Sarabande's dye idea

You beat me to it, Sailing ! I am going to have a play with the dye in the murky waters of Plymouth Sound this weekend.
 
IIRC, I’m sure I read somewhere that flouresceine was used in WW2 by pilots who had parachuted into water, to mark their positions for easier location by rescue craft. Is it toxic to marine life Vic?
 
Why not just go out and buy some?

Or is the aim to mark the sea with dye without spending any money?:confused:

Not sure what you mean?
Sarabande mentioned the fluorescein in a post and in a pm he said he knew it had been around since WWII and said Screwfix sell it.

Toolstation sell it too for 98p less.

I bought some in case it is of use if I meet anyone in trouble at sea and Sarabande is buying some to test in his home waters. I made a quick video to show how bright it is.

It can be bought from yacht chandlers and Plastimo sell it in a pouch. At vastly greater expense than £6.

I think every sailor should carry a tub of it (my opinion only).
 
Issued by RAF in the contents of an aircraft liferaft - and, for a number of years - in the Personal Survival Pack fitted to 'bang-seat' aircraft. Featured in all the Sea Survival Courses run by the School of Combat Survival and Rescue, for decades, as there was a ready supply of time-expired sachets. Considered quite effective in quiet, near-calm conditions. Rather less so in 'agitated waters and at night'.

Makes quite a mess....

Why does it need tested? Do you not just chuck it in the sea? Or is the suggestion to do a comparison between Toolstation Drain Marker vs Ocean Safety Sea Marker?
If you are "testing" it, it might be wise to forewarn HM Coastguard - to save an unnecessary SAR or lifeboat callout.

Matters are in hand regarding your last sentence, but primarily with QHM rather than CG.

Are you selling tickets for the show or wanting judges to score the dye.

I have a haircut on Saturday, but could pop down to Jennycliff on Sunday with binoculars and a handheld VHF.
 
Trying to sort out the scrambled office diary ATM. Unlikely this weekend, but it would be a good idea to see how far the patch is visible. I'll let you know when I get feedback from QHM.

Once I bought the stuff from Toolstation, I simply wanted to see what it did to water and how much was needed. I was surprised to see the granules were red. But I concluded that only a few grains produces an intense dye and it is green. I made the video to show others that did not know of it. If they buy it, they do not need to break the seal now and perform a test.

I rarely buy something without checking it is fit for purpose.

I wouldn't buy this tub of powder, stick it in a locker and only bring it out if/when needed without knowing what it does as I imagine you would agree.

Cheers.
