Yep, defo Sue. In FangyBargearse terms, anything less than triple-figure kegs doesn't even count as a real weight.

Weird that you already did then.

Did I miss something, 79-80 kts are knots for our use.

Other well known is Klippel Trenaunay Syndrome.

Whoops.. definitely not for lightweights..
70-80kgs...Blasted mobile..

Phew! Good to hear I am still a 'lightweight'. I thought I was getting fat!

Oh come on Daffy, that is like giving me a free kick on the goal line...the temptation is killing me

I am 100kg on a 148 litre board with 48cm fin. Ezzy sails 5, 5.5, 6.0, 6.7, 7.5, 8.5 and recently bought a foil to increase the fun on light days. Most frequently used sail is the 7.5 followed by the 6.7 in winds 15 knots to 25 knots. Being heavier than most sailors around on the beach, I usually get strange looks when I rig a sail 0.5m to 0.7m bigger than everyone else, but it works. I am lazy, I suppose ,because I don't really pump the sail. I just wait for the wind to do the work. I do find it pretty easy to sink the tail if I'm tempted to move my feet back too early in marginal wind. I also agree the Ezzy sails have fantastic range, add extra down and out haul and they will let you run them in way higher winds than you think possible. From the photos and what you said - I would move the mast foot forward, keep your back foot forward of the rear straps until you are really up and planning and sail that 8.0 as often as you can until it is being torn out of your hands. ps. I've used the 5.0 and 5.5 in 35 knots and it is a very different feeling that takes time to get used to on a 148 litre board. Keep going and Good Luck.

totally agree .
Twist weight forward ,
Go big ,
Dont whinge ,
For we are beautifully robust
Tailwalking is something less robust challenged imagine happens
Its only happened once , to me , so realistically never happened .
Fin big I say .

Yes.. That's some good stuff right there... Thanks 10^6. its 8.0 and 6.5 from now on.... The system HAS to be balanced.

The center of lift has to be between the my feet... Will post pics as soon as the wind starts to blow... Thanks again

Hi Eddie,
Could you forecast some wind for us here in South East Queensland?Local weather bureau has been doing a piss poor job lately

Eddie - I was going to say it isn't a good idea to post on Seabreeze that your job is a meteorologist.. You'll get blamed for all the wrong forecasts!

I can forecast you some wind no problem... but it will be wrong. But that's no problem, I get paid the same either way.

Ok.. I have been busy. I have taken all the data from the experienced people here, the pictures my wife took of me sailing
and what I felt sailing this 150, and built a new board.

I want a easy to ride board with all my sails. One scaled up for my size and similar to my old boards from the 90s.

I want a board my 11 year old boy can learn on, that is why it is long and pointy.

So I built this, my 4th home made board.

Note the two mast tracks... Everyone here said move the mast base... Well I had been moving it all over every day I sailed.
No help. I am hoping I can use the 5.5 on this board by moving the sail far back in the second track. This will put the center of lift back between my feet.

The foot straps are more forward, not much.

The new board is longer and thicker in the back. Just a bit wider at max and wider in the tail.

Many of these changes I did will slow the top speed of this board, but that's ok...
There is only one or two other guys around here that sail, the rest kite.

I have no idea of the volume.

Nice job there Eddie! Let us know how she goes.

Eddie,
Owned a 150 Shark for a few months during my early progression. If I remember correctly, I found that mast track back 1cm & footstraps forward and out worked best for My sailing. The board felt very sticky and required more wind than you'd think. I had to push it hard off wind to get it to unstick. Sails used were 6.5 & 7.5 Cheetah's in ocean conditions. Anything under 6.5 at my weight of 93kg's, and the board wasn't fun. Also, the stock fin was thin & didn't have enough power for heavier riders.
Replaced the shark with a thicker tailed futura... best decision ever!

Great looking board!
Maybe some outer strap holes?
Let us know how she goes....

What model futura... I would like to see a pic.. Thanks

It's a 2014 wood version. Still in use today with sails ranging from 6.5 - 9.2 at my weight.

A few things need to be said.
I'm 85kg, so "light weight", and :
- at 15-22kt I sail 7,8sqm freerace (3cam Stype NorthSails) on 112l board which let me think that you should not be afraid to keep your 8sqm into 25kt...your 6,5...well, probably around 25-35kt... if you dare with 150l...the board may want to sail herself.
- modern board, like the shark, needs to bear really downwind to start to plane, and be pushed with a little pumping, once this is done and feet are in the straps, it is possible to slowly point upwind. This will require to forget your basics of 20years ago.
- modern boards are much more fun than our 25-30 years old gear... keep at it, just learn the new tricks....
- I would invest in a 9sqm, depending on the wind stat at your place to be able to go sailing by 14-18kt.

