I’ve found that it takes about three weeks to decompress from your former lifestyle, and about six or seven weeks to fully accept/adopt the simpler way of living...at least while sea kayaking.
Before embarking on such trips, my wife and I discussed the possibility of us getting into arguments or having conflicts because of the disruption to our ‘normal’ lives, additional stressors, and living so close to each other. Made those very rare moments less traumatic.
Only you can make the call...some people wouldn’t consider it on anything less than a million dollar boat
