The design/development and building of Befur’s sailing rig. This is a modern development of the ancient Chinese Junk Rig design

A Start on Befur’s Sailing Rig

Time to make a Yacht!

Following on from appearing to have (temporarily at least) sorted the steam plant, it’s time to get on with fitting Befur with her Junk-Rig sails, so that she can truly be the Steam Yacht that she was always intended to be. The embarrassment of having to be towed home on three occasions also sharpened our desire to get this job done. Continue reading

Mast Ordered!

Today confirmed the order for the mast for Befur. A 6.4metre extruded alloy lamp post!

This is an unstayed mast, to support 16sqM of sail. Spent a long time trying to figure out how strong it needed to be – then suddenly realised it was much simpler than trying to figure the maximum wind load on the sail (guessing at maximum wind speed we might encounter) and realised it only had to be able to capsize the boat!!!

So the answer was a 177mm diameter, 4mm thick lampost, that tapers down to 90mm at the head.

Also reached the point where we could compile a list of the 70-odd outstanding jobs to finish Befur and divide these into Jobs to be done in Hampshire and jobs to be done once we have relocated to Cumbria. While it’s a daunting list, at least it’s fairly complete.

Fuel Tank, Mast Structure and Galvanizing

This is a hotchpotch of notes on progress we have made in the last few weeks.

I am now focusing my attention on the internal fit-out. We need to get Befur in a state to move her on a trailer to our new home in Cumbria in August, this is adding some needed pressure, to ensure we get everything done in time… Continue reading

Fit-out and Steelwork

Fitout

The current process is trying to finalise the major items in the fit-out of the boat, so that I can install the major structural elements for the cabin and mast. This is a bit of a “round in circles” process, You imagine how it will be, draw it out, see it doesn’t fit, imagine it again etc. Clearly some items will fall out later in the process, but we do need to get the mast, boiler, engine in the right place and make sure that one is not sharing the loo (head) with the other members of the crew or a few hundredweight of hot steel!

Mast Partners and Step – CAD/CAM

As noted in the last post, the plans for the cabin/mast arrived from Selway Fisher. Having poured/poored/pawed?? over these for a few weeks we have concluded we are going to slightly modify the proposed arrangement by installing a set of steel bracing inside the boat to support the Mast Partners (the thing the mast hinges in when being trailered), so that we can reclaim a little more internal space. We understand this is another bitter pill for the wooden boat druids to swallow, but hey, this is the 21st Century! Continue reading
