5 fin pics

Post by hart »

Try

album_showpage.php?pic_id=1461

and

album_showpage.php?pic_id=1462

but note that this board is an extension of a thruster..rather than a morph of a quad

cHEERS hART AND Pieetry

Hart sorry if this has been said before but whats your theory on the 5 fin against the thruster

I will take it for granted youd be into it over a morphed quad so from a perspective a quinnie is not really an extension or a step along from a quad

and that board looks great

i could be happy to be a fashion victim :wink:

Thanks Bruce,Surfhorn think I may have spotted my knew board.I can remember when I got my fist tri fin ,my mates were on their NEVER to be replaced twin fins :wink: [now coffee tables].Bruce is so right dont blame the board which I wasnt,its doesnt suit my style of surfing.Dorje as far as giving me surfing lessons :evil: .No decent board will slide when on the rail,The problem "I" was having,to try and give a single example was on a vertical hook type re/entry,hard bottom turn on rail {fine}straight up towards lip {fine}rail again hook {fine} at this point the rail has to leave the water to straighten up and when the slide was happening for "me"cant always be on the rail{have to transfer sometime} other wise youd be doing circles :wink: Love, Peace and Rocket Science. :D :D

Dearest dogtown

the thought that i was giving you a surfing lesson never even occured to me - heaven forbid - you sound like a better surfer than me - im still learning about rails in the water and boards that turn on their fins and i have only been on a quad for two school terms after 10 years on a twin with a stabiliser that i called a tri

I hardly ever post with a particular person in mind unless i direct a question to a person as in my question to Hart above - i just repond

however

it is dorje with a little d not a capital D and that is for philosophical reasons and fun

furthermore

rocket science is incongruous to peace and love but im thinking your being ironic

oh

and dont mind me - i just heard i missed out on a teaching position that would save me 4 hours travel a day so ive taken the above oppotunity to mildly vent

but it was at a private school which did not suit my politics so i guess im able to hold true to my quality public education for all philosophy

and

im not a surfing teacher

my expertise is numbers to 20, shoe laces, show and tell and spelling the word "be"

:wink:

dorje

as kid runs past my classroom window telling another that they need to do a pooh :?

dorje sorry to hear about the teaching position,I have been guilty myself of doing the same thing on this site.Totally understand you being pissed off as when I first moved permanently to the island I had to travel 4 hours a day for my job :cry: .Scored a great job as night fill manager at Coles Cowes, dont start until 5pm get to surf twice a day{surf permitting}.great job+heaps of surf =one happy puppy. regards dogtown."love peace and kneeboard development" :wink:

5 fin

Um..I can't argue against the thruster concept..but I can talk about the benefit that the 5 fin in the pics acheives.

The board is essentially a true thruster..it just has a couple of half-moon drifters out near the rail.

But if you look closely (pic 1462) you will see that the drifters have zero toe-in..they in fact, run parallel to the stringer.

They are also positioned wide enough apart to be on the outside of the plane of the principal rail fins.

The fact that they are parallel (seems) to mean that the watershed that these fins create is directed onto the base of the curved face of the (Al Merrick) rail fin. And the quicker you go, the more you feel it.

The board feels as if its got a lot more squirt..especially when its being turned. It responds quickly to changes-of-weight.

And they are actually so far up the bloody board, you just dont 'feel' them.

The board is a trip..especially in steep stuff. Lots to hang your hat on :)

hart

Oh..and its h not H for equally philosophical reasons.... :wink:

VERY intersting hart!

do you recommend them to customers or just supply on demand waiting for the idea to catch on?

