Today we travelled by ferry to Nantucket for a family vacation. The kids are out of school this week for spring break.

Today Nico and I viewed the Red Sox game against the Rangers from the NESN (New England Sports Network) luxury box courtesy of Chris Waddell. Chris, a five time Paralympian gold medalist will attempt to be the first paraplegic to summit Kilimanjaro. He will use a custom designed, lay flat, hand-cranked wheelchair for his attempt. Please visit his website to learn about this courageous mission. I shared what we learned from our Kilimajaro adventure and he enlightened me about baseball and the game we were watching. The Sox went down 5-0 before rallying late in the game with 6 unanswered runs to win the game. Nico did a little long lens photography from the front row of the balcony.

Today we joined the Gutwillig family for white water rafting on the Concord River. Normally it is quite tranquil but for a few weeks during the spring it is transformed into a Class 3-4 challenge by snow melt and heavy rains. I must admit that I was not expecting much excitement from the docile Concord but that changed after we shot our first rapids. On the third set Alex was ejected from the raft and we had to fish him out of the chilly water. On our second run of the day we got sideways against a large boulder and the raft flipped rather dramatically sending all of us and our guide into the water. Nico and I were trapped under the inverted raft as it continued down the rapids. I was able to breathe from the air pocket but Nico had to struggle mightily to get out from under. Kyle flew straight up in the air and landed feet first on some combination of the rest of us. He assumed a good rapid running position (feet pointed down stream and out of the water) but crashed into a submerged rock resulting in a nasty bruise on his thigh. Jeanine, not a big fan of the water in general, suffered a number of bumps and bruises but made it to shore safely (where she decided to remain for the rest of the afternoon). I lost my glasses ($800) and thought it was a small price to pay for such a thrilling experience. Later I discovered that my camera ($600) was entirely submerged inside the water tight bag I had purchased earlier in the day. Silly me, I had assumed the bag was meant to keep the water out rather than in. I did the math again and decided that we were lucky no one was seriously injured and that the other stuff really didn’t matter. Our guide told us it was the first time she had flipped in nine years of river rafting.

This morning I came down to breakfast and Jeanine greeted me with those 4 words I live for.
My computer isn’t working!
This is right up there with,
The dog ate your new soccer shoes!
The LCD monitor was dark and the CPU was on. Begin troubleshooting. Monitor or CPU? Monitor fails to display internal menu ruling out CPU. Close inspection of screen in bright sunlight reveals pixels present but backlighting is absent implicating either high voltage inverter or CCFL lamps. Disassemble monitor, locate inverter, power on, check for high voltage (absent), check for low voltage input (present) implicating inverter. Remove inverter, notice burn marks on back side of insulator, map burn marks to components, identifying switching transistors U1 and U3, check diode voltage drops, both are open implicating these two devices. Quick check on the Internet and they are available for three dollars a piece. With any luck I will salvage the monitor for $6 and 20 minutes of effort. Pictured here is the inverter board. Maya says it looks like a miniature city.

I decided to make the coaming for my kayak out of carbon fiber. So far this has been the most difficult part of construction. I used a layup of FCCFCCFCCF where F=fiberglass and C=carbon fiber. It took almost four hours to complete the task which involves building up one layer at a time and then waiting for the epoxy to stiffen before beginning the next layer.

Between Jeanine’s birthday yesterday and my soccer match this morning, I was not able to do much work on the kayak. We played Lexington, one of the reputedly stronger teams in our division and beat them in a strong 3-1 showing. I scored a nice header off a corner kick for the first goal. I did manage to cut out the cockpit opening and install the vertical coaming later in the evening.
