Is this the end? Probably not!

Timeframe missed a bit

Well, looking back the first post here was on 8th June 2011, and we aimed to finish and launch by 26th June 2015 – planning was never my hot spot! We did change the goal posts in mid-flight (adding a sail, loo, etc, and stretching her from  a planned 16ft to almost 27ft to get everything in, but hey we did get there!), and on the 20th July 2020 we took her for a steam and sail on Windermere with a cameraman (Roger Heise from the SBA) on hand to record her 2nd trip under sail (thank you Roger).

Notes on the Steam Bit

Before I inflict an album of sailing photos on you, a couple of notes on the steam side, especially for Leak Compound builders….

We had been suffering with a loud knock through most of last year, and despite my efforts to engineer it out over the winter it announced its presence on launching about a month back – very disappointing. We narrowed this down to the LP slideways/”small end” connecting rod bearing. Inspection showed there was too much clearance in the crosshead/slideway and a few thou of wear and some galling on the crosshead pin.

So I re-machined the slide-way cover plates to close up the clearances and made a new pin – full of optimism we fired her up again to see (hear) no difference at all – very, very disappointing.

The galling suggested a lubrication problem. You might remember that we have a lubricator which has a separate pump for each bearing. The design for the engine means that a single feed to the top of each connecting rod has to deliver oil both to the crosshead slideways and to the small end (via a t-junction in the rod). My conclusion was that this results in most (all?) the oil leaving via the crosshead, as there is a lot more space there, leaving the small-end pin without sufficient oil. So I replaced the two pumps feeding the HP and LP crossheads with a larger (black-coded) version, delivering 0.1cc/stroke. Miraculously this cured the knock at a stroke! very happy!

We also replaced a leaking clack on the condenser, and had some (but only 6 to 7-inches) vacuum, so it was time to discover if the sail worked….

The sailing log

Grayling and BefurWe left Ferry Nab at about 10:00am and steamed south to pic up Roger from Windermere Marina and the Maltbys (Jill, John and grandchildren) from their boat house.

The Passage North

Then we turned north for a passage to Ambleside. It was a day of light winds (small gusts with moments of near calm blowing from the North). We steamed to just north of Belle Island/Bowness Bay, and then raised the sail and attempted to “beat” upwind…

Befur performed well, managing to claw her way into wind despite our rather poor sail handing (sailing friends are asked to cut us some slack as complete beginners when looking at these pictures, please).

(Larger versions of the images in the slide shows, are also included at the foot of this post…)

In the interests of keeping the flotilla together, we fired up the boiler to catch up with the others and steamed the rest of the way to the YHA pier at Ambleside for a welcome lunch and coffee…. Does it always rain in the North Basin of Windermere?

The trip south

We steamed off the pier to get off the lee shore, and set to on running back to Bowness with a slightly stronger wind – again she seemed to perform well, although we seem to be reefed down to 5 panels in all the pictures – you could even hear the wash from the bow and stern at some points  – high performance stuff…. Once in the lee of Belle Island at Bowness we steam/sailed the last half mile to Ferry Nab, and Roger’s provided bubbly – we were all very happy… (sorry about the fenders, we are really just not posh enough for the Winermere crew!)

Finally a few seconds of us attempting to tack upwind, with apposite commentary from Roger!

…and thank you all

Thanks to everyone (friends, SBA Members, JRA members and suppliers) who have helped us on the journey to 2020, with generous advice, support, practical help (work), equipment, and good humour)  – and thank you to Louise for allowing me the time (and money) for us to do this and her ever more skilful work as a seamstress, with cushions, beds, covers and that beautiful sail!…

Friday 13th – unlucky for us, and performance data

Lady Luck

Took Befur out for a tour of the lake yesterday, enjoying a day of early autumn sunshine. Conscious that it was a fated day, I was expecting some drama!

Lou managed to (very narrowly) avoid a dunking while we were boarding, so I thought we might of escaped. However, bad planning on my part resulted in us getting blown onto a jetty on the lake, which was (unbeknown to us) fitted with large bolt ends projecting out to catch people in exactly our predicament – so more filling, sanding and re-painting required over the winter to repair a pair of gouges in the hull – bugger!

Performance Testing

One of my objectives for the trip, was to collect some performance data, and the map below (click the link and it should open in google maps) shows the route and the waypoints with speed, direction etc. (clicking on these will give performance data for each bit of the trip).

https://www.google.com/maps/d/u/0/edit?hl=en&hl=en&mid=1qv-Q4JREXMB5lKKMXQmANtZhy-Hxu3DD&ll=54.607108645724125%2C-2.8355938095091915&z=16

The net of this experimentation produced data on two “stable modes” of operation.  All of this at a boiler pressure cycling between 185 psi and 225 psi.

For the record we are now operating with a gear-up ratio from engine to propeller of 1.45:1 and a 21″ x 19″, 3 bladed, left hand prop.

At “cruising speed”

At this speed we are operating with a HP pressure of 60-70 psi, and an LP pressure of around 16 psi and a vacuum of about 10-inches. The engine is turning at between 175 rpm and 125 rpm (when alternator is charging). The map tells us we are moving at about 3 mph (2.6 knts), it was running into fairly light winds, so this data seems realistic.

At “flank speed”

This is about as fast as I feel happy running the plant, and is resulting in the engine slightly outrunning the boiler with a sustained boiler pressure of about 170 psi.. HP pressure is 135 psi, LP pressure 28 psi, vacuum of 14-inches. The engine is turning at 300 rpm and the log tells us she is making between 6.5 to 7.2 mph.

…so with a computed hull speed of just under 8 mph we still have a way to go on the performance stakes.

Those with better maths than I might be able to turn this into some meaningful performance data for the engine hull.

We also had the time to check the depth sounder and it certainly seems to work, with the audible alarm providing some confidence for the helms-person when we are running out of water!

…onwards, it will be “dragging out” time in the next few weeks, and then we can fix the outstanding mechanical issues, ifx the knocks and bangs, fit the mast and figure out how to stop the water getting into the cabin roof!

A new generation of steam boater?

As you can see we had 3 generations on this trip…Good Friday Trip

Time to take stock

Well, as we approach the end of the 2018 season, we have decided to fetch Befur back onto dry land a little earlier than planned. This is principally because I can’t tolerate the racket the machinery is making underway, and it seems cruel to run it further pending the noise turning into a real “issue”.

…and it floats level!

We did have a nice steam this week about 2 1/2 hrs round the northern reach of the lake in a “fresh” breeze.  We were towing the inflatable (still nervous about our reliability) and this very nearly became airborne as we opened Befur up into the headwind – she goes quite well. Continue reading

AFLOAT AT LAST! OMG!!

After six weeks solid nagging from Malcolm I have finally been persuaded to write about our experiences on the ‘competent crew’ course. Not sure that this will be of benefit to anybody, but hey – here goes.

Part 1

Arrived at the school at teatime on Sunday. Felt mostly nervous and this wasn’t eased any by being the only girl amongst a fairly motley selection of blokes. There was ‘hairy Malcolm’ who we all know and love! John, an older chap (well older than us anyway) who seemingly had lots of experience. Ian, a very organised ex military police person now working in the NHS and Duncan the skipper who looked very chilled dressed in beach bum/surfer dude/not yachty sailor type togs.

Following the formal paperwork we were all dispatched to load the boat with food, clothes and other important stuff. We were given a safety briefing, sleeping arrangements were made and we were off. Too scary for words!