Good luck and have fun, it will come back, you will enjoy and be able to gear down your board in a year.
plettil

plettil... that's some good advice.

The pic below is from a few months ago... my first day back... 28 knots easy.. sand blowing everywhere.
that's my 5.5 and Shark 150.

Now remember, I was the best around these parts... by a lot.. fastest, bigger jumps, all of it.

But on my first day back (pic below) ... I would sail out 2-400 meters and sail back, only planing in the straps 2% of the time...
Catapulting and crashing the rest. At the time I just thought I was over powered, than I thought it was just to rough.
But the more I thought about it... I was just unconformable... the foot straps were too far back. Nothing worked.

My friend had a 6.9 and got no where except downwind

I went out many times and always made it back to the same spot.

After all that... We still had the best time. The 2 hour drive home was just fun even though we both failed badly.

As I type this... I still remember that day, sheeting in, picking up speed, moving my feet to the straps then being all out of sorts and crashing.

I don't care about crashing, but I remember days where I would sail and duck jib all day and not fall all day.

But... with everyone's helps here... I am narrowing down on it quickly... Thanks again everyone !!

I have a new 8.0 I am going to use from now on with a bigger board... Because of what was said here it should be fine for a lot more wind than I first thought

Eddie Weeks

Here is my 8.0

This is the only sail I got in the straps and was stable until I hit a lul.

Is this a decent modern sail.. its a 2016 model... Thanks again

Eddie

Looks like it needs heaps more downhaul.
Most modern sails set with the top couple of panels floppy.

ok... Heaps more downhaul... no problem...

Tons more... so did your Ezzy form the other pic. Are you rigging at least to the numbers? That 8m for example should have a really floppy leech down to about batten number 4 or 5. Certainly none of that wrinkling in the luff around the boom area (those two are a dead giveaway)
The 8m will take all your strength to downhaul it enough so believe the numbers....

Same with the smaller sail your dragging to the water.
I rig by visuals .
Between the second and third battens from the top , there should be a slight loose crease from the leech to at least half way to the mast .
You may have to extend the extension .

Around the 9 min mark.

Downhaul your ezzies 10 - 15mm past max downhaul in all conditions.

So I was talking to a sail maker the other day, about downhaul and floppy leaches. His take is that, older sails had draft the whole way up, so it was easy to design in a fairly constant leading edge entry angle, all the way up the sail.
Modern sails with their twisty heads, need the top section to be flat. So there needs to be enough downhaul to achieve a constant entry angle up the luff under load. So bagging the sail out, by letting off downhaul, is counterproductive. It may give much more draft low, but the head is going to stall when sheeted in.
This was probably your main problem on your first sail.
Underdowhauled modern sails are horrible!!! Heavy, draggy and slow, with the correct downhaul they should be light and fast.

Get a rig winch to save your back..
+1 re under downhauledsails feeling horrible..
With the leech floppy it should exhaust excess wind and be easier to handle in the stronger wind.

The centre-of-lift isn't really a thing for a board (it is, but given the lack of downhaul...) - do you mean centre-of-balance? Can you explain what you mean by centre-of-lift (because it is unlikely that it should be between your feet)?

PS. another tip.... grind that point off of the board.... unless you like sails that are to become Swiss-cheese.

Some of my experience is in aeronautical engineering and a wind has a center of lift just like a sail.

A plane has a Center of gravity and a center of lift... its best to have the CG ahead CL and the tail fins push down and line everything up.

On a sail board, the wing/sail has a lift vector which is balanced by the fin and board drag.

It is possible because I did not have enough downhaul or washout the top of the sail was pulling hard.
This made me hold the sail more upright, as not to turn up wind as the top of the sail is far aft.

(My theory)
Back in my day, any board could take any sail mostly because the foot straps were further forward and more forgiving
at the expense of speed. (more board in the water)

This shark 150 like modern boards, have the foot straps back and far more sensitive to the sail if its not in the right place.
At my excessive weight, this just exacerbates the problems

I totally agree with everyone here about more downhaul and bigger sails for my fat a$$... LOL thanks again
