Q: Why don't you include a BP cuff or pulse ox?
A: On a coastal trip, you're banking on a vital-signs hand-off to EMS within hours, not days. Diagnostic equipment is in the Offshore Kit because that's where you actually need to track vitals over time. Adding diagnostics here would push price and complexity without changing outcomes for most coastal scenarios.
Q: Hydrocolloid dressing — when do I use it vs gauze?
A: Hydrocolloid is a sealed, moist-healing dressing for shallow partial-thickness wounds, blisters, and minor burns — it stays in place for days and lets the wound re-epithelialize. Gauze is for active bleeding, dirty wounds that need irrigation/inspection, and wounds that are still draining heavily. We cover the decision tree in our blog.
Q: Why two emergency mylar blankets?
A: We pack two so you can wrap a patient and put one over yourself or under them as a vapor barrier. The Coastal Cruiser doesn't include a hypothermia bivy because at 12–24 hours from care, you're warming the patient in the cabin, not bivying on deck overnight. The Offshore Kit ships with the bivy approach.
Q: Is this kit FDA-compliant?
A: Yes. Every cleared device is sourced from an FDA-registered manufacturer. The kit is packed under a documented procedure with lot and expiration tracking. Individual cleared devices retain their own labeling and IFUs.
Q: Can I add prescription medications?
A: Not directly through this listing — that requires a physician relationship. Tether Medical (cross-linked at checkout) is our integrated path: virtual consult, prescription if appropriate, third-party fulfillment, and meds labeled to fit this case.
Q: What's covered by a Tether-certified subscription?
A: Annual review of all expiration dates, automatic shipment of replacements before items expire, freshness certificate to keep onboard, and eligibility for prescription augmentation.
