Just thought I would post a message to show that the 80's are still in vogue - go for a sail in the Whitsundays, and windsurf in the white sands of Whitehaven Beach.... a few friends decided to hire a catamaran for 5 days.

After a 4hr briefing, we set out from Airlie Beach. Sailed out to Langford Island Reef on the first day - was blowing 22kn most of the way, which made for a an 8+kn cruise across the wind. Got there a bit late in the arvo, and being the first day on a new boat, we missed the timeslot for a windsurf. Some of the passengers got their first taste of forgetting-to-take-TravelCalm !

The next day we headed off to Whitehaven Beach... the pics from the 80's kept us calling. Got there just after lunchtime. Some of us had a good session in the clear water and white sand. Wind speed was at 18kn.

The third day had 16kn, so bigger gear.... but very fun !

4th day was about 8kn, so a swim and snorkel. Then a downwind cat-sail back to the inner side of the islands.

5th day back in the marina.

It was a good test for the viability of such a cruise. The skipper has sailed across the Atlantic Ocean, but that was 20yrs ago in a mono-hull. Rigging the gear on the deck, turned out to be easier than expected; connecting/disconnecting the mast-base, was harder than expected. Anchoring up in the wind, needs a lot of practise and a lot of patience. And then there is the logistics of getting everything on board, setting used to stocking the food for a week, etc.

Thanks for your help
But I want to learn freestyle in parallel and I think that the freewave would limit my progression


The phrase "freestyle wave" is pure marketing BS - those two disciplines require distinctly different board shape. Dont be confused by the poor marketing.

You certainly can do "modern freestyle" on any board type - such as a wave board. But it is significantly more difficult to complete any of the modern-freestyle tricks using a non-modern-freestyle board.

The "classic freestyle" (carving 360, etc ) generally can be done on any type of board (maybe you are thinking "classic" ?).

Choose the style of sailing you want to do, then purchase the gear for that style.

I'm am after more on the flotation side of things, we all end up in the water at some time


We all end up in the water at some point. The question was more of ... do you need an "official vest" (say a real life-jacket or other high-buoyancy vest) or just some extra flotation.

All vests give flotation - you will be surprised how little extra you need so that you float higher in the water. It isn't unusual for people to float (in ocean water) even without any extra floatation, and for those people that sink most only need to hold their breath to float. As such, you only need a few litres of extra floatation to make a significant difference.

If you sail with other people, and if they are using a vest, ask them for a try with their vest.

Two cameras. Seriously. One on each side of the boom, either at the tail or at the head.

Harness mount - it sticks out backwards at 60 degress (from horizontal), can use a go-pro but IMHO a 360 cam is better.

Mast mount pointing towards the nose of the board - Ben Proffitt uses this a lot.

I wouldn't say Greece isn't windy... it has Karpathos for speedsailing, and Vassiliki for freestyle - both require high winds.

Its ok spend an hour, two hours, 5 hrs driving each way to the water. Its ok to spend an hour complaining about the wind and not knowing what gear to rig. Its not ok to take an extra 20 seconds to thread a pulley. What TF is the world coming to ... ?

It does not matter what the orientation is... it only takes a few seconds of brain power to thread the pulley, stop over-thinking it.

One of the best things to do for the plug - in my righteous opinion - use two o-ring's.

It is what is used on diving equipment, so we should learn from that field of expertise.

The shape of the sail is dependent on the correct mast and the correct downhaul tension. Both work together.


All of these explanations are good - I could not have said it better.

Just to add another variable - your weight. As noted earlier in this thread, the 30kg weight is there to set a baseline. Is it a good baseline? ... Importantly, the static mass deflection doesn't measure dynamic response (which I think is probably as important to the "is this the correct mast" question).

Another nice day, a bit gusty but nothing to complain about - nice on the 4.2m. Wind direction was SSW.

Some nice little ramps on the inside; even with the outgoing tide, there wasn't much current at all. The outer bank had big holes in the wind making it a bit unsafe; outgoing-tide making it a bit of a washing machine on the outer bank.

Went around the old lighthouse, there is a solid wave just to the south - to get to it requires sailing through the outgoing current, so it isn't for the faint of heart. Which also means, dont fall on that wave...

Then the wind came in SE... time for some speed runs. The edge of the bank has changed a bit since a few months ago, no longer straight... but still good enough for 36kn.

As one can see from the track, the satellite photos are quite old...

All batteries - lithium included - will have some self-discharge. This is an artefact of chemistry and of construction. We do see come batteries marketed as "long life" - their self-discharge will be small, lasting 10yrs or more. All rechargable batteries are considered to be *not* long life - lithium cells are quoted asa 1% per month / 10% per year. Importantly, if a lithium discharges below a certain threshold - 2v per cell - then they are considered to be unsafe to be recharged.

Thus a typical suggestion is to charge them at least once per year or two.

Some manufactures stipulate more often - for example, DJI drone batteries have a self-regulation mechanism which discharges sooner, so need to be charged about once per 6 months.

Note - new gadgets dont often come with full-charge in their batteries. This is primarily for safety reasons, because charged battery can let out the magic if it gets bumped a bit hard. And during the manufacture of the battery it wont get charged up completely, and the manufacturer of the gadget also wont charge the battery. So you will want to do it sooner, rather than later.

The answer of gusty holey conditions is to foil


A very small movement of feet or change in mast-foot pressure, does require a change to pitch/roll/yaw/height. ( This is a result of physics and nothing to do with opinion. )

Are you suggesting as a way to improve technique - as it certainly wont be less-sensitive to gusts than on a fin ?

A few days later another good session. Good wind and waves - 4.2m and freewave. Great jumping waves this day.

Sunday 4th July ... Bribie Bar is working well.

Tide wasn't too low leaving enough water across the bar. Very smooth on the dead-north edge of Bribie Island, which then leads to some nice ramps.

Once the tide changed, the waves on the outer-ledge were holding a nice bottom turn (but only a single turn).
