Re: Sarah 41

Beav, The frames when finished are 9mm ply plus the 19mm pine edging, therefore so are the stringer cutouts ie 28mm thick. When you fit the stringers into the cutouts after you have stood your frames onto the strongback, obviously the frames are narrower at the bow, and bend them around the frames, ...

Re: Sarah 41

Beav, The hull soles sit on the lower chine stringer which is 68 x 19. The most trafficed area of the boat is between frames 5 to 7, whis is your galley on one side and the nav station area in the other.

Re: Scarf vs. butt plate

the bridgedeck ply is step scarffed together, make sure to subtract the step scarfs in the overall length of the bridge deck. I just clamped a fence across the ply and used a router to route out the required 6mm depth, from memory my step scarfs were about a 100mm wide. Mine was 7 sheets long and th...

Re: Sarah 41

The Pure Majek build diary is a fantastic reference to have, most of the builders I know have themselves a copy, I believe I have the first one printed.
Great electrical info. Spent a few days on the boat as well, It is my cell phone screen saver.

Re: Sarah 41

The Ply should never be exposed to water as it is encapsulated in glass and epoxy that is why you can use the okhume ply. Peter Snell told me that once you have completed the hulls it is impossible to then build any significant lightness into the boat. I have saved over 200kg ,(450LBS) by using the ...

Re: Vertical Strip Planking

There is a video on the net of a guy building a Farrier Tri using foam and it is on timelapse. I would think that the fairing the outer and inner faces would drive me crazy with all the compound curves. Unles you intend to build a false inner liner. Surely a flat panel design would be more efficient...

Re: Sarah 41

BTW I used Gaboon Ply for my build, which is Okoume Ply in the states. My sheets where 9kg a 9mm sheet, Kakoda Ply (not sure if available in the USA) is a bit lighter. Both have aa faces and marine bond glue, Check with you suppliers with regards to weight. You do not necessarily need to use "Marine...
