New Oc6

Surprised no one has posted or brought to attention this decked OC6 from Outrigger Connection.

Submitted by Rambo on Sun, 12/26/2010 - 5:24pm



It's another lightweight M2 with an added custom built top deck, aluminum iakos that enter the hull and ama like their OC-1's. The Vosa is too light (only 160 lbs.) which was made before the updated PA'A 'Eono 2011 rules, doesn't meet with the PA'A unlimited hull weight restriction of no less than 200 lbs.

Looks like they'll be a lot more crews in the unlimited class entering the 2nd Annual PA'A 'Eono come 22 May 2011.

this is awesome. the more the better! i hear rumors of unlimited boats being built by a new manufacturer on the big island in the very near future as well. great times are these! great times indeed.

a very smart choice for OC to use the same hull/deck/manu. no need to build 100% new molds. i'm sure the weight reduction alone will make the mirage an even better canoe. is that also a puffy ama? very cool.

I knew of the Vosa but not with the add-on deck, that i haven't seen before.

Rambo , look carefully at the seat arrangement. The seats move more to the center of the canoe. 4 seats between the iakos.


#4 Sun, 12/26/2010 - 10:34pm


from the picture, it doesnt look like it has a seat 1. and there are only 5 guys paddling in the upper right picture. maybe an oc-5?


#5 Sun, 12/26/2010 - 10:26pm


No need for a steerer, seat 5 controls the rudder so all you steerers out there had better start learning to paddle...hahah

from the picture, it doesnt look like it has a seat 1. and there are only 5 guys paddling in the upper right picture. maybe an oc-5?

There are 6 paddlers in the upper right picture. The front iako is in between seat 1 and 2 while the rear iako is in between seat 5 and 6. Seat 1 is actually further back from the front probably to compensate when the nose is high in the air and he can still paddle. The middle four seats look actually much closer than normal to squeeze in having four paddlers inside the iakos. That would bring seat 6 forward as well so that he is able to steer/paddle when the tail too is in the air.

In talking with Karel Sr. the reason in just using the current M2 mold/design is that it is a proven craft that works and didn't require him to make a completely new design from scratch or the extra time/labor. He also mentions the fact that since we are in Hawaii, we should be using Hawaiian designed crafts in our waters.

Other canoe makers should follow this concept to just use what they already have (previous design molds) to make a canoe with lighter materials without having to create/design a new unproven canoe.

Imagine Team Bradley and Team Primo on Ultra Light Bradley Lightnings for the 'Eono. They could have 3 of them, 1 male crew, 1 female crew and 1 mixed crew with their existing members.

Yes there are 6 seats only joking here is a larger pic.

The individual skirts is a cool way to go for water exclusion, definitely not a changeover boat though, you would never get in with those skirts on.

The four center seats do look very close together, maybe require a paddle c/o technique tidy up. Maybe not a bad thing if it encourages a higher tophand technique more like what the Tahitians do.


#10 Sun, 12/26/2010 - 11:22pm


i wonder if all the seats being bunched together is a function of the boat being very buoyant now. In the OC blog it says this was to keep 1 and 6 close to the water. were the ends getting too high out of the water? the mirage probably has a ton of extra buoyancy since it was designed to be 400lbs + canvass + iako. cut the weight of the hull by more than half and you suddenly float a lot higher I'd imagine. clever solution to bring everyone to the center of the boat!


#11 Mon, 12/27/2010 - 10:02am


Keeps the ends lighter. Boat will react faster and not bury as much ...

Adjustable seats would be great here too ( or any boats ) to fine tune for paddlers and various conditions.

Proven design, 160 pounds ... built by Karel ... and its "not allowed" .... sigh.
unlimited indeed.

Funny, didn't notice the new iako placement first time around. Onno, I had similar thoughts about the boat reacting faster. Just did a quick estimate of the total moment of inertia (ie, it's resistance to pitching from its mass) and looks like this seat movement could reduce that number by 10%. Based on 50" seat spacing, a crew of 180 lb paddlers and a 200 lb boat. Also, neglecting any weight from the ama and iakos. I don't really know how this translates to performance, but this number seems pretty significant. Certainly a great idea worth looking at for possible performance gains, aside from tooling and paddler comfort. I'm curious if they tested both configurations with the same canoe. Pretty cool.


#13 Mon, 12/27/2010 - 1:46pm


I was just guessing since the OC site itself said that seats 1 & 6 were moved to get closer to the water.


#14 Mon, 12/27/2010 - 1:50pm


another interesting calc. There's about a 10% gain in moment of inertia from a 22 lb oc1 to a 19 lb oc1.


#15 Mon, 12/27/2010 - 1:53pm


so a light boat would be a squirrelly bugger compared tongue same boat that is twice the weight?


#16 Mon, 12/27/2010 - 2:31pm


Keizo - ??? that is not too intuitive, it seems if the hull shape was similar you would have a 10% reduction. To increase the moment of inertia with a lower weight you would have to move the mass further from the rotational axis. Is that the case?


#17 Mon, 12/27/2010 - 4:18pm


Pretty cool canoe.

Would love to see more pictures.


#18 Mon, 12/27/2010 - 5:17pm


Kaiwiki, that sounds right. Moment of inertia is just a function of mass and it's distribution. See wikipedia. I'm making some pretty big assumptions (canoe is a simple rod, people are point masses) to make simple math, but I think the information is useful enough.


#19 Tue, 12/28/2010 - 8:45am


I can visualize an ice skater spinning, and sticking out their knee or arms or tucking them in to increase or decrease moment of inertia, but a canoe spinning? Perhaps with deck and skirt, we're talking air chamber or hollow rod? Haaaappy nuyeah!!!!!

How do you bail with such small cockpits ?


#21 Sat, 01/01/2011 - 7:37pm


I guess the skirts are very water tight Hiro, they certainly look that way, same with the hull, or maybe they planning on small bulge pump.


#22 Sat, 01/01/2011 - 11:00pm


what happens if you huli??


#23 Sat, 01/01/2011 - 11:37pm


always a good idea to pump your bulge, eh Rambo?


#24 Sun, 01/02/2011 - 8:08am


Hey jc,I get pretty pumped just looking at those super-fast liteweights, no additional "motivation" required...... i do need a spell checker though...haha

Even the automated spam checker is on to me, no BS this is what it asked me to type...how funny's that.


#25 Sun, 01/02/2011 - 11:55am


Akpaddlestoo,

Hip snap and roll it up : ) : )

aloha,
pog

quick edit for Rambo reading this ... LOL ... I know what you mean, sometimes the capcha thing seems like its reading the thread ...

this one right here >>>> Imagon Was


#26 Sun, 01/02/2011 - 10:52am


k

cool innovation, I hope they race it, OC has clearly spent a lot of time on it. in terms of visual appearance the additions remind me of a skoda. i do like the old lines of the mirage. the iato placement between 1 and 5 is interesting.

im still on the fence about weight dynamics and hull shape as the resistance levels change so much after your alter the design waterline specifications.


#27 Sun, 01/02/2011 - 10:54am


Rambo, that was awesome.


#28 Sun, 01/02/2011 - 6:47pm


Yeah, and i though the Google Ad's were funny sometimes..

Hey that sounds like a good name for a car license plate. ...

  • Wanged His

    #29 Sun, 01/02/2011 - 9:05pm


    you could probably get away with Bulge Pump.


    #30 Sun, 01/02/2011 - 9:12pm


    ... then i'd need a Plumbers licence.

    Speaking of which .. where is ButtAid ??


    #31 Mon, 01/03/2011 - 12:17am


    Nice job!
