I would be interested in reading the details of this - how much lower? And does the "Offshore" version have any other modifications?

Chris

I was thinking of lowering the ballast by 100mm, to make the draught about 800mm. This would mean adding some exra deadwood between ballast and hull. This assumes that the bilgeboards are retained. A fin keel could be fitted, with no bilgeboards, and then the draught could be as desired by the skipper - 1200mm?

another change I would make would be to replace Annie's bi-fold washboard with a single fold-down or slide-down washboard, raising the sill height; and then adding a sliding hatch and garage. I have a sketch design of a way of incorporating a rotating pramhood into this arrangement, but I have been unable to convince Annie of its merits. I would want a settee berth near the centreline, for cat-napping, but this is probably a matter of personal choice.

If you are glassing over it, you can gently press on the cloth being extremely careful not to deform the fillet, and then wet it out, again very gently.  Otherwise leave it until it's almost set before overcoating it with clear resin.  If that's going to be some time in the middle of the night, or you're doing some other job, then it's fine to go back and give it a light sanding before coating it.  If your fillet seems a bit rough, leave it to go hard, sand it and overcoat it.

I always put a coat of clear resin over the top of fillets (as the Bible recommends): it seals the fillet (in case of minor holes) and leaves a smooth, hard, shiny surface which stays clean.  Fillets of pure silica are often quite rough, even with the best of efforts and over time, dirt will lodge in them attracting mould which will be difficult to clean out.

How I wish I'd known exactly how it's done last year. (the results were ok, but) Thank you Annie for next time!

Dearest Annie

I've been following SibLim project with enormous interest. It is high time I posted something too.

I am absolutely thrilled that David's design strung all the right cords and of you went, all bells ringing! The speed at which you are progressing is dizzying. I cannot believe it. 

Thank you and David for keeping us so well posted and for yet another inspiration! It's wonderful to follow your (and many of ours) dreams unfolding.  I wished I was closer to NZ as I'd love to help with SibLim in making. I have been talking to boat builders in Croatia about building SibLim for me ... I will be in touch!

Meanwhile I will follow this forum very closely.  

Sending you tons of energy from the Adriatic

So good to hear from you.  I hope you're having heaps of fun back in the Adriatic - it must be good to be out of London.  I'm so pleased you regard our progress as dizzying: David has been grinding his teeth at my insistence on panelling bulkheads and wanting spaces that no-one is going to see to be as well finished as those on view.  No doubt this is a ridiculous attitude, but I want to know that all the boat is as well made and finished as I could achieve.

I am sure a SibLim would suit you very well: you're not tall and she would be a wonderful boat for general cruising.  David has an "Offshore" version, too, with the ballast lowered for ocean crossings, which you might prefer for next time you go round the Horn :-)
