers and estuaries where significant wave height could be expected to be 2 metres.
Cat D is found in a very few areas.such as the Thames Estuary, the Bristol Channel and the Humber and has Summer and Winter specs. but to give an idea, Pentargon's airdraft is about 2.3m and that is the vertical distance from the water surface to the highest point of the roof! She has weathered bow waves from Thames Clippers in the Greenwich Reach and elsewhere in excess of 2m!
Pentargon is a much larger boat inside than is apparent from her 36' overall. She is constructed with a bulkhead to gunnel height separating the engine room from the galley behind which is cruiser deck: 8ft of cruiser deck. But the inside space is larger than found on most 42' boats as there is no waste in the bow. The main bunk goes right up to the fire-escape window!
With over 6'3" head-room, her discrete fore-cabin (with en suite bathroom, Hampshire heater, wardrobes and storage) can be isolated from the aft cabin where the mess and galley co-exist with considerable storage and bunk space. Pentargon is built for two in luxury with an addition crew bunk on the sole plates under the main bunk, but she can accomodate two more with the galley bunk made up!
On-board there are only two of anything: cutlery, ware, table space, seats, steam cookers. glasses, chairs Also, everything of board has two uses; if it hasn't its days are numbered. A glass flower vase holds EXACTLY enough water (150ml) to make a cuppa and the mugs hold exactly that amount of tea, coffee, cocoa, soup or whatever and THEY double up to hold the right amount of weetabix for breakfast.
During 2013, Pentargon's front cabin was extensively modified to fit a 4'6" memory foam mattress on a slatted [IKEA} base, raising the bed level up to the gunnel line thus permitting a view out the front window. An auxiliary bunk was fitted below and athwart for Pogue's personal use in exceptionally cold weather. And ... within this under bed space resides a black plastic tank which can hold enough drinking water for almost a years' cruising in keeping with the stated aim of living 'off grid'.
The Hampshire was tweaked, modified and repositioned to provide warm air heating to the space under the bed. Pogue found that the Hampshire had originally been heating the ceiling exceptionally well and the floor not at all. Over time an ingenious heat trap was made from marble slabs cut by a monumental mason in East London. Now the cross bunk and water tank can be made warm and the the water retains heat for quite some time in operation as indeed do all the furnishings and contents.
