Osmosis

[myoldsailor]

Hi!

On my yacht, some areas are indicating reading of 40-43 on the sovereign reader. (relative scale)

No sign's of blisters or delamination

Should I be concerned? ie. Insurance?

Regards

Remember Jerome K Jerome? Never read a medical book, you will soon find you have every malady under the sun. Oh, and throw that meter away. /forums/images/graemlins/cool.gif

Make a note of the actual readings in your maintenance log and in which position they were taken.. Enjoy the season sailing.....next winter in the event you are concerned then tak at least 8 readings each side of the boat 4 above the waterline and 4 below and show these on a chart and file with the readings you have. Following year take same again and only then see if you have enough reasons to get into a panic and start asking questions about removing gel coat.

The readings of Sovereign meters and others are more or less meaningless unless taken systematically as they do not really give meaningful absolute readings .

Insurnce companies will have no problem with moisture meter readings. In fact if I was an insurance company I would have more concern with some of the bodged and overshaved hulls I ve seen.

Enjoy your sailing and just worry about wether you need non skid coasters for your wine glasses or a decent bimini in case the sun shines. Forget the O word.

It's all comparative... what do the rest of the hull say.

Did you properly clear off the antifouling to take the readings? Antifouling retains moisture, so you may just be reading an area where the rain drains on to the antifouling, the high moisture being in the antifouling, not the boat fabric.

If you only have a couple of patches that read higher see if there is any reason... favourite really nasty one is stringers or mouldings inside the hull that are holding trapped water.

If the whole hull below water line is high maybe worry if you have a double skinned boat (Sadler 26/29/34, Dehler I think ... various others). I did have a survey done on a Sadler... the hull was reading high, when the surveyor looked at some screws three quaters of the way up the hull on the inside he could see rust streaks where the water trapped in the hull was coming out!. By the way... most Sadlers are dry as a bone I hear.

Worry for a whole couple of days, write it all down, forget about it and go sailing for the year. Try again next year

PS... you could try drying out the hull in the Green Gini patented method...

Ship yacht the length of the country to osmosis expert.

Have said yacht stripped for application of cloth & epoxy.

Have another yacht park next to you...

Have old bill call y'up at 4 AM to tell you that the hull did get REALLY dry for a bit... because the boat next to you is on fire... then really REALLY dry as the fire flashes over... then not so dry when Jones the hose arrives to quench the conflagration.

Apologies for the rant... this whole business is still bugging the bits(misprint) off me!

Really... stop worrying... go sailing.

No signs of blisters or delamination...then forget all about it! If a few isolated blisters occurs, just clean and fill them, etc, etc, each year until (or IF) it becomes obvious something more drastic is needed. May never happen.
