there is not really any blog. Some updates on facebook, forums etc. But they closest are most detailed place (technically is) weldingweb under project and pictures. (warning its quite long) Agree that FB is a mess. We consider getting our own webpage, but welding have higher priority sofar.
Boat is in norway after sailing norway-brazil- norway last year. We see we need more modifcation. like deckhouse and engine plus get rid of small stuff who eats sails and ropes. (long list here) Building up a workshop in downtown oslo close to the boat.
re Lead: we have between 6 and 7 tonns of lead in keel. It had to be moved back when boat hit the water. Now it seems quite balanced but maybe a little heavy.
Will not need to alter prop or keel aperture. its space for 610 mm prop. engine have to be moved forward through bulkhead or up, depends whats easiest. Today the engine is horizontal, so if we keep that system we need move it forward to add space for longer/wider engine.
Hull has been working perfectly sofar. I cant point at anything there. Ofcourse she is a slow boat. weight 24 tonns, long keel etc. Might make her faster by getting more sails and higher masts but she has been sailing in areas with little wind and also from not the best angle gaff-rig wise. (on starboard or port tack for weeks up atlantic) Downwind she will work better, but who wants to sail just downwind?
