In 1973, Sam Springer was said to have been topping his 36' boats in wood. We were told Pentargon was re-topped in steel at some point in the 90s and that the existing windows were cut in and older windows shut up! Looks 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 an archeological dig on 2012/3 to remove almost a ton of unwanted 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:
Waiting around for the cheque to be cleared in late January 2012 gave Pogue a chance to get some work done surreptitiously, on board in the marina, to plan future itineraries and be inventive. Pentargon is exceptionally basic and that is something you come to love about her. Her design, layout and use intentionally tap into "off-grid" and she could exist in an isolated spot without outside intervention for some weeks if necessary.
The engine, when running, whirls a basic 12V alternator from a 70's Peugeot, which then charges the starter battery and the leisure set together. A dedicated relay (Lucas 630) is employed to isolate the starter battery when the engine is not running or turned off. This ensures there is always punch to start the motor. In six years, the starter battery has never ever failed to start the engine in seconds ...
... unless the stop cable has NOT been pushed home after stopping the engine ...
A single track of robust electric cable goes down the length of the boat directly from the leisure battery bank supplying cabin lights as it goes this cable (rated at 200+amps) is routed down the keel under the sole plates to the front of the boat.
The fridge is supplied by a spur from the heavy cables, but may eventually be wired directly to the charging splitter, (to which it should have been attached originally).
(This edit is ongoing late Nov 2017!)
I though Pentargon was acquired 12thDec2011 but as of 11th Jan 2012, it was not yet mine.
It eventually came into my hands on 27th January, 2012
The new owner (me?) should be the 3rd since the boat was 'launched'.
Pentargon shows clear evidence of having been built by Sam Springer in 1972/3
but may have been not registered until 1976.
That would fit with a theory that she may have been bought unfinished (as a sailaway hull!) and the first owner took time in fitting the cabin and only registered it when ready to sail.
Most of this is speculation and only time and a lot of rooting will discover the facts? The fact that she has sole plates suggest work done by an experienced shipwright and evidence points to the floor having been laid at the time the hull was fabricated. The bottom lacks a keel as such but uses an ingenious bending of metal sheet to provide a slightly "V" bottom. (For rocket scientists ... the dihedral angle is 173º, and this sort of advanced solid geometry would not be expected in a simple steel tank shaped like a narrowboat! ... The designer and builder of Pentargon knew EXACTLY what he was doing.
12thJan2012 cheque gone in for clearing. Next week maybe I get a dotted line to sign on. The survey clearly showed up that Pentargon had bottom work misdone more than once in past years culminating in the totally botched 2002 job.
I got some numbers and engineering know-how regarding proper re-plating. It's accurate marine engineering but I have previous in this department.
I wanted the bottom re-plated in 6mm all over, to give her 25 years extra life.
6mm mild steel sheet weighs 48kg per sq metre. and about 18sq metres weighing 844kg.
That weight would take Pentargon down 2", lowering her CofG AND her centre of buoyancy
AND that might make her more steerable and less giddy.
All this and I have yet to actually sail her?
13th Jan 2011
To avoid any more botching of bottoms, it was necessary to find a specialist in Springer repairs.
He should have built the boat originally or at least drank in the same pub as the welders.
This happened during the 'chequewait' and plans were hatched to get the boat into dry dock for Feb06.
The delivery was fun. Out of the marina onto the Leicester arm and on to Norton Junction by the A5.
Yes! THAT A5. Watling Street! Which was to play such a pivitol part in the future history of Pentargon.
A couple of miles along to Braunston tunnel: 1¼miles of sheer terror for many narrowboat skippers. Down the set of locks passing the Admiral Nelson into Braunston and a Gongoozlers Rest Breakfas. n
8ml hike via Barby to Hillmorton ... to the dry dock at Galbraith's Bridge and PAUL DEMELLSWEEK.
In hindsight:- ............... if only it had been that simple.
However, in early May, Pentargon emerged with a full new bottom,
beautifully fitted by one of the best arc-welders in the country.
It emerged on budget because we ignored time schedules. . Nor had we any more money!
