I’ve been playing with Inkscape. I rather like this picture:

Dinghy insurance for customized boats
I got a bit of a shock when I tried to renew the insurance for Custard – my junk rigged Wanderer. Insurance was refused. The boat isn’t worth much but third-party insurance is essential for my sailing club and many other places. The reason is simple – insurance is calculated by computers and something that isn’t in the computer is unknown.
A web search revealed that Fyne Boats had hit this problem and offered to help, even with boats that weren’t built from their kits. I contacted them and they responded quickly with a suggestion. I’m not sure if Fyne Boats get any money from referrals but their help is very welcome! The insurance is now in place and is cheaper than the previous year’s.
Fyne Boat kits do look lovely and I want to build one, one-day.

Holiday on Norfolk Broads
We’ve just returned from a holiday on the Norfolk Broads with the boat. Had a really lovely time – highly recommended if you are into sailing and / or boats. Having the boat moored at the bottom of the garden on a river, with a pub 1/2 mile down the river plus channels and lakes to explore, is a lovely way to holiday.
Some observations about the boat…
Continue readingMast finished, burgee halyard, anchor storage
I finally got the topmast plug out! Phew. Method was:
One. Buy a big drill from Screwfix.
Two: abuse my power drill and drill a hole through the middle of the plug.
Three: use an original 1980’s hot air paint stripper to push air through the plug as often as possible.
After a few days the plug came out. It is now fitted properly.
I also added a burgee halyard cleat:
Plus I’ve made a tarpaulin pocket to hold the anchor so it is ready for use next to the tapernacle.
Update: here’s the picture:
The anchor is a Guardian – a cheaper version of the aluminium Fortress. It was bought for a 21′ 1100kg boat so is a bit oversized for the Wanderer. However it is very light and I own it so that’s what I’m using. I use old climbing rope for the warp as (a) I’ve got 300′ of it and (b) it is very stretchy. The mount works nicely. I didn’t get the shank mount in quite the right place but it fits ok.
Oops – I get things wrong
Gluing inside a tube
Gluing the wooden plug inside a tube ended up with the tube jammed inside the tube. I had to cut it out. I suspect that if I had left it long enough it would have slid out again.
Jammed plug (again)
This is a stupid one. Having got the wooden plug stuck in a tube, I then got it jammed inside the bottom of the real topmast. I figured that I could put some wood preserver on it and tap it into place before it swelled up. I was wrong – it is very well jammed now 😦
It is slowly shrinking down again as the wood preserver dries out, but the bit inside the tube isn’t shrinking quickly enough to meet the deadline.
If it doesn’t show signs of shifting in the next few days I’ll have to cut the end off, then cut out the wood from inside the topmast tube (very carefully!) and make a new one.
DIY surgery
Really stupid time – I was cutting the end off a pipe for the bilge pump and the knife slipped. Ended up in my stomach. Fortunately:
- The NHS is fantastic – the ambulance and A&E did a great job of looking after me and stitching me back together;
- I have enough of a spare tire to prevent the blade going all the way through so stitches were all that was needed.
It is healing up fine. Main lesson is that never do DIY when tired – I hadn’t slept much the night before.
Free-standing mast – topmast stress concentration
There is a stress concentration in the topmast tube where it leaves the main mast tube. This wouldn’t matter, except:
- The topmast is thin aluminium so isn’t particularly robust;
- There are scratches in the aluminium at the critical point from when I made the mast;
- The topmast is already a bit over stressed in this design so as to reduce the weight at the top of the mast.
To stop the topmast buckling I’m making a wooden plug for the critical section from my last piece of decent Douglas Fir. The plug is in two halves glued together which allows the middle to be hollowed out. To allow initial working I screwed the two halves together.
After considering my options I made this on my metalwork lathe. This made it easy to get the outside to the right size along the whole length. I used metal-cutting tools – not elegant but gets the top done.
Next stage was hollowing out the middle. For reasons of speed I used my milling machine.
Then finished off with a powerfile / mini belt sander.
The mini-belt-sander is a very useful tool – I wish I had bought one years ago. Mine is Silverline – one of the cheapest – as it was light and compact for getting into awkward corners inside the boat. It has been excellent – highly recommended.
I’ve glued the two halves together inside a spare tube so it all lines up. I used Tightbond (waterproof PVA-type glue) as this should be fine in the conditions, is nice to work with and won’t stick to the spare tube (I hope!).
Once the glue has dried I’ll cut the square end off, neaten up the insides as far as possible and then put some wood preserver on it. It can then be inserted into the topmast.
Hopefully Custard will then be good for high-speed full-sail surfing!
