It is determined that the distances between the struts are too far for the strength of the canvas, so Spencer and Theo build styrofoam bulkheads to act as non-structural canvas supports.

Gabe is working on a foot-pedal steering mechanism for the outside team’s boat. It’s complicated because there is no floor in the boat yet.

As part of an ongoing theme, Jiro and Leo collaborate on this daily picture of “The Drill Master”.

The outdoor team has decided to use a beautiful pea-green for their outrigger. Turns out Maxine has a knack for applying wax.

To allow for changes to the rudder mounts on the catamaran, Theo must build plywood bulkheads to attach the canvas skin to (instead of the rudder mounts). It’s a tough drilling operation because round notches to accommodate the PVC tubes must be drilled out of each corner of a triangle, so he’s using clamps liberally. Leo is just hanging around the drill press to look cool.

Among the debris of boat construction, a beautiful wildflower has blossomed.

Spencer is striving for a perfect, wrinkle-free, wrapping of the last pontoon of the catamaran.

Theo hammers the new plywood bulkheads into place.

You know it’s a busy building day when all the major power-tools are on the deck before lunch. Maxine at the chop-saw, Theo at the drill-press, and Hanna on the jigsaw - Spencer waiting his turn.

Everyone agrees that Theo and Hanna manage to lay down the best wax job ever.

The sun comes out while Maxine and Gabe develop a hanging seat in the big outrigger. As you might imagine, it’s a bit tricky to put a seat in a boat with canvas sides.

The teams have mutually agreed that they all need paddles in case their propulsion systems fail. Maxine and Leo make a couple of paddle blades before going in search of suitable handles.

Spencer and Isaac take one of the waxed catamaran pods back to the studio for rudder work.

Note the piece of blue high-pressure gas pipe on the ground.

Everyone needs a break from boat building so we all go outside to see what fun can be had during the break in the fog. We spy the blue gas-pipe and note how well it slides on the pine needles…

Spencer grabs nine feet of it to make a stand-up sled.

Leo and Isaac discuss the relative merits of wood and pipe. Like skiers and snowboarders, they fail to understand each other.

Isaac shows us how it’s done west-bay style.

Maxine sprints down the hill with a wide-eyed Theo in tow. Hanna is more dignified than all that.

No handles, no brakes, no steering, and just too much fun. Theo zooms past as Maxine pours on the speed.

It’s the only thing anyone yells beside “whoa!” or “aaaahhhh!” on the downhill sled ride. Theo is not pulling as hard as Maxine did, so Leo is yelling “Faster, faster!”

Maxine, exhausted from pulling the sled, takes a little nap on the porch, nestled among the pliers, paddle wheels, lashing twine.

Spencer has invented a new toy which tickles your hand. Sure enough it elicits giggles from Maxine as well as everyone else daring enough to try it.

After his first prototype failed to pass inspection, Gabe digs in and starts work on a new design that is larger, simpler, and has more throw. Jacob helps him hold the stapler down.

The big outrigger requires a new technique for stretching the canvas skin tight, since passengers must be able to sit down inside the boat. A strong-line is run from bow to stern down both sides, then the pink canvas tensioning lines are tied to it, which creates some nice spiderwebby patterns inside the boat.

Tonight it’s chicken enchiladas, salad, and chips with guacamole - and of course, as much fruit as you can eat.
