What does the designs tell you?

29'er (sail 12,5m2)

It was my intention to find a flat bottom (2 or 3 chines) plywood sharpie, but so far I didn't find any typical example with 12-14m2 sail.

Perhaps the Windmill: http://www.windmillclass.org/faq.html

The question needs some focus. We have dinghies mentioned, then we are worrying about the southern ocean.

For a dinghy comparision, study the history of a development class such as the Moth or International 14.

For keelboats, there were the square meter classes.

Conditions and crew make a big difference. I read that the Cal 40 was slower around the buoys than later Cals, but faster to Hawaii because it was easier to helm. That made a difference in a long race, but not in a short one.

A hard chine skiff running pretty well is the old Fireball. Designed for plywood. Planning like crazy. Look for plans in the internet. It's an international class with a lot of gadgets hardware on. Do not be fooled use the hull and put the rigging you need. It may fulfill your requirements. .../

Fireball seemed a little bit odd. To include the Windmill wich looks more convensional...

First it says in the windmill presentation that it is overpowered with 100sq' wich is around 10m2. The fireball is also fast.

What would be the first (1) design change you would make to those dinghies to make them:

A) more safe /steady?

B) A + carry extra load (~300lbs)

I'm not sure where you get that. In the third paragraph, it refers to the sail area as 'moderate.' http://www.windmillclass.org/faq.html

Hej slomo igen...
Jag gissar att slomo här o morgan där är samma person.

I think that you need to define what it is that you are really looking for.
If you are the person I think you are you first said that you wanted a rowboat that can sail, now you are comparing your ideal mystery boat with planing dinghys.

You have to focus on what you want and why, and go from there.

When you seriously start learning about a subject like boat design you will realize that its quite a complex subject, and there aren't as many straight and simple answers as you would like.

A fast planing dingy will not make a good platform for a rowboat or beeing powered w an outboard. It is not meant o carry large loads either.

You cant build a fast, light, safe, heavy, loadcarrying dinghy cheaply that has a small sailarea. Its just not possible. You have to FOCUS on what you want and why and how to achieve it.

Please forgive me if I'm wrong in assuming that you and morgan.o is the same.

No, there is no reason why I should excuse you.

It's quite clear that your mission isn't of the kind sort and that you try to behave according to netiquette while your crusade still have the lowest possible intentions.

Netiquette is built on respect, und you don't accept that.

Actually it's a disgrace that your mess havn't been erased yet.

What on earth is the matter with you? Erik made a mistake in identifying you, but so what? He even asked for your forgiveness if he was wrong... But perhaps forgiveness isn't part of your kind of netiquette?
BTW: He was right in everything else he said!
