⚠️ Important Disclaimer: These figures are educated estimates only. A seastead with tension leg anchoring is a novel vessel/structure type not yet explicitly addressed in most maritime regulations. Actual fees may vary significantly based on: (a) negotiations with local port authorities, (b) environmental impact assessments that may be required for semi-permanent anchoring, (c) interpretation of whether the seastead is classified as a "vessel," "floating structure," or "offshore installation," and (d) changing visa and cruising permit policies. We strongly recommend contacting local authorities and a maritime lawyer before planning any seastead anchoring. Costs shown include estimated cruising permits, anchoring/mooring fees, visa/permit fees for 2 adults, and basic administrative costs. They do not include fuel, provisioning, insurance, helical screw installation/removal, or unexpected regulatory charges. All values in USD.
