If you can design a triangular section that is lighter and carries the design loads more efficiently than the altenatives then that is the best shape for the...

Nothing wrong with triangular beams. We will be using them on the Elementarry's with carbon rods in the corners and foam webs. The main reason for using them...
I thought the main point of tacking down wind was to increase the swept area. With a kite shouldn't you be able to increase the swept area without taking the...
So did I, yet the windsurfers still sail the angles dead down wind. Dave is on this list, and may have some input. This is high on my list of things to ...

A pultruded carbon rod at each edge would handle the loads admirably. Fill the area between the rods with foam and it would be very strong indeed Attaching...
G'day, Beams will be V The lower rod needs to line up with the bulkhead that supports the mast, plus it needs to deflect water downward in both directions....
G'day, Interesting to see how you telescope these beam. A bit of graphite in the topcoat of the internal radii? Robert ... that supports the mast, plus it...
Hi Rob & al Just a thought. Some time ago you posted description and photos of the techniques you used to build a carbon fibre mast for Visionarry (IIRC). ...
Hi JIm, We are using some of the ideas from the strip planked carbon mast. The corner carbon rods are vacuumed in a mould the same way we made the mast strips....
Hi Robert, The male and female beams will have a couple of bands of built up resin/graphite applied where they overlap when extended. This will give plenty of...
Thanks for the update Michele The standard of finish on the painted hulls looks great. Beautiful smooth lines and clean reflections are a sure sign of great...
G'day, You ain't the only one looking forward to the launchings! If the boats sail as well as they look, we are in for some busy times. Arripiado was going...
Interesting that a single word is used in Portuguese for what takes English a whole sentence. I wonder what other simplifications we could use. I'm told the...

G'day Other contenders could be 'Ford' or 'George' both being a Harry's son, but Watson would definitely have been my preference. We'll be heading up the North...
Robert, Good to see you again. Would you let me know your email address, I have a drawing for you? Your return address bounces. Mark ************************* ...
Mark and Michelle, We really enjoyed our time there. Carole now seems OK with the extended Harry rather than the Visionarry. She'd like to be sailing before...
Hey Mark - We'll be wandering down Bello way this weekend and would like to crawl around Harry. Could you check with Bain to see if this is OK and give us a...
Hi Darrell, Give me a call when you are coming and I'll arrange to meet you at the shed. Mark ************************* Mark Stephens www.harryproa.com ...
Hello Rob - Had a look at Bains job, He's starting to smile and look pleased with himself and the results and so he should. The end is in sight. There's heaps...
I didn't think that the lw hull was that heavy. When I saw it , it was still at the stage wherre two people could lift it up with relative ease. I guess...
G'day, Glad you like the boat. I was pretty impressed myself. Harry ww hull bare: 350kg, lw hull bare without bows, bulkheads and sockets: 135kg. Finished...
Is everyone too busy sailing/building/working to catch the Harry group up on life, the universe, and everything? Peace, Mitch watching the frost on the ports...
Me thinks Rob is too busy. Still waiting on funding status for my wingsail for the elementary. Rob intends to finger point the fab, so mostly I am out of the...
