    We own a small classic yacht - a gaff sloop - which is excellent for day use & racing also. Cherub gets lots of use.

    I enjoy fishing & used to surf a lot. These days I'm a family man but we sail together.

  1. Hi Steve Yes, Cliff was a gifted amateur designer. I hope to be smelling the odd sweet scent of freshly cut Huon this weekend.
  2. Thank you all, & especially Keith - fortunately I wasn't drinking anything when I read that. Vaddoc, thank you - & one note on what you said: most boats built here at that time were done on a tight budget, & very few have exotic fitouts etc. The connection with what you said is that the bows & sterns are usually plumb - vertical. You get maximum boat for your timber that way. The 'lift' #6 (not sure if there's a technical name) needed to be corrected, as the previous post. I did that & also dropped the piece, so two minor repairs. Below
  3. Hi Vaddoc, looking very good. How does the line of the lower batten compare to setting out the garboard & then the first planks? Is this carvel planked?
  4. I started to pencil on the mould locations on the timber lifts, to help when I do rough shaping, of whether the sanded shape is straight, convex or concave. I picked up an inconsistency in the drawings. It goes to the issue of which drawing do you give priority to when there's a discrepancy? In this case its pretty easy, fortunately. Also the fix should be pretty straightforward. On the plans, this line was used to cut the the lift #6, it is the highest of the full length pieces. The red arrow points to it. If you look at the transom, that line is pret
  5. Hi Rich I'll attach a photo below from when the Spray was in Sydney. The photo has quite good detail, I hope it's interesting if not actually useful. I believe he was given new sails here & these do look pretty good. As an aside, our sailing club has a "Captain Slocum Trophy Race", the connection is that a member of the club was thought to be the first person aboard the Spray in Sydney. When he was about 10 & was fishing with friends near the heads when an unknown boat came in. They rowed over & went aboard. I am friends with the son of that boy, the son is
  6. Hi Carl Sorry for the slow response - golly it's been a long time since I was here last. Yes, this boat has swing centreboard & it's just visible in the photo in post #29. I don't have the open boat book, so I'm not sure on the reference, but in this case (which is typical of a pre-1940 centreboarder) there would be a removable pin at the forward end of the centreboard case as a pivot. The front of the plate is usually straight & the aft edge curved. I have made some progress: purchased timber, scribed the cutting lines & cut them out. I was considering plan
  7. Hi Stephen I haven't been following for a few months - & it's a pleasure to see your finished model. It's ravishing. The use of marble for the base is beautiful & the case is clever & enlivens the entire effect. I've gained from following the build. Mark
  8. Hi Stephen I have a couple of comments, hopefully they might be useful. But they wouldn't affect the rigging so much as giving alternative ideas on how they might have worked with a simple rig that has limitations: Given what you say about the stability of these vessels, it is a possibility that they did not gybe the sails. It is a tricky manoeuvre even in a little dinghy, let alone such a large sail area & a tender boat. It sounds like a possibility that for them, sailing meant heading downwind or within maybe 5-10º off the wind, & to make any angle to the wind
  9. Bravo Stephen, looks amazing. It would still be possible to use the new figures - they could be trimming a sheet.
  10. Hi Carl, yes there's a centreboard for certain - but a boat like Karoo would be pivoting & not lifting like the skiffs.
  11. Hi Vaddoc I was wondering what video was in store for us - it was the Brit! I've sailed a couple of times as main sheet hand on this boat, it was fun & hard work. But she actually does have keel timbers below the rabbet line, although not much at all. Otherwise there would be nothing for the bottom edge of the garboard to sit against. There's a deadwood aft, but again not large. I think Karoo probably had a more of both than Brittania, but maybe not much. If you see how the lines drawing of Karoo shows the lowest line parallel with the waterline, that was another clue - you wou
  12. Hi Vaddoc The clues are in the drawings. In the body plan, the detail below shows the curved line of the planking stopping at a horizontal line, not faired into a deadwood or keel. It's probably clearer in the plan view of the lines, below. At the bow the hull lines do not show the pointed or rounded shape of a stem, they lines stop where the planking would meet the stem. The lines resolve as a line perpendicular to the centreline, not the smooth resolved shape of a stem profile. Below you can see the planking & stem & keel clearly with h
  13. They are like 30' skiffs. On a reach they would be dynamite; it would be interesting to know if they could point well to windward.
