Training!!!
Fuzzy now rigged but just like last weekend the weather gods are not playing with their Cherubists. Shame on them.
Now got the rig looking something like it should. See the pics from last nights play.
I think this is the first time the sails have been put on the mast.
The pole is borrowed from SDzzz and not quite long enough for Fuzzy.
Waiting the wind... sorry not coming to play at Weirwood as too much to sort.

Fuzzy's first trip ended in...read on
Went to Rutland today, weather beautiful. Perfect Cherub blasting. 15 knots ish. Had a few problems and back into the mending shop for the amateur to cock it up again.

The gantry exploded into 9 pieces! Exactly on all my joints. Although I drilled the tubes I only epoxied them in and then filleted round them. Big lesson learned. I think if I carbon towed and peel plied each joint then filleted it would still be in 1 piece! From this lesson I am going to beef up some of the other areas as well.

We tried a long rudderless sail back the shore made it some of the way but ended up being rescued after Joe got a full dagger-board in the face, as it kept springing up out the slot when no lateral pressure was on it! (another mod needed) Joe now thinks we are jinked at Rutland, but 3rd time lucky soon, ASAP!  No hospital job but he was quite shaken up by it.
The safety guy was one of the crew from the open, excellent service and great guy.
Other than that a brill sail and we quite liked the boat as well. surprisingly a very stable platform. Rig is excellent. In the end Fuzzy should be a very good boat.

This lesson has to learned again again: Gantries need to be really strong - and the forces aligned properly too.

Think in terms of the joint having about as much carbon on it as the tube from which the rest of the gantry is made. So if the tube is 1mm wall thickness, think about 5 layers of carbon at the join with them finishing at different points along the tube.

For Atum we used tow from some v heavy (?600 g/sqm) twill we were given. I think we used 3 completed layers, one one axis and the other two a bit off axis each way on each joint. This was to join 25mm tubes together. The joints were made to fit by using a jig to hold one tube and an off axis holesaw (on a drill). The hole saw simulated where the other tube was to go, so you ended up with a nice snug fit.

For Antidote Andy P made an incredibly light one which did work and has been widely copied. Have a look at Usagi's one. This has got to be easier to make and loads lighter than Atums one.

Good luck!

Fuzzy had a brand new super long pole made by cookie after the 9er one broke in the big accident of 09...

our new gantry worked well and made no odd sounds in our test sail at hayling yesterday. 

was built with tubes and 3d printed joints covered in carbon.
