    V11G outrigger shell in the vacuum bag

    V11G outrigger shell pulled off the foam plug

    My first carbon outrigger popped off of the Styrofoam plug nicely. The general shape is very true, but there are small imperfections on the surface finish due to the release film creases and some imperfections in the styrofoam. These could be sanded off, but I think I would be worth adding a 5 oz layer of fine fiberglass weave for sanding. Then i think the surface would be very smooth.

    This is a great way of using Styrofoam as a re-usable male mold (plug). Just cover it with packing tape.

    I will probably leave about 1/4″ of the flange around the edge to bond a thin top deck to it. The top deck will be carbon over a 1/4 inch sheet of Styrofoam or core material for the top deck. To stiffen the outrigger, I’ll add a bulkhead to the middle. I will also fill in the inside nose and tail with some micro to give it some strength.

    Getting ready for sea trials

    Dates for the second set of sea trials have been finalized. I am heading out this Saturday with Murray. We arrive in Tofino on Sunday and launch WiTHiN. Monday morning we meet up with Matahil Lawson and his boat. I’ll be spending at least 8 hours on the water. The objective is to head WEST as far as I can for 4 or 5 hours, then turn around and head back. Mat also knows of some great areas to get into some chop and swell and other various challenging conditions, so maybe we’ll play around a bit. Tuesday will be more of the same – two 8-hour days in a row out in the Pacific.

    I need to establish a speed profile for WiTHiN. I need to know how fast she goes into varying degrees of head wind as well as from abeam and from astern. Knowing the differences in efficiencies between the prototype version and the new ocean crossing boat, I will be able to predict a speed profile for the new ocean boat.

    This is sort of important, as I need to get a better understanding of how WiTHiN will perform in adverse wind/sea conditions. Most of the ocean rowing boats can’t make headway in moderate onshore winds. This is one of the reasons why they have had difficulties in the past getting away from California for ocean rowing expeditions to Hawaii and Australia.

    One of the things I needed to fix on WiTHiN is the nose ring thing. There is a steel tube that runs through the bow and the stern. During the last trip to Tofino, we ran a rope through this tube for towing and tying up at the dock, but the rope was cut from rubbing on the sharp edge of the tube.

    Since being able to accept a tow is a very important safety issue during sea trials, I decided to fabricate a bridle to tie the line to. This won’t stress the rope like the old set-up did.

    I made a couple of foam inserts for the Dorade vents. These will be used to stop road crap from being blown into the vents during the drive, and – more importantly, to stop water from leaking into the boat when I tip her over beside the dock to mount the keel.

    Another addition to WiTHiN is the new nifty clamp fan. It really blows, and I can mount it in a variety of places using the handy clamp – to face the window to de-fog, or face me for cooling.

    All I have left is to re-build our rotten wooden boat stand on the trailer. This got so wet during the first Tofino trip (snow and constant rain), that it started to fall apart. I’m going to weld a steel one to replace it.


    Tomorrow I have an 8 hour INSIDE training ride – UGH!!! It’s snowing and minus 17 degrees C right now, so an outside ride is NOT in the cards unfortunately.

    After a rest week last week, I attempted a new 20 minute power test today and I was pleased to find a 15 watt increase over my last test. My goal is to get up to 270 watts for 20 minutes and I’m pretty sure with another set of CP 20 intervals over the next 6 weeks, I’ll be able to achieve that – and more, once I get outside. My peak CP20 power was 300 watts a couple of years ago on my tri bike. It’s always lower on the recumbent – I think 280 was my PR on the bent.

      On my catermeran design from my old rowing shell using one hull I just sat on and used my two styro foam paddle wheels as outrigers that were direct drive by one bent 1/2 alunimun tube that I just adjusted the bar hight to how much water I wanted to push. I still think it may be a faster design

      Hi Greg:

      How did you arrive at the unusual shape for the outriggers – Most outriggers are designed as deep vee hulls with upturned ends, with a view to giving progressive flotation the more they are immersed. do they mount vertically or horizontally?
