Take 1/2 cabbage and steam
Cook 10 strips of bacon. Add one extra bacon strip for each expected wave height.
Mix together and heat one last time with 4 teaspoons of sugar.
Eat along with 2 Omega 3 Fishy oil capsules
Wait

When storm arrives take down pants and lean over windward side of boat. Stick monkey arse in water and crap or blow.

BLUB-BLUB-BLUB-BLUB-BLUB-BLUB

see waves disappear.
Patented? I'd love to see that one going through the patent office. "Nope sorry, already 10 others ahead of you with the same idea."

Re: Heave /Hove to -what are the limits?

The ships I went to sea on ( typically 1950's built) all had two wave oil tanks in the focsle... each maybe a cubic metre .. maybe a little bigger.... small diameter pipes ( with valves ) feeding into the hawse pipes.

Never ever knew of them being used... don't even know if they had oil in them...

That would have been designed for use in lifeboats.

Bag was leaky by design and filled with oakum, the rest of the kit was a gallon tin full of wave oil ( colza oil .. https://en.wikipedia.org/wiki/Colza_oil ) and a length of rope. Job done.

Same area hit by SE 60kts which backed up the current creating vertical seas where it was in my opinion to dangerous to have any sail up as it did nothing in the troughs but tried knocking you down as you crested.. seas around 9metres.. duration 50hrs laying ahull.. boat a 30ft Westerly..
There have been other times in a variety of boats in other seas/oceans.
Do what suits your boat and try not to let the noise below and confusion above throw you overmuch.. theres no set tactic to my mind.
Its all down to type of boat and conditions.
Forgot to mention.. during my last two nights before I made it into Viviero (N Spain) on the 22ftr.. three large commercial fishing boats (60ft+) went down within a 25mile radius of me.. 2 Spanish and 1 Portuguese.. this was in December '08 which goes towards my contention that big is not always better.. and the sea and wind speeds were not my estimation but from the Spanish Met at La Coruna..

Maybe some of us should take a gallon of colza oil aboard, test it somewhere, and report back here.

Re: Heave /Hove to -what are the limits?

Oil dripping off your bow ? I can't wrap my head around that concept. Please explain. How much ? How long ? What kind of oil? diesel, vegetable,engine? Why not soap? Soap breaks surface tension on water. What does it do to the breaking waves etc.etc.

Check the videos posted earlier in the thread. It's science, but not surface tension.

There are some better ones but I couldn't find them with the limited time I had to look. Keep in mind that most vessels have a limited amount so use it judiciously.

I'm sure I can find room for a 5 gallon pail if it has the potential of extending my life.

Actually oil does have a calming effect on the sea surface. I lived in Santa Barbara for 11 years and everyone there is familiar with the near constant sheen on the water off Coal Oil Point. And sailing between oil slicks will show the difference. And somewhere I have seen film of the calming effect on breakers at sea upwind of oil deployed. I recall it being quite impressive. But wave period, size and speed are going to remain. And so I do not store the organic grape seed oil in the bow for THAT.
