Ouchh, It sounds as if Weaverbird could use a couple of inflatable  sausages, and a compressor... or a set of big wheels...

Anyway, it appears we can thank the British Isles for the modest tides here. I read somewhere that the tidal wave coming up the English Channel and the one which rounds Scotland  cancel each other  at the coast of southern Norway. Many thanks!

The scene of Weaverbird drysailing on the (semi-)hard is quite surreal to me. I have often congratulated myself with the luck of living in an almost non-tidal zone (around 0.5m). However, I can see some advantages with your half-tide moorings, being able to scrub the bottom being one of them. In addition it must be fine to be able to inspect the mooring chain whenever you like. For us, that means diving. Do you actually need to use anti-fouling at all?

Anyway, good luck with tomorrow’s first sail. I notice you have given the sail a generous lead. I hope she balances well with that.

PS: How wide is the time slot when you can sail to and from your mooring?

Seems like you'll have great visibility beneath the sail. Well crafted.

Now I've got to the fun part, at last. I spent the morning rigging the sail, and everything went well. There are a few adjustments to make on the topping lifts, but most things look OK. 

First photos here.

To help prospective sailmakers with estimating:

I ordered 30 linear metres of cloth with a usable width of 1.65 metres, to make a sail with a projected area of 22 square metres. I have 8 linear metres of full-width cloth left over, with a pile of offcuts and wastage that amounts to 1 - 3 square metres. Making the assumption that 30 linear metres of cloth were actually supplied, 22 linear metres at 1.65 metres wide were needed to make a sail of 22 metres projected area - 65% extra! But that turns out to be a false assumption. Adding up the lengths of all the panels, I must have used at least 25 linear metres, with the tablings as part of the panels, and the pockets cut from the offcuts from the panels. I must have been supplied with 33 linear metres.

Adding up the areas of all the panels, including the seams and tablings but excluding the batten pockets, it comes to 27.2 square metres. The batten pockets amount to 4.8 square metres. So 32 square metres of cloth have been built into the sail, for a finished projected area of 22 square metres.* The seams, tablings, batten pockets, yard sleeve and the rounded edges on the top and bottom edges on the panels have added on something in the order of 10 square metres of cloth. 

I suppose the general point I'm making is this: make no assumptions, make no guesses. Draw out all the components of the sail you're going to need, and lay them out onto a drawing of the cloth, and add everything up.

* I remember doing a similar exercise for Tystie's fantail sail. Projected area of sail 54 square metres, actual area of finished sail including the roundings on top and bottom edges of the panels 71 square metres!
