Chaak recently popped up on the Classical Sailing Multihull page. After she ran hard on the beach, destroying the original amas, I was asked to design new amas and beams for Chaak. ’85 maybe? They have proven to be tough. It did a run to Hawaii and back. It was campaigned harder than most PNW boats at that time. I recall Tim mentioning one time when the route back from Hawaii was by way of Alaska. Tim started to realize that when the shadow parted from the boat every few waves, it meant they were airborne.
USCG aircraft above asked if then needed help. “Nope”.
I recall that there was a Constant Camber 44 designed that was supposed to beat Chaak in racing. In fact it was nicknamed “Chaakduster”. Was not even close.
I was sent this great picture of Pipe 3.
I understand that back when it was Faamu Sami, Salty used to singlehand it everywhere while out cruising. Nice.
It was a great time presenting my designs that night at NEMA. Thanks again Andrew. And then the next day I got to climb all over and inside my 46′ trimaran design Pipe 3. Bob Gleason let us have the amazing time. Thank you Bob.
I rode down to the event with former crew and amazing sailor David Osteen. As we were leaving a marina, he spotted an ama sandwiched up on the hard in between a dozen varied craft.
We got out for a closer look. It was my 46 performance tri design Pipe 3 (formerly Faamu Sami). It was the first time I have seen the boat.
I was fortunate enough to be invited to present my designs to the New England Multihull Association, (NEMA) in Newport RI.
My PowerPoint had 200 slides and nobody fell asleep. Cool. I met some great people there.
Back to it’s first home after a lap around the world.
Nice note from the new owner, Paul.

When Kurt Hughes designed this boat he really got it right. Tacking strongly into big Western Australia seas and wind. We are comfy and dry and pointing high biggest problem is trying to slow down. Thanks Kurt”
A nice note from Andrew. I hope my builders in the area can show up and talk about their projects.
“ANNUAL DINNER FEBRUARY 2, 2019
Kurt Hughes, Multihull Designer
Kurt Hughes, a prominent multihull designer and builder based in Seattle, Washington, will be our annual dinner speaker at the Cambria Newport Atlantic Hotel, February 2, 2019.
Kurt has a long list of significant multihull designs that are scattered around the globe, including trimarans, catamarans, and proas, both sail and motor powered. He has also lectured extensively on composite construction techniques and multihull design. He’s built three substantial trimarans – 26, 32, and 40 feet—and a 23 foot proa. And he’s applied composite boat building skills to the construction of a “lunar lander,” a “retrofuturist tiny house being built using advanced boatbuilding methods.”
Kurt will talk about the history, development and construction of his designs and take your questions about what works on the water and in the construction process.
We will also have our seasonal trophy awards, good food, a cash bar, and we expect some North Sails swag will be available. You can register at the hotel at https://www.cambrianewport.com/en-us, or call 1 401-236-2020. The hotel is giving NEMA members a special $99.00 room rate on Feb. 2, so you can check in and enjoy yourself without worrying about the drive home Saturday night. Register for the annual dinner through the nemasail.org website. We look forward to the annual gathering, some tall stories about the 2018 season, and seeing friends new and old.
Andrew L. Houlding ”
They have an amazingly luscious newsletter. . http://www.nemasail.org/pdf/NEMA%20Newsletter%20DEC%202018LR.pdf
And in the group photo a ways down, what a crowd of multihull celebrities. I will be so honored to be talking to them.
Is This Catamaran Missing?
By John Arndt | December 17, 2018 | Sea of Cortez, Mexico | 0
Former Latitude 38 editor LaDonna Bubak just alerted us to a Cruisers Forum note that cruiser Bob Smith, of the home-built 44-ft catamaran Pantera, hasn’t been heard from in three months. His daughter, Natalie, has become concerned. Natalie reports that Bob has been living aboard in Mexico for the past 10 years. He typically remains in touch on a regular basis. Brad of the SV Perspective reports seeing him on October 19 on the Bay of Los Angeles in the Sea of Cortez with all well. Pantera is an active, well-known cruising cat along the Mexican coast, and a vet of the 2006 Baja Ha-Ha. We just want to help put Natalie’s concerns to rest.
Bob was in my office a dozen times as we did the design. At the dawn of CADD. Hope he is ok.
Found this nice pic of an early, maybe the first, KHSD 45 catamaran. How many laps across the Pacific has this cat done? 2? 10? I have no idea, but it has been dispensing fun for decades. Pic thanks to Richard Spindler.
While at Fish Expo in Seattle.
The Suzuki 140 hp outboards for the lake Chelan Ferry.
Looks like it should get 23 knots fully loaded.
Busy day today. Unfolded the chine panels for the 30′ catamaran workboat. Rhino 6.
Used to be I would just plot out the patterns. However, my nearly new Canon plotter that cost about half the price of a Honda Civic quit and they tell me it will be expensive. So for now I dimension the flat patterns.
Leaving HP was probably a mistake.
The second note from Kevin.
Here’s the results with the pulley changes. I will call shortly to discuss.
Installed 18 tooth pulley on QT10 (port), and two 20 tooth pulleys on QT20 (stbd).
QT20 display always shows “Key on” regardless of position, but doesn’t show “hours”.
QT10 display doesn’t show “key” at all but does show “99 hours”
Boat is still very light with no water or equipment etc aboard. Bottom clean.
Running perpendicular to a 14knt breeze in flat water.
Port QT10 running alone achieved 139amps, 1460rpm on power setting 100, going 5.6knts
Starboard QT20 running alone achieved 341amps,1844rpm on power setting 76, going 8.2knts
With both motors running: port got 152amps at 1700rpm, starboard got 353amps at 1875rpm with a boat speed of 8.7knts
Running port only at 100amps achieves 5.5knt
“ Starboard “ “ “ 5.8knts
Running one motor at 50amps gets 4.5 kits
2motors at 50amps each gets 5.5
Running both at 100amps each gets 7knts and when running into the 14knt breeze that was reduced to 6knts.
Reduce pulleys more or re-prop?
I took on the job of building a set of hulls for Kurts 28’ power cat design which we stretched to 31’ by adding about 2.5 inches to every station. We upped the stringer size by 30% and glassed with 8oz rather than 6oz but otherwise stuck with the plan and laminate schedule. We used multiple layers of 8 and 10oz to make up biax tapes, i find it makes for easier fairing and allows for tapering the buildup. We did a half-way-to-yacht quality fairing job, primed with 545 and installed cleats, hatches, fuel tanks, and fuel fills. There will be lightweight 25 hp engines mounted on rear transoms. We finished both hulls and shipped to the owner in maine, who is going to build the cross arms and center cockpit over the winter. I really can’t recommend committing to building a boat over the summer in sarasota, florida in a non-airconditioned space, but, in the spirit of running a marathon, and other ridiculously painful ways to enjoy yourself, we did it. Total build time, including purchasing, hardware, and mounting on a trailer for shipment, was in the neighborhood of a thousand hours. LOTS of pictures after the break-
