      Abbreviated rules   07/28/2017

      Underdawg did an excellent job of explaining the rules.  Here's the simplified version: Don't insinuate Pedo.  Warning and or timeout for a first offense.  PermaFlick for any subsequent offenses Don't out members.  See above for penalties.  Caveat:  if you have ever used your own real name or personal information here on the forums since, like, ever - it doesn't count and you are fair game. If you see spam posts, report it to the mods.  We do not hang out in every thread 24/7 If you see any of the above, report it to the mods by hitting the Report button in the offending post.   We do not take action for foul language, off-subject content, or abusive behavior unless it escalates to persistent stalking.  There may be times that we might warn someone or flick someone for something particularly egregious.  There is no standard, we will know it when we see it.  If you continually report things that do not fall into rules #1 or 2 above, you may very well get a timeout yourself for annoying the Mods with repeated whining.  Use your best judgement. Warnings, timeouts, suspensions and flicks are arbitrary and capricious.  Deal with it.  Welcome to anarchy.   If you are a newbie, there are unwritten rules to adhere to.  They will be explained to you soon enough.

    more like a laurie davidson 72'er, Bob
  2. Long/Short lived sailboat models?

    True, but only 2 built, so few people outside PNW would know about them. Plus, one of the criteria is it has to be in one of Bob's SAILING DESIGN books Kodiak (ex-Midsummer) is the other D29 and is still kicking butt in Van. Dibley: I thought the stock foil package was very good although apparently the boats area bit of a bear offwind when the breeze is up. I suspect that may be due to the rudder being on the small side (for the size of the sail plan) and quite far forward (see photo in post #54), so I can see replacing that. But I can't figure out why the blended bulb keel (more of an upside-down keel) was replaced with a T-Keel since the boat is plenty stiff in a breeze. Kind of curious how it has all worked out. is it an improvement, or too early to tell? Hi 12-metreGood point on the number built. I should read the whole thread. Not sure what you mean with the Madam Pele and keel package. It is a big improvement from the old keel package, for sure. Sounds like Kodiak and Madam Pele better line up together My feeling was that being such a beamy boat, the D29 would rely more on form stability so lowering the VCG wouldn't help so much. The actual lifting surface looks fairly similar. I guess I overestimated the amount of drag and pitching moment the bigger bulb would add. Old and new keel photos below. Yes, would be interesting to have Kodiak and Madam Pele line up together again. IIRC they went head to head at RTC a couple of years ago Midsummer (Kodiak) finishing second and Madam Pele third Madame pele was 3rd, Midsummer 4th. How about the ross 930?

    There are definitely similarities in the keel profile between the FT10 and the new one on Kokopele On a side note, I finally found some half decent tphotos of the engine well setup on the FT10. How did you get that SOCA type system to work? I mean for vertical clearance. Obviously a short shaft outboad is used, but still. Another Dash owner in WA built that sort of a system but said he killed 2 engines within a couple of years due to flooding. He speculated it was because the hull depth of the Dash is greater than a M32, but I would hazard a guess the FT10 and Dash have similar hull depths although I'm not certain. If you guys are talking about madame pele (kokopele) keel, we just took the original laurie keel off and are in the process of putting on a new dibley design Is the new Dibley design the one in the photo I included in post # 343 or is that just a keel that got thrown into the mix in the Facebook page I pulled it from. I'm not surprised it would be a Dibley since he and LD are pretty tight as I understand it and LD I think is retired. yes that is a pic of the new keel

    on the davidson 29, there are 3 or 4 very long CL bolts attaching the cast bronze T flange to the cast lead fin. there are also 6 bolts attaching bronze flange to 3 of the keel floors. The keel transitions from bronze to lead at the point where the lead is strong enough to handle loads from only CL bolts You seem fairly intimate with the details on this SJ, were you involve in the recent refit from a blended bulb to a T-Keel? I know the owner had discussed this on a SA forum a few years ago. Not sure why the keel refit was necessary since they are pretty powerful boats to begin with and have gobs of sail area. These are still my all time favourite Racer/Cruiser design, It's a shame more weren't built (and yes, I know the story behind that, or a least I believe I do). Found some photos of the refit on the internet. The hull in the cut out area looks to be in fine shape for a 25 year old woody. yea thats me on the bow. i did a bunch of work on midsummer/kodiak just before it went to vancouver. i dont like the title of this thread

    peel ply leaves a finish that is much easier to sand after curing (secondary bonding+ prepping for paint) this is cool to see the boat school taking on this project
