"Hi Ralf, have you had a chance to test your drogue configuration? Also what kind of backing did you do on the deck where the drogue plate is attached? Thanks, oh and I love the round portlights/portholes I think I may have to do the same! :) "

"Well you'll have a huge ammount of air locked up in there under the sun and the stars. That air will expand and contract every day, that means water INSIDE your beam that cannot get out. The designer specifies a vent hole with a breather tube…"

"Just curious if anyone has any follow up on this? Would be interested to know if you have had any issues or wear and tear on your beams from either having drain holes in the end caps or having them sealed. Been a few years since it was discussed, so…"

"+ one avoiding making a 10cm too long AFT beam. Thanks Ralph. A see a simple dashed line, and a length, in web draw to symbolize this shorter beam (but nothing in floor draw), and no more explanation is given. I suppose that the last vertical web…"

The star path, the succession of rising or setting guiding stars down which one steers, was known as the avei`a by the Tahitians... .... this is analogus to the kaveinga of the Tongans and the kavenga of Tikopia...

This is a succession of stars toward which the bow of the conoe is pointed. Each is used as a guide when it is low in the heaven; as it rises up overhead it is discarded and the course is reset by the next one in the series. One after another these stars rise till dawn...

Hello, Ralf,
You are doing a very nice boat. I like your turn up/down system, Very ease.

Just looked at all your pics and it sure looks great.  We are planning to paint our waterline on Peace just the way you have yours.  It looks right.  The way you turn the hulls and the little cart that will fit under the keels are clever too.  Hats off!   Ann and Nev

Nev was looking at the way you tension your webbing and he is highly impressed with that clever and simple method.  Me too.
