Bio Composite Materials

in my Automotive Design/Production magazine I read about a new composite being by the University of Portsmouth in UK. They are using a date palm fiber biomass for things like bumpers and liners. The products are reported to have better tensile strength and better low velocity impact strength.
Date palm fiber polycaprolactone PCL bio-composite is completely biodegradable and recyclable…”

I get a bending strength of about 50,000 psi which is impressive.

52′ Tri Hound

I was shown this 52 Mcconaghy trimaran with an interesting hound arrangement. Composite rigging guru John Fanta advises against any hidden composite rigging arrangements.

It also had an oddly large masthead plate and an oddly small and badly chewed up exit for something there in the picture foreground.

Chaak Pic Again

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.

On the Way to the NEMA Event

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.
