It looks like a very clean wake to me.

The CM developed plywood 65 foot catamaran entered service on Lake Victoria, in Africa.  That’s 27.5 knots.

The migration to Win 10 and Office 16 is mostly there on the new laptop.  Will be the office web machine and portable CADD now.
So far easier than I feared. It has however taken an hour and Bing for me to get into the blog here.  Matthew helped with suggestions.

It could be bumpy a few times here. Leaping from XP to Win 10

Amazing rapid construction by Albert, the Thain Boatyard shop lead. Not everyone might understand that this female mold is developed plywood, with minimal fairing. I had been doing this with CM before, but Albert simplified it even better.
He CNC cut out the stations, then tortured a single layer of 4mm ply into it.
That is huge time savings. It becomes a big 3 D batten.
The other shape is the strip planked deck mold. It had to be done the old ways.  It looks like to could also be a party barge mold.

50′. Foam glass hulls. Ply/core/ply cabin showing bright wood inside. Carbon added to plywood to save weight where reasonable.
A pair of 140 hp outboards to give 20 plus knots.
Lake Chelan is right up there with Lake Tahoe as a deep, scenic, crystal clear lake.

I got back from out of country to a truckload of rush projects. This blog fell behind.
Besides getting autocad files of hull lines to Owen, a new 50′ ferry for Lake Chelan in Washington here, a 79′ charter cat in Mexico, finishing up the new 79′ Sierra Cloud for Lake Tahoe, a new wingmast design, more on the 45 cat, and several little ones.

I did see that the heavily marketed Rapido 60 trimaran was only in the middle of the E-glass fleet in the ARC race when it lost it’s mast. I understand that no other masts were lost.
I also saw that Russell Brown took great exception on SA to my doing commentary on designs.
There should be some quiet here during the holidays where I can catch up.
Also, I keep the hot shot workstation off of the net. Just to be sure. My web machine is an ancient Pent4 using XP. Anymore it slams up to 100% CPU use as soon as I turn it on, and stays there. Everything is a big hourglass.
Nothing I’ve tried is able to cure that. It seems the antivirus software takes most of the bandwidth. So I bought a new computer. The handoff of programs, database, email and varous peripherals may or may not be seamless.  I will try.

Almost 1000 spam came in over the weekend. The online computer is choking on it, as well, the antivirus software keeps uploading new anti definitions. So, I may have to get back to some of you next week.
When Outlook crashes, it starts loading the whole lot from the beginning again.
I see a new web computer in my future. This one is pretty old. I do keep the workstation off line.
