Yanmar YSE12 Running in after complete rebuild
Very Nearly About Sailing
Just about sailing is simply a light hearted video diary of someone who has wanted a sailing boat for as long as he can remember. Then in 2015 I decided it's now or never. Let the adventures begin! I bought a lovely Mirage 28 which I recently sailed round the South of the UK (check the short series of 13 videos April to May 2017) to a traditional boatyard in Kent for a refit prior to taking her off to venture somewhere warmer. Who knows where the adventure will take me. I would be delighted if you want to tag along with me and comment.

This YSE12 was losing about 1/2 litre of engine oil per hour. It seized just off Oxwich Point and wouldn’t restart. Whole heap of trouble with the tide about to turn and darkness coming in. I have done a complete (new piston, rings, wet liner, valves etc plus reconditioned the injector pump and injector) re-build. This is at 16 hours running on the pontoon. It has started first time every time. Given the state of the piston and bore (top ring snapped in two and a huge gap between piston an bore) I am surprised it ran at all previously. It feels and sounds a lot better now.
Boring video unless you are building a YSE12 yourself (Or YSE8), but info on these old beasts is difficult to get hold of.
Next stage is sea trials after some modifications I talk about at the end.

VNAS November 2025 – Trying out LOMO waterproof panniers on Himalayan 411, Sanding a cylinder head
This one is mainly about some of the prep work I've been doing on my Royal Enfield 411 to get ready for some longer camping trips next year. I have been pondering on the 'best' panniers to get for ages; hard, soft, waterproof etc. I finally decided on the LOMO roll top waterproof pann...
VNAS October 2025 – a gentle ride out around the Trough of Bowland on my Himalayan 411 – lovely!
I spent a few days riding around the Trough of Bowland, and a few other places, with a motorcycling friend of mine. What a lovely part of the country, and a fantastic mini-tour with great company. This is just a short video of part of one of the rides.
