Hi 
Seriously consider a good antenna DXing barefoot is nigh unto cruel and unusual punishment, IMHO thus denying you your Constitutional Rights under 8th Amendment if the US Constitution as well as Section 12 of the Canadian Charter of Rights and Freedoms 

I suggest one of the newly arrived SDR Accessories on eBay, Amazon, AliExpress, etc., the MLA-30 Magnetic Loop Antenna 
https://www.ebay.ca/itm/MLA-30-Loop-Antenna-Active-Receiving-Antenna-100kHz-30MHz-for-Short-Wave-Radio-/283529483468   A $30 Antenna that plays in the league as the Big Guys W6LVP, KR1ST, Wellbrook, MFJ, etc..  
While you're at it consider a $25 Mini Whip as well

MLA-30 Loop Antenna Active Receiving Antenna 100kHz - 30MHz for Short Wave Radio 

The MLA-30 loop antenna is a popular broadband antenna

  • It is an effective antenna for short-wave listeners (SWL) and amateur radio enthusiasts (HAM) to receive medium-wave and short-wave in the limited living area of the city
  • The MLA-30 loop antenna is easy to install and can be easily installed on balconies, rooftops, and other small, compact, low-profile installations without worrying about neighbors and property opposition
  • Another advantage of the MLA-30 loop antenna is that it is directional
  • By rotating the antenna so that the antenna's dummy point is aligned with the interference signal, the specific near-field interference can be minimized  
 




The MLA-30 is such an antenna. The MLA-30 is a toroidal magnetic antenna.
        The MLA-30 loop antenna is a popular broadband antenna. It is an effective antenna for short-wave listeners (SWL) and amateur radio enthusiasts (HAM) to receive medium-wave and short-wave in the limited living area of the city. Frequency coverage: 100kHz to 30 MHz. Excellent directionality can help you reduce noise and improve the signal-to-noise ratio, and can dig out weak signals that are overwhelmed by noise when conventional antennas are received.

Details of the MLA-30 loop antenna:
Do not connect it to the transmitter as it will cause the preamplifier to be damaged.
Local radiation noise suppression up to 30 dB compared to long-haul antennas
8-shaped patterning provides deep dummy points to further reduce interference
USB power supply, convenient to take power. Self-contained feeders simplify the installation process.
Simple structure, easy to install to the balcony, rooftop, and other locations.
No manual adjustment required
Install low-key, no need to worry about neighbors and properties.
Modular design, easy to install and maintain.
Stainless steel ring vibrator, easy to install and easy to maintain.
Rainproof enclosure for long-term fixed outdoor use.
Main coverage: 100kHz to 30 MHz

note: Need to prepare a PVC sheath tube for support, any diameter, need to pay attention to the need to have a certain strength, any community hardware store can buy. You can also use existing bamboo poles, wood poles, etc., and be careful not to use metal rods.
Note: Please allow minor errors due to manual measurement.
Item color displayed in photos may be showing slightly different since monitors are not calibrated same. 

Package Contents:

I disagree.

Out on open deck, I've found on several cruises (number seven comes up to two weeks) that the ships have been amazingly quiet.  Obviously you're not gonna be trying inside a steel-plate enclosed cabin/stateroom/inside lounge, but be exposed outdoors... with no problem using a decent hand-held such as the Tecsun PL-380.

The Big Challenge is avoiding close range lighting (so seeing can be interesting at night if you're trying to take notes) and sheltering from wind for comfort, which can be a nuisance even in warmer climes.

Walt Salmaniw from Victoria, BC has proved all this on several occasions... including stuff I experienced during late evenings north of NZ heading from Auckland to Tonga and beyond.

The 380 off the coast of South Africa/Namibia provided outstanding reception up into the Mediterranean and Middle East, along with what at the time was a mystery in Chinese on 1098... which turned out to be CNR 11's 1000kW tx from Golmud.  It helps that South Africa isn't exactly a big AM user.

Identifying what you're hearing is going to be interesting but, hey, that keeps the grey cells alive.  Explaining to other passengers is the same as on dry land -- crew members can be inquisitive... late-night visits to a higher, exposed deck can be checked! 

And even mid-afternoon snoozing with an extended antenna poking through the deck railing earned me a visit from a Senior Officer to prove I wuzn't 'fishing' over the side!  I kid you not... he admitted his wife (so that's how Senior he was) had reported me.

You'll hear tons... enjoy it all.
