The new 24 hour record attempt!!!

24 hour human powered boat record:

This boat is going to be fiendishly fast!

First you have to check out this work of art that my buddy Manny from Rhomec Industries made for me:

It's the aluminum prop, spinner, bearing tube and fairing cones for the drive for the new 24 hour record attempt boat. VERY SWEET!

I want to keep the exact configuration of the drive unit proprietary for a little while, so I'm not posting any drawings of it here. I am aware of another group who has indicated to me that they plan on challenging my 174 km pedal boat record from last summer and I don't really want to give away any of our secrets just yet. I am not **repeat NOT** attempting to break my own 174 km pedal boat record - I am attempting to break Carter Johnson's 245 km kayaking record! I am aware that there is a big spread between 174 km and 245 km, and this boat that was designed by Rick Willoughby is capable of at least 245 km in 24 hours. If I am able to go farther than 245 km in 24 hours on a flat lake, then it will be the farthest any person has ever travelled in 24 hours on water under their own power.

Rick is helping with design and engineering direction, Manny from Rhomec is contributing his wicked machining skills to make the prop and drive unit parts, the right angle gear drive was donated by my buddy George and PedalTheOcean sponsor MitrPak, and my right hand man Ben is helping out in the shop. I'll have a cast of other friends helping with officiating, observing and other help like last year - it is TRULY a collaborative effort and I am VERY grateful for all of the support these friends are providing.

My original intention was to invite Carter Johnson to Calgary and stage a race and possibly a new world record by either Carter or I. I'm not sure that is going to work because lake conditions for a record need to be nearly perfect - very calm and flat water. That means I need to race on a day with little to no wind which means that I can't schedule an exact date for the record attempt. My intention is to be ready to go and watch the weather closely, then when a suitable weather window opens up, just DO IT.

Ben came over today and we made some progress on the main hull. This hull is 24 feet long and 9" wide at it's widest point. The Styrofoam plug was CNC machined by Jarrett Johnson in Saskatchewan and delivered to me in 4 parts. I had to build a 24 foot long FLAT table to place the hull onto deck side down.

I am going to use the same composite layup method that I used for one of the outriggers - that is to cover the entire foam hull with packing tape, lay down the carbon, wet it out with epoxy and vacuum bag & cure for 8 hours. Then pull the carbon hull OFF the foam hull. The thin carbon shell will then be reinforced with some bulkheads and a thin sandwich panel deck will be bonded to the top.

I did this for one of the outriggers and it worked, but there were millions of pin holes in the 2 layers of 6 oz carbon I put on. These holes leaked water like a sieve - not exactly what you want for a boat. For the main hull, we are letting a base coat of epoxy on the taped hull get semi-hard before applying the carbon and wetting out. I am also applying two additional layers of composite fabric - 2 layers of 5.8 oz carbon weave, 1 layer of 6 oz carbon/Kevlar weave and an outside layer of 5 oz fiberglass for sanding. I am also going to apply LESS vacuum pressure this time which won't suck out all the epoxy through the fabric which leaves the nasty pin holes.

Ben and I are pulling a length of string tight to make sure that the
4 foam sections are assembled in a STRAIGHT line

We covered the foam plug with packing tape. When the carbon cures,
I can pull the boat hull right off the foam plug leaving the foam plug for future use.

2 layers of 5.8 oz carbon, 1 layer of 6 oz carbon/kevlar mix the 1 layer 4 oz fiberglass on the exterior. We set the vacuum pressure high enough to press the wet fabric against the form, but not to remove too much excess epoxy.