The one aspect that initially appeals to me is the hold factor - this aspect is why i have been happy with the quad to date - it holds on steep drops - a feature of the lower tide wave at the top end of 13th

and

cheers dogtown - perhaps after harts explanation quinnies might come along more frequently - as i said above its been the hold of the quad that ive most enjoyed relative to the old board so the 5 could be the go

now about that slide problem perhaps if just did your shoes laces up and counted to 5 in twos.................... :wink:

I don't think it's the number of fins as much as the board design that determines it's 'slideability'. :shock:

As John mentioned Fish, whether twin keel fins or quads, tend not to slide. :D

On the other hand, rounded pintails do. Number of fins, placement on board, rider's style, etc., all have an influence, but compared to fish in regards to slide factor, well let's just say, there really is no comparison! :wink:

I agree with you Bryan

Bruce, at the risk of being a non believer I suspect that the effect you are seeing could be equalled by using longer (not bigger) - maybe more upright rail fins. Be interested if you remove the half moons and try 112mm base by 130 tall rail fins (AMs are 119x120). The G7000 would be about right size but raked a bit much so too short and the FCS foiling is appalling (might as well cut off the last 20mm of tip)

Hey Red..

(I owe you a phone call)..and I'm not going to call you one of the Monkees because I know you will be a believer..soon.

Bryan is right..because the American experience with quads is so different to ours. We are so oblivious to the influence of the true fish that it defies mention.

My concept of the Lis Fish and other US quads is one of total tightness..quite the opposite of what we see at home. Almost uni-directional with an absence of slide and an emphasis on bottom-turn and push-the-hell out of here. Fullstop.

And I have surfed Windansea on a double-wing pintail and it ripped..but I surfed the same board down the beach at Big Rock..and wished I'd stayed sitting inside :oops: ..like way north inside..in my own comfort zone..the beachy rights through the kelp that kept the onshore at bay.

Couldn't imagine paddling out at the Wedge on what I ride at DY..or what I took to California that year.

dorje..as if it is for the masses.?.and as if they determined what we do anyway..or think.. :) ..You know the story..its there if you want and dissappears if you don't.

Just like the sunshine we'll see tomorrow.

hart

PS

Red..the amount of water you feel pushing off your bottom that these fins pick-up is not the same as what you feel with deeper fins..it's different to that cause it happens further forward.

Its happening earlier?

Bruce - you wrote - "My concept of the Lis Fish and other US quads is one of total tightness..quite the opposite of what we see at home. Almost uni-directional with an absence of slide and an emphasis on bottom-turn and push-the-hell out of here. Fullstop."

I was thinking much the same - I have seen plenty of shots of super powerful bottom turns but can't think of any good cutback shots - are there any out there?

Will the boards do this - album_showpage.php?pic_id=774

That board is a 3 fin rounded pin [no slide!]

Adding a center fin to my quad made a very real difference in the way the board rode. But this is the first board in this new series. I had given quads a try back in the mid 1980s but went back to my tried and true thrusters for many years.

When riding my fins forward quad this year, I loved the speed down the line but didn't care for the loosness I felt when cranking a turn. I added larger read fins but that still felt too loose [Futures: front fins are 5 1/4" more upright fish fins; rear fins are Merricks AM2]. I always had feel that the tail was going to slide out on me, though.

But with the addition of a 4" center fin.... VIOLA! The board retains the great speed, can hang WAY up on a wall past verticle and I can go out on the shoulder and crank one heck of a full bore cutback. And this is just my first board with longer length and increased width.

This next year I plan on trying various fin set ups and templates in the quad before I cut out a new KB....I really want to test this shape by changing as few variables as possible.

Maybe you Aussies need to come over to Santa Cruz this Fall for the US Cahmpionships in mid November. You can ride some of our boards in really great waves. Plus we have some killer brew pubs!

Windansea and Big Rock are such totally different waves, amazing only by the fact that they're a short walk down the beach from each other. Big Rock scares the hell out of me, even when it's small the water draws off of the rock shelf so quickly. Most of the time when you watch, even when it's good, the guys taking off are making it all the way through maybe 20% of the time. The rest of the time it's take off, pull in, pray, wipe out. No fun getting dragged across that shelf, or trying to punch through the next wave with the rocks nipping at your flippers. The board for that wave is one that will get you in as quick as possible -- no time to waste with pleasantries or any "hi how ya doing what's your sign", just get down and get in. I do want to try the Blast Fish 2k at the Rock next time it's good, though. When it's not good it's a close out 100 % of the time. Thanks, but I'll take my chances weaving thru the longboarders at Windansea.

And by the way, I'm fascinated with the 5-fin concept ... maybe next board?
