Re: Old Wives Tales

Pete's right, a whole stock of bananas ripens all at once.

However, that's why people exchange recipes for banana marmalade, and various forms of banana bread, and banana chips.

Bananas are not bad luck, necessarily, the old wive's tale that Iron E referred to. Their ripening is a gradual process, and you may find yourself giving a number of hands of bananas away before leaving on a long passage. Bananas purchased in stores in many nations are ethylened before market, and their faster ripening is one of the results. Bananas given or bought in the tropics have lots of air circulation, and their process is slower, and only the banana's own ehtylene has an effect. If you have too many for your own consumption, it is a time to make some new friends via a gift of a few ripe bananas. To my taste the island banana finger ones are absolutely delicious, better than the usual Cavendishes you find in chain markets, though we have a friend who likes the Cavendishes better.

well, after many, many cosmetic and not so heavily structural projects I have done this way, I can safely say this is a wives tale. It seems to stick as good as epoxy, although I have not done any destructive testing. I’m sure the bond is a little bit weaker, but it’s certainly pretty good.

Are you fixing ? Or are you building ?


For fixing, epoxy sticks to epoxy much better than polyester does - it is just a mechanical grip and, somehow, epoxy does it better.


For building, we are not mixing things.


So, in my mileage, this is nota tale. And yours may vary.


PS For what sticks to what I can recommend Louis Burton's video from yesterday. (boat Bureau Vallee, VG)


Whoever thinks he used polyester, please raise your hand.

Yep, I was referring to the "Bad Luck" banana myth.

But since we're on the ripening subject. Cavendish is among the most durable and slowest to ripen. So, if we can't find a cure for the pathogen, we will have an even shorter ripening time with whoever our new banana overlord is.

Banana marmalade sounds great

define "much better." that’s where the old wive's tale falls apart, but the bond doesn't.

I'm repairing, building and installing

One thing is for sure, at this stage in my Boat building life, I certainly don’t need to watch a YouTube about how to bond and laminate anything. So you could fill me in on the main point

Re: Old Wives Tales

I thought the “Bad luck and bananas” connection was from loadingthem on ships, allegedly tarantulas and venomous snakes resided in the bunches and were a problem to both the labourers …and the ship crew once at sea.

Re: Old Wives Tales

I don't know about the snakes, but my dad worked on the docks for a while, in San Pedro, CA. He did report the tarantulas, but the way he did made it sound like the guys unloading the ships were not very concerned about them. They're big and fuzzy, but not known for having bad venom, like say, a black widow (red spot on abdomen) or a red-back (looks like a black widow, but with the red on the other side.

I had several black widows on the boat when I first launched.

They were mostly concentrated up in the anchor locker area.

Thankfully, I went out to anchor immediately and they stayed on deck where there was a nice breeze hunting for insects at night, which never came because I was out at anchor. They died off within a week or two.

You mentioned the ripening earlier. There's a theory that the ships carrying bananas were hurrying to get them to port before they ripened.
In the rush, many accidents happened, and this may have led to the "Bananas are Bad Luck."

I know that every fisherman considers bananas bad luck to have on their boat... I have no idea where that comes from.

Re: Old Wives Tales

Fishermen here in Australia have a few suspect stories like “ prawns left in baskets on deck in bright moonlight will go bad” they call it Moonstruck and actually do cover the iced prawns with tarps.
Another yarn is “ Netfire”, some never trawl when the phosphorescence lights up the net when they shoot away and I’m on the fence about this one too. I’ve seen the netfire often enough, that’s real BUT they trawl out to the 100 fathom line…. Would phosphorescence be active at those depths…. I have a doubt.

Re: Old Wives Tales

Chotu,


let an, not soo old, wife chime in here :-)


regarding Silicone as sealing compound on board.

Did you ever get a spec of it under an orbital sander when preparing some surfaces for painting?



Even when you try to clean well with silicone remover before painting, it can turn out to be a nightmare.

Be prepared for lots of pinholes on the surface to be painted.



That is the reason why boat builders hate it. It's not that it's an inferior sealing compound.
Other compounds based on polyurethane don't have this issue.

Can't say I have experienced that. I'm a butyl tape guy myself, but there sure is a lot of misinformation about it out there

Bananas will make other fruit ripen ie a hard avocado will quickly ripen if placed in a paper bag with a ripe banana.
That is because of the gas given off by the banana stalk.. if you want your bananas to last longer wrap the stalks off in plastic to seal the cut ends.

Thanks for that info Boatman61, that explains why some supermarkets stock bananas with the ends coated/dipped in red wax or wrapped in adhesive tape… I thought it was just a marketing ploy. TIL!

There is now a whole science surrounding transporting and ripening bananas. I recall a vigorous discussion among some industry folks, arguing over tenths of a degree. Basically, they will keep for 28 days at 13 C. To ripen, the temperature is increased to 18.3 C and ethylene gas is admitted. To stop the ripening at the desired point, the gas is flushed and the temperature is dropped back to 13 C. Bagging in PE helps by reducing oxygen. The correct temperatures are critical, and a one degree error can ruin a cargo.

Re: Old Wives Tales

I've gone fishing with some guest fishing people on my fishing boat, who discovered bananas in a lunch bucket fixed by my wife. They damn near threw me overboard with the bananas.
So whatever the curse behind it, for some people that is a serious no-no.
Fact or fiction, I don't know, but I don't have bananas on my boat anymore.
