Aren't Geoff McCoy's nuggets displacement hulls? I'm not even sure what a displacement hull is but I'm guessing the "loaded dome" might be of that character.

If a nugget is a displacement hull I've surfed one. And on McCoy's boards they surf in the pocket. They aren't for flat faced waves although they'll surf them. I saw that Gamboa footage and to be honest I didn't like what i saw of that board. It seemed to create a whole range of restrictions without offering many solutions.

Just my opinion.

Want to know what a displacement hull is?
Read on...from Greg Liddle's website-
http://www.liddlesurfboards.com/origins.html
The experience of hull riding is in the connection with the wave flow for the rider rather than the onlooker.
To the observer looking for top to bottom shortboard surfing they will think not much is happening.
For the rider it's compression and extension and they are harder to ride than they look.

Sounds like a hydrodynamics theory applied to surfing, which doesn't take into account the dynamic nature of surfing and waves.

Whats the general consensus? Good as a go-to board for the average day of Sydney waves? Or only good in certain conditions?

captain, i haven't ridden one, but i think the answer you seek is probably in the locations of those who are obsessed with them.
i.e. southern california, where there's a big hippie vibe and you can ride almost anything because of the (generally small) long period swell and reliable morning offshores
or northern parts of the US where the weather is generally not great for much of the year, and people have far too much time to think about crazy theories and boards, and the skills to shape them. a fair few of those surfers would have learnt their board skills on snowboards too, which is important because hulls are meant to be turned off both feet, and snowboarding on piste the turns are initiated with the front foot.

in the right waves, they probably go unreal, if you're a good surfer, turn off your front foot, normally go forehand, and don't mind eating it 8 times out of 10 for the one ride that really lights up

and i'm not knocking anything huie shapes or says, his boards look unreal and he's got more years surfing than i have breathing.

fong, i'd say they're nothing like a mccoy in the way they ride, given you have to ride them from the front half without much back foot pressure. i've got a mccoy, and if your back foot is more than about a foot width forward of the base of the fin it's a dog to turn.

I agree for once dino. They don't sound like very much fun at all for Sydney surf...Turning solely off the front foot? I can imagine there being a lot of forward drive in a turn like that which could be fun, but at the cost of not being able to turn off the back foot in pivotal turns sounds like a design theory gone bonkers.

I'll stick to my bloated quad mini fish fast easy to paddle things... :P

haaa'' you guys are exactly right these boards are not for your average sydney waves :roll:

the design i am working off. come from a design that was created specialy to ride the point breaks available to our crew in late 67-68 40 od yrs later i have changed it a little :idea:

i guess if i had to name it i would call it ( outside little cove)

hmm is that ringing a bell :lol:

greg liddles boards were designed around m bu rincon

these are noosa in a slightly different vain

remember its not only the show pony that enjoys the ride 8)

hope that helps
cheers huie

Couldn't help myself when I discovered that the guy who'd ordered a 6'2" X 22 X 2&5/8" Matt Keane hull through Beachbeat didn't feel the love after one surf.
He probably tried to do a vertical reo on it and it screamed "NO" back at him.
It will be spot on for through the Nationals carpark or Johnsons.
Take a high line through the dead spots where a cutback will have the wave running off in front of you.
Haven't picked it up yet.
Earlier this week would have been great for it.

Keep in mind that 'displacement hull' is a misnomer when applied to these boards as they are primarily planing hulls.

Probably the only true displacement hull surfboards are ancient olos.

Some of my large pintailed designs use displacement tails and have a higher ratio of displacement based lift to planing lift than any of the boards erroneously marketed as 'displacement hulls' at present. Even so they still gain the majority of their lift from planing once riding waves.

I saw a chick down the beach today with a displacement ass,man the ratio must'a been about 70:30 ass to body and limbs... :shock:

well you are right the heading is the wrong discription of the design i have
but it seems to be trendy to refer to them as hulls
my design is aimed at one special little wave
dont particularly care what its called 8)

That's a lot of roll !

What are their best qualities Huie ?

Do you find them to be fast and smooth ?

I tried one of those extreme V bottomed plastic fantastic mals once about 25 years ago but couldn't ride it.

yea those v bottom things were the worst board i eva rode

the yellow board in pic was the design that i let go of my longboard
from 8' 10'' to 7' 6''

there is a widening interest in single fins again so the design has its place
