We are working on a seastead design that will have a 40 by 16 foot living area above the water. There will be 4 foot wide columns that are about 20 feet long going out from from the 4 corners of living area and down into the water at 45 degrees, which half of each column under water. The bottoms of the floats will make a rectangle about 44 feet wide and 68 long. From the bottom of each column there will be 2 cables going to the adjacent corners to hold it in place. There will also be a cable making a rectangle between the bottoms of all the floats so we have some redundancy in case one cable breaks. The seastead is about 30,000 lbs I think but this is NOT a normal boat hull shape, it is more like a tiny oil platform as far as drag. We expect to use 2.5 meter diameter propellers on two submersible mixers and solar power to move at around 1 MPH plus any help from using eddies. In other prompts I look at safety against sinking and backup propulsion options. Here I want to look at general safety things. Here is our list of general things so far: SOLAS-approved life raft. EPIRB: Emergency Position Indicating Radio Beacon (406 MHz) Fire extinguisher. Bilge pumps in each of the floats. These might be manual or automatic. Medical kit: Enhanced offshore medical supplies Communication redundancy: Along with starlink we will have VHF, and phone with satellite plan. Navigation lights Collision avoidance systems We expect that our design with many dupex stainless steel parts will have an excellent radar reflection but we will check this and if it were not so have a dedicated radar reflector. Personal Flotation Devices (PFDs/Life Jackets): One for each occupant, including spares, with reflective tape and whistles attached. Distress Signals: Flares (handheld, parachute, and smoke), plus a signaling mirror or laser flare for visual distress signaling. Man Overboard (MOB) Equipment: Throwable flotation devices (e.g., life rings), MOB recovery ladder or sling, and personal locator beacons (PLBs) for individuals. Emergency Rations and Water: Waterproof storage of non-perishable food and potable water sufficient for at least 72 hours per occupant. Backup electrical power. Our solar power system will have at least 2 separate systems. Multiple GPS and Compass Sea Anchor / Anchoring - For normal use we expect to use dynamic positioning but will have anchor and sea anchor also Safety Harness Sensors for monitoring pressure and water in floats and sounding alarms if there is a problem Backup propulsion methods: kedging with sea anchors or regular anchors in shallow, dinghy with 3 HARMO motors, kite stacks Weather Monitoring AIS Inside the main floats/legs there will be 7 floatation bags in case there is a leak Personal Locator Beacons (PLB) Telemedicine Capability - Satellite-enabled consultation service with medical professionals Regular cleaning and inspections of the structure Watch schedule Pyrotechnic Flares Smoke detectors / Carbon Monoxide Detectors - no gas onboard only electric cooking Toolkit Search light Radar Depth sounder Documentation of safety plans Maintenance Logs: Document inspections for critical systems (floats, cables, propulsion). Are there other general safety items we should have on this list?
