Deano2:
I am heading to the Galapagos in November 2005 (poor me). As the water temp is 60-70 (15-21 C) can anyone recommend whether they have dived there in that season and whether it's preferable to dive dry in a Trimalite suit or should we dive in wet suits? Thanks for the help !
My various trips to the Galloping Pogos in November & December have logged temperatures between 74 and 81 degrees. I am not sure where your chilly numbers came from, but that might cast some doubt upon some of the other information from that same source.
I have been in this temperature water in nothing less than a polar fleece. It was not my choice, it was all that I had, and it wasn't something that I relished- just that for three dives a day, it was survivable. I say this just to paint a picture of how insensitive to cold that I am. This question, as to your resistance to cold, is one that you leave open.
I prefer to dive in those temps in my 3/5 from
www.wetwear.com . I give their website because it's the single best manufacturer of custom suits that I have found. Don't forget a dive beanie!
I have seen dry suits used in these temps and above quite successfuly with no insulating undergarment.
Another important criteria that you leave open is your intended dive frequency. Also- a four dive a day program from a land based operation will cause much less overall wear and tear on your body's furnace than a live aboard. Ships, even while you believe you are resting aboard them, require a lot of compensating energy from a body un-used to the rocking and motion, much less the everpresent a/c and dry humidity levels.
Many considerations.
What is your resistance/recovery?
How many dives per day?
What is your off-gassing environment?
And finally, the G is the last place one might take a dry-suit along without intimate familiarity in its operation and issues inherent in doing backroll entries and small boat surface recoveries.
