I did stumble onto an old IBEX paper by JR on In-Field Repairs. Good one. I will find out if he has has a link or a word file of it.
One gem. Wet epoxy spills will fluoresce just like body fluids. Who knew. Grab that blacklight from behind the In-A-Gadda-Da-Vida album…

Design Book Status
I expect to get the proofs tomorrow. I do need to look as there have been so many changes. And wow have they gone up in printing cost! They do remind me that there are so many new pages….
Next Lake Victoria Catamaran Ferry
The guys are moving right along on the next KHSD 65 passenger ferry for Lake Victoria at Uganda. The shop is up in Arlington, WA.
Nick’s Launch
Nick Del Giorgio launched his KHSD 42 catamaran! Good stuff. He added a nice house on it to keep out of the sun.

Conservation Remix
Back on the 10th.
A lot of what multihulls are about is doing much more with much less. Along that line find a very interesting event coming this June 2nd at University of Washington. http://conservationremix.org/
Actually I’m surprised they didn’t include multihulls, (and maybe even local designers who are alums?)
To register, visit: http://engage.washington.edu/site/R?i=UZKdoK5mX3D1Stjswp9tiA
Look at some of the topics:
Pamela Ronald
Genetically Modified Conservation
Pamela Ronald wants to use modern genetic techniques to create a new brand of
agriculture that slashes insecticide use, increases yield, and thrives in a warmer,
wetter world.
Yoram Bauman
A More Verdant Tax Code
Yoram Bauman, a University of Washington economist and standup comedian, thinks
we’ve got the tax system backwards. We tax things we want more of (i.e. paychecks),
not things we want less of (i.e. pollution). Doing the opposite would yield cleaner
air and
flusher bank accounts.
John Edel
Indoor Urban Agriculture
John Edel, a Chicago entrepreneur, has transformed an abandoned meatpacking facility
into the nation’s first vertical farm. His goal is to bring large-scale,
net-zero-waste food production right into the middle of the city.
Joe Roman
Invasive Species Cuisine
Joe Roman, a biologist at University of Vermont, believes we can best tackle
outbreaks of non-native species by serving them up-for dinner.
David Allen
What is a Smart Building?
David Allen, executive vice president of the engineering, construction and energy
services firm, McKinstry, designs super-efficient buildings that “know” when to
consume, shift, store-and even generate their own energy.
Brent Constantz
Cement that Absorbs Carbon Dioxide
Brent Constantz, an entrepreneurial marine geologist from Stanford, believes that by
mimicking the way marine organisms create shells, he can manufacture concrete in a
way that traps carbon rather than spews it.
Susan Mac Cormac
A New Twist on Capitalism
Susan Mac Cormac, a corporate lawyer with Morrison & Foerster, helped launch a novel
corporate form a kind of hybrid between a nonprofit and a corporation that has the
flexibility to pursue both profits and stewardship.
Sherri Ritter
Nature Inspired Engineering
Sherry Ritter, research and education specialist with the Biomimicry 3.8 Institute,
teams biologists with engineers, architects, designers, chemists, and others to
design super-efficient, ecofriendly technology based on nature’s time-tested
strategies.
the New Design Book
I put so much time into this new new book. So many upgrades and additions. It will be wild. The new cover.
The New Design Book is Done
Finally. The major upgrade to the Design Book, 2012 is done. It has been a big deal. It will go to the printers on May 11 or soonest work day after the 10th. I appreciate everybody’s patience.
My goal also is to have a CD version with the print design book. It will be in color and have the hot hyperlinks. I am using Pagemaker as I just didn’t have the 2 hours it usually takes to get my Indesign permissions taken care of on the new laptop hard drive. So I will have to run all the Pagemaker files through Indesign when I get back to hot up the hyperlinks.
Thanks again.
New Rowing Trimaran
You might recall that my Formula 40 catamaran hull lines held the world record for fastest rowing across the Atlantic last year. For a day. I did not know about the rest of the design, and a lot was wrong. I insisted on being fully involved with the next boat. Crew of 9. Here it is.
Rower 60 Trimaran
Features:
Main hull has L/B of 21:1. Displacement of 4848 lbs. Hull speed is 11 knots. At hull speed it takes under 6 hp to move at that speed. At that speed there is 265 lbs of form drag and 125 lbs of friction drag. Draft is only 12” so change in depth over the trip should not change much, keeping waterline long.
X bow allows less hull area, reduced windage and significantly less wave pitching. See video at http://www.militaryphotos.net/forums/showthread.php?152989-Xbow-Sea-Axe-A-future-in-the-Military-Design.
Next year everybody will have these bows. Flare is high enough above waterline that it should not increase pitching.
Total main hull max height is 6.5’. I say that the governing load will be a wave on each end and the middle in the air. The flare also helps restrain buckling.
Curved openings are much stronger. Upwind I would cover openings with Eisenglass or thin acrylic like man-powered craft record holders do.
Top will have solar panels and flush hatches as needed.
Amas are just under 17’ long and 1000 lbs displacement reserve. I see greatest load being pushed sideways 20’ by a wave. Location aft helps minimize pitching again as it spreads out the centers of buoyancy.
I assume beam should be completely rigid, like in bicycle racing where flexing frame is seen to absorb power.
I see this as having every possible thing done right. I don’t know if 5’ tall above waterline is too much. It does give more beam depth.

Back and gone again
I’m back. I’m gone again tomorrow. I thought I could get out of it, but no. Back on the 10th. I might have email. Any shopping cart orders cannot be filled until I return.
Lightning and Sailboats
This very interesting article on lightning was noted on the multihull forum. See http://edis.ifas.ufl.edu/sg071
