excellent points...large_diver:One issue to consider with drysuits....seals...especially given the $$$$ you are shelling out for the trip. If it were me, I would bring my drysuit....but I might think through options of what to do if a seal lets go.
- bring wetsuit for back-up = more luggage - :-(
- If seals are older, take a pre-emptive strike and have them replaced before the trip
- Zip seals (DUI)
- Perhaps boat has back-up wet suits available for rental
If taking a drysuit, you should take extra seals, a small tube of the glue, and any tools you need to change them. 3-4 hours later they'll dry, and cure overnight. If this is not an option, revisit going wetsuit!
