Email Down

My email is a mess just now. Outlook was getting its folder too full so I tried to start another one. It would not. Maybe Outlook 2000 only takes a few folders. I tried a workaround to ship the files to another folder. It took all day and only sent half of them. The result with each folder half full crippled both of them.

My Gmail will no longer recognize my password on the computer, but will on the smart phone. Am going to have to do something major and soon.

I do have the squirrel mail on the laptop so will use that for this week and next at IBEX.

Ocean Navigator

Recall I was sent pictures of what was stated to have been one of my cats. The revisons looked very dangerous to me and I had not authorized them.

I got this from someone going by the name Ocean Navigator. I  say what I see. To me it looked like a rescue waiting to happen. I wanted no mistaking that I was responsible for those revisions.  Windows are not to be taken casually.  Kelsall had one blown out in the last year or two resulting in the cat being lost.

And if I may, my window design never was intended for vertical windows.  You may not know that the wave forces are much higher on vertical windows.  I also did not design minimal framing.  Mine has much more beef.  And I can see your companionway down into the hull.  There is no 6″ coaming there.   I just report what I see.  So who are you anyway?  And if that is not how it will finally be built, say so and I will apologise.  The house looks pretty finished to me.  You don’t need a war, you need advise on making this seaworthy.

You take some random pictures of my UNFINISHED boat, put them up on your blog and proceed to trash it?!?!  WTF is that?

My boat was painted and buttoned up for weather so it could be moved (via the intracoastal waterway) to another location for another year of work on it. 

I used your fucking window specs from the plans.  It’s all foam/glass.  It has fucking combings everywhere (as well as drains).

Unbelievable.  Why in hell would you start a war with someone who is trying to complete one of your boats?

Don’t even think about naming me on your blog or I’ll get attorneys involved for a defamation of character suit.  

More VHB Tape

I had this article on VHB here almost a year ago. I did use some 200 lineal feet of VHB tape on the lunar lander dome windows.  http://multihullblog.com/?s=vhb

The lunar lander windows have been there for 9 months now, in up to 100 mph winds.    Recently one panel blew off in much less wind.  I contacted 3M to see what could possibly have happened.  All the other panels seem to be well stuck.

I do see that someone else had a problem too.  I understand it was the orange boat.  http://www.boatdesign.net/forums/boat-building/urgent-window-advice-needed-leaking-falling-off-53609.html And I do see he used polycarbonate, which will UV craze in in few months. Acrylic lasts longer.

This is what I learned from Jim Burger at 3M. 

After the cover comes off the panel, wash both it and the substrate with denatured alcohol.  There is no harm in sanding lightly on the contact surfaces also.  Then apply the 3M 94 primer to both contact surfaces.  Place the panels.  Finally come over the edges or corners with caulk sealant.  I used the System 3 two part poly sealant.

I did not sand mine.  I did not do the alcohol wash.  I only put primer on the substrate, not the acrylic.  I am guessing orange cat skipped some of the same.  I will do all the steps when I replace my rogue panel.

Why This Blog Has Been Neglected (2)

This 75′ catamaran model was also on a rush order. For carrying passengers off of cruise ships in Belieze. Was just a big chunk of boat to carry 275 passengers.

The model was for taking off ortho drawings and areas only. Owner was ready to start building immediately. After agreeing to contract, the owner said he could not pay for the plans. I had to agree to accept half fee.   I’m guessing a unit like this will bring in over $20K a day.  No, I don’t do half fee.  Wasted a couple weeks on drawings and spreadsheets.
