We've all experimented with odd stuff from time to time, I'm no exception and still have several in the works. Being able to see a novice through without nurse-maiding them is the best way to learn, if painful at times. We all remember ourselves and our kids and some of us, our grandkids at this age and experence level and it's perfectly natural. What isn't are the assumptions Dsigned is making. As an example, how many cardboard boats have you built? How many kids (cardboard boat) have you helped to satisfy a class assignment? This forum, in just this particular venue alone, has nursed dozens though this classic classroom problem. Maybe you should try to keep up or at least contrubute.
Additionally, how many of your designs are currently being built by forum members, as well as others (non-members)? I know how many of mine are. How many boats have been completed by you or one of your clients, by your hand or another's pen? It pretty darn easy to complain about the old curmudgeons, after breezing through a few threads you might have some interest in, while another entirely to have spend many years participating in helping, advancing builds, techniques and general expertise. From what I've seen of Dsigned's participation, he does seem to find "all sailboat designs", "all designers", "all off shore designs" etc. encompassed with some indefensible grandiose, blanket statement, that's easily disproven. On the other hand, we (the forum) have America's Cup winners and world recognized NA's and designers that actively help out here.
Lastly, the PuddleDuck is a concrete mixing tub rigged up to sail. It doesn't do this well as you might imagine, though a few have managed to use superior skills to get them scooting along (hi Mik). Yep, they're individualized, but this is what you do to a pig, put lipstick on it, so it can be tolerated to some degree. It's likely the most hideous of all first builds and no one goes back, to build a second after they wear out the first. In it's defense, even the instructions for the various PDR's use appropriate techniques and materials, though faux gun ports are a bit much.
