thanks for all the comment here but i have the feeling that we drift of my question

is must be the problem of translation,

i am german and english is not my first language. so i probably confuse people how i as my question...!!????

i am not questioning the motivation or the ability of my  boat building friends here.

my question is the ability to resurge informations...

i look at this page everyday and experience that subjects / question get repeated.

that my point.

cheers hans

one problem i see is that no one points to the information. I have gone through this thing and the questions i have asked have for the most part been unanswered. for the most part i dont think most folks actually spend much time here and so its sort of talking to oneself

I'm revisiting this thread because I'm in the process of completing my Hitia 17 build and going through my notes.  It occurs to me that every interest group on this forum, specific to a boat design, should have a single thread listing Errors and Omissions for a particular set of plans.  I'll start the one for the Hitia 17 and it will be called "Hitia 17, Errors, Omissions, and other Stuff."

Let me partially expand on this theme-

An Error is just that, usually a measurement that is just wrong.  It may be due to an English to metric conversion, a metric to English conversion, or just the wrong measurement.  The Hitia 17 plans give the wrong measurement for the width of the rear decks.  No knowing this will cost you time and one sheet of plywood.

An Omission is something that should be on the plans and isn't.  It may be a piece of hardware that is shown on the plan but isn't sized or listed in the materials list.  It may be a wooden component that isn't dimensioned.

This one will be a little more complicated to explain- There Be Dragons (TBD).  This could be an error, but there is no way to tell if your sample size is only a single boat.  On both my Hitia 17 hulls, I have the same two discrepancies on both hulls at bulkhead #2.  Without building another pair, I've got no way of knowing whether it's something I did, or an actual error in the bulkhead dimensions.  So the point is "I got a different result than I expected, you might want to pay extra attention here."

The last is Hints.  It could be as simple as "I must be an idiot, because I did what the plans said and it didn't work, so I ended up doing this instead."  Or it may fall into the category of "I know this is what the plans say to do, but I think it's a bad idea, so I did this instead."

This isn't going to make the boat you just built any better, but it will help the next person who builds from a copy of these plans.  Additionally, some of the lessons learned will translate into future, as in larger, projects.
