Silver Origin and use of Full Face Snorkel Mask

[nast]

Is it allowed to use a full face snorkel mask on a Galapagos cruise, Silver Origin?

I'm reading this is prohibited. 

 

My wife only snorkel with this kind of mask. 

 

The problem apparently is CO2 built-up, but this is mainly the case with some older and cheaper models.

The newer models have a design which keeps CO2 levels safe.

When I was on Silver Explorer last year, full face masks were not allowed for scuba diving for the reason you state, but it wasn’t mentioned in relation to snorkelling.  I’m sure I saw at least one passenger using one. You probably need to discuss with your expedition leader.

My full face snorkel mask is a rather different design, and consequently has no CO2 issues - not the typical 'tube out the top' style at all.  I could use a pound of Vaseline and never get a decent seal around my mustache, so it's full face or nothing.

 

Here's one similar to what I have.
