Charismatic megafauna, and also some very charming regular-sized fauna

In the unlikely event that a visitor down here should get tired of being in the mountains, I suppose that visitor could spend time on the water.  That choice would put the lucky visitor in some very good company.  

Like, this jostling, snorting herd of South American sea lion males:

Or this resident colony of gentoo penguins, third-largest species in the world (after Imperial and King).  About 60 individuals are here year-round:

Or these stragglers of a seasonal colony of migratory Magellanic penguins:

The standard means of approach to these critter colonies are big cruisey catamaran or little bouncy zodiac.  Sure, you can spend the day with 100 of your closest friends slugging wine and chomping on pastries on the catamaran.  But wouldn't you rather get up close and personal?  Choose the tiny, cold boat with less draft, every time.
