Reconcile an offset-aware longline layout with actual deployed and retrieved hook records without treating spacing arithmetic as compliance.
A quick decision brief for this specific tool
Entered active-mainline length, spacing, start/end offsets and whole actual deployed and retrieved hook records
Offset-aware layout positions, signed deployed-versus-layout difference and not-retrieved count
Reconciles layout and haulback records; it does not choose hook spacing/count or determine whether gear complies
Choose your path
Reconcile an offset-aware longline layout count with actual deployed and retrieved hook records without choosing gear or determining compliance.
Compare the documented active section and offsets with hooks actually deployed.
Enter active length, spacing, offsets and actual deployed/retrieved whole counts.
Sees layout and haulback differences rather than an approximate capacity claim.
Keep deployed and retrieved counts separate.
Review the not-retrieved count under the vessel lost-gear and reporting procedure.
Does not hide missing hooks inside theoretical spacing arithmetic.
Keep fishery-specific active length, gaps, hook/gangion rules and closures current.
Check the exact permit, CFR and agency guide before deployment.
Never treats the layout count as authorization or compliance evidence.
Outputs and checklists are planning aids. Review the linked current authorities and the records, terms, instructions, and requirements that apply to your exact situation before a consequential decision.

Compare an actual hook gap and bait thickness with exact manufacturer-pattern and externally selected clearance records—without deriving hook size from fish weight.
Enter the active-mainline length represented by this record plus the distance from each end to the first and last layout positions. Do not assume this worksheet's wording replaces a regulatory active-gear definition.
Layout count is floor((active length − start offset − end offset) / spacing) + 1. The count describes entered positions only and does not choose lawful spacing, hooks, gaps, or gear.
Actual deployed hooks are compared with layout positions, and deployed minus retrieved hooks is reported separately. Investigate and report lost gear under the applicable procedure.
Updated: August 2026
Compare an offset-aware layout with the whole number of hooks actually deployed rather than relying on line length divided by spacing.
Keep deployed and retrieved hook records distinct so missing gear is visible and can follow the vessel's reporting and response procedure.
Verify current fishery/area permit, active-length and gap definitions, hook/gangion/leader rules, closures, and protected-species measures before deployment.
Record the start and end offsets and use the displayed position-count convention. Different layout conventions can otherwise create off-by-one errors.
Hook count, active length, gaps, branch/gangion construction, closures, soak, protected-species measures, and reporting requirements vary by fishery and current rule.
This record check connects an entered longline layout with actual deployment and haulback counts. It makes offsets and missing hooks visible while leaving gear choice, authorization, and compliance to current controlling rules.
