Imagine that we went on our fast runway on a speed board. Wind suddenly dropped and we are stack in the water , far away from base. Long swim or call for help the only option.

I have idea, to add volume to the board.Quite often we may go sailing in strong wind on a sinker.
Suddenly wind drops and there is nothing we could do, to get back .
I thought about inflatable.
Something small that can be kept in the pocket, but in emergency when wind die , attach to the under the board and inflate to increase boyancy by required margin 40-50 kg?
Then we could even uphaul the smallest speed board and slowly but safely return to the base.Ideal could be thin , rubber ducky material , that fit perfectly bottom of our board,.
First you slip nose of the board into pocket in our inflatable, extend to the back, secure ropes to the foot straps.
Then inflate. Or maybe you could do even more universal for most of small small boards .

Similar design with front pocket , but averaged width 40-50 cm and 5-cm depth, length ~ 210. ~ 25kg
10cm - 50kg extra boyancy/

Whole process should take only few minutes, but save hours of trothing , swimming in the water.
worst case scenario- we could attach inflatable to the rig, disconnect board and swim back on the board back to base,. Rig will float and will not sink,
another worse scenario, we could swim an this inflated float and leave the rig alone. but obviously our ideal is jump on extended board , uphoal of water start if possible and sail back.

Why not just simply install a lightweight device that shrinks the universe by 50% except for the board . May need to wrap board in tinfoil so it doesn't shrink.

That will be counterproductive. Everytime you shrink Universe, GDP halves and your income too. So board becomes twice as expensive.I hardly could afford new gear already, so doubling the price doesn't work for me. On another hand $20-50 inflatable may be saver for one, money spinner for smart gadget manufacturer. Maybe one of ours could find good business of making those.
Eventually hot iron and sheet of popular foil is not a rocket science and can be made even in Australia, at any garage.
Idea for hard covid times for anybody ?

I think you should make a prototype and demonstrate it's use Macro.

I have now the idea of an ultimate speed racer buoyancy vest for the board. Let's do two tubes from similar material the wings tubes are made of kiting. Two tubes like that 10- 20 cm diameter, 2.3 meters longIN the front of the board they go into the shoe like, pantofel over the nose of the board.Then outside the board at rails to extend widtht for stability. Every 50 cm strap across kept our tubes safe in relation to the board.
At the very end our tubes are connected to a piece of hard plywood.
at this plywood piece additional 40 cm fin could be swivel attached on a hinge or fast insert into box, fast mounting box.
Now, how it works.
Imagine that you need to get easy onto Sandy Point or Burrum high sandbank. On speed board, it takes ages even in the strongest wind. But thank to our inflatable extension you increased buoyancy by 50 liters and have an additional 38 cm fin, behind you board.
Now you could easy,sail to the top point, hard upwind. On arrival to the top, deflate, fold up everything in a small back pack- 2 -3 kg max.and run you,r speed board.

this simple device converts your speed board into an easy free ride everywhere cruising board.
then you could fold everything into your camelback backpack.

as a matter of fact, I have already enough trouble convincing all rocket builders across the globe to switch to my in my mid-air capture instead of VTVL ( vertical take of vertical propulsive landing) .They all do this wrong way - including SpaceX.But one day they will catch up with my idea of mid-air capture or returning rocket boosters with airships, blimps, and line.Once they do this correctly as I ask them to do, I could go to my garage and plastic weld our boyancye vest for boards. The closest so far in Kiwi company trying to employ helicopter.You could not ask me not to build airships and rocket boosters to show how it should work!

But what you have proposed is not rocket science.

Hmmm Rocket pants

You must not understand orbital-mechanics or even balistic-trajectory.... almost nobody does, except actual rocket-engineers.

There is a reason that there is only one rocket to ever consider attempting this [ the Electron ] and that is because the rocket is *exceptionally light* by rocket standards; any rocket capable of launching a human, is simply too heavy and/or travelling too fast.

But do go ahead and tell everyone whom has ever attempted orbital-class-rocketry, that they are doing it all wrong.

It's only rocket science .

Fat tire inner tube, CO2 cartridge, adapter pump for CO 2.

Don't use a sinker where you can't wade, or swim / float back to the beach

No no, we can't be practical on this thread.
Just carry an inflatable raft on your back.

Modern design of airships could handle up 500 tones of cargo. That is more then empty booster by big margin. The problem is nobody is building modern airships. This art must be rediscovered as electric vehicles recently. Airships (cargo) are my favorite and future is enormous.
Beside, there isn't the point rocketry people do all wrong , but something can be made even better. Taking you path we could be still riding horse or steam engine the best.

John, you have been to Burrum Heads. You know well that if you miss last wind gust you may need endure long walk, or stack on the other side forever. My inflatable could be made cheaply and provide pace of mind . The question is, if can be made and if works as proposed? ideally if board manufacturer could offer one day inflatable board extenders for their small boards. Maybe our JP will be first and the rest of the world will follow.

come back to the Burrum. I did drive there one day with one goal only. Get 30ktn NM. wind was fine, tide too. But I took my 118l JP just in case the wind die , so I could cruise back. In the last run to base I had feeling of the fastest run of my life. Sailing head to head with the best in business. On arrival they all had above 30, but my GPS recorded miserable 25. I am sure that having my usual FF99 I could meet the goal this day. My dream is to go one day on my favorite FF 51, 61L To try again one day. But in the case wind die, as can at Burrum, I may be in big problem.
