Jopiči

[Rok-11]

Za začetek je treba ločiti rešilne jopiče in PFD-je (Personal Flotation Device).
Tile zadnji so večinoma športni jopiči, ki se jih dobi za surfanje, wake, kajak, ipd - in imajo precej manj vzgona, ter ne držijo nezavestnih ljudi.

PFD - Personal Flotation Device - je sinonim za rešilni jopič ali drug pripomoček, namenjen da osebo obdrži na vodni površini.

So pa različnih kategorij in namenov:

USCG PFD Categories - Types I-V

USCG and State Law Enforcement agencies require and/or recommend different Types of PFD's for different applications. Make sure you are aware of the requirements for your state before you select your PFD.

Most adults need an extra 7 to 12 pounds of buoyancy to keep their head above water. Below is a list of minimum buoyancy for each type of PFD.

... (tabela se koliko funtov se ne prenese lepo na forum in je na povezavi) ...

• Type I - Offshore Lifejacket
  
  
  This PFD is designed for extended survival in rough, open water. It usually will turn an unconscious person face up and has over 22 pounds of buoyancy. This is the best PFD to keep you afloat in remote regions where rescue may be slow in coming.
  
• Type II - Near Shore Buoyant Vest
  
  
  This "classic" PFD comes in several sizes for adults and children and is for calm inland water where there is chance of fast rescue. It is less bulky and less expensive than a Type I, and many will turn an unconscious person face-up in the water.
  
  
• Type III - Flotation Aid
  
  
  These life jackets are generally considered the most comfortable, with styles for different boating activities and sports. They are for use in calm water where there is good chance of fast rescue since they will generally not turn an unconscious person face-up. Flotation aids come in many sizes and styles.
  
• Type IV - Throwable Device
  
  
  These are designed to be thrown to a person in the water. Throwable devices include boat cushions, ring buoys, and horseshoe buoys. They are not designed to be worn and must be supplemented by wearable PFD. It is important to keep these devices immediately available for emergencies, and they should not be used for small children, non-swimmers, or unconscious people.
  
• Type V - Special Use Device
  
  
  Special use PFDs include work vests, deck suits, and hybrids for restricted use. Hybrid vests contain some internal buoyancy and are inflatable to provide additional flotation.
  
  
• Inflatable Life Jackets
  
  
  Inflatable life jackets rely on inflatable chambers that provide buoyancy when inflated. Uninflated, inflatable life jackets are less bulky than inherently buoyant life jackets. Inflatables come in a variety of U.S. Coast Guard-defined performance types. The specific type of life jacket is determined by characteristics such as its amount of buoyancy, its in-water performance and its type of inflation mechanism. To understand the details of a life jacket, read the life jacket label and owners manual, and consult your dealer or retailer if necessary.
  
  All inflatables contain a backup oral inflation tube (which also serves as the deflation tube).

Mimogrede, napihljivi rešilni pas, ki smo jih imeli na ISAF tečaju za preživetje na morju, so imeli ovratnike (offshore ali ocean tip) in bi morali obdržati nezavesnemu glavo v položaju, da lahko diha.

Hoj!

Marjan Tomki vam je lepo napisal in še s slikami prikazal za kaj gre. Torej v čem je problem? V čem zavajam?

Dajte fantje, bodite resni. Na tem forumu je polno nergačev, ki vse vedo.

Bom naročil adminu, da pobriše moj račun.

Vsem skupaj želim mirno morje.

Hvala vsem za obširno razlago. Verjetno bom ostal pri Type II opremi.

Če si že razmislil, kje, kako in v kakšnih okoliščinah (pri kakšnih dejavnostih) jih boste uporabljali, in se ti iz tega izide na tip II (obalni), je to OK.

Na povezavi, ki sem jo dal zgoraj, je tudi razdelek 'usage and advantages', torej zaradi katerih lastnosti je kateri tip primeren za katero vrsto uporabe.

In niso bistveni tam napisani odgovori (ti se s časom spreminjajo) - bistvena so vprašanja, ki si jih je treba postaviti, ko izbiraš. Morda bo koga presenetilo kaj, kar je tam napisano (in drži), na primer


How much 'extra lift' you need in water is determined by body weight and fat, lung size, clothing and water conditions (rough or calm). In general, the more physically fit you are, the more 'lift' you need


O tem najbrž ne bi škodilo tudi večini nas ostalih malo razmisliti.

Ravno glede na namen, ki ga hočem doseči sem se odločil za Tip II. Želim, da otrok v slučaju padca s čolna lahko v vodi diha, ne glede na stanje v kakršnem se bo po padcu znašel. Torej prva je varnost, potem pa udobje in zabava.

Zase in za odrasle potnike imam tip 3, za otroke pa obvezno tip 2.
Zdi se mi neodgovorno, ko vidim, da otroci na čolnih nimajo oblečenih jopičev. Govorim predvsem o odprtih čolnih, kot so gumenjaki in manjši gliserji.

[cibro]

Ne vem v kakšnih razmerah plujete samo ali vam otroci kar padevajo ven iz čolnov ali kako?
Ne štekam.
Če mulotu 10 let rečem da sedi spredaj na blazinah tam sedi kot pribit. in ob normalni vožnji ne more ven padet.
Mirno morje in lep dan plovbe seveda.
Če pa so neke extremne vožnje skakanje po valovih in plovba ko je slabo vreme potem ja. Drugače pa ne vem, je pa seveda vse možno najbrž se kaj opleta med plovbo in kdo žokne dol samo meni vsaj po izkušnjah se nam je to prej zgodilo na jadrnci kot na gumenjaku.
Morda na manjšem gum., ki na polnem plinu res poleti čez val in bi znalo otroka skipat samo to je pa že malo neprevidnosti.

Tudi z avtom se ne zaletiš mogoče nikoli, pa imaš vsaj otroka vseeno vedno privezanega, ni tako?
