Your hull. Visible.

SailEdge™ by SailrScience assigns the best-fitting hull from the reference library by certificate best fit — shown for your review before any number leans on it.

Assigned

The engine assigns the best-fitting hull family from your certificate — Ballast, Form, or Hybrid.

Cross sections inside the hull outline. Sheer, waterline, keel.

Review

Confirm the assignment before the Edge Map — or change it as a declared scenario.

Assigned and Shown

The hull that matches your boat — assigned, and shown.

The Boat tab carries the best-fitting reference from the R16 hull library of 52 Delft Systematic Series reference geometries (IGES-derived), assigned by certificate best fit — with the ranked candidates alongside for your review. Change it if you choose: an override is a declared scenario, never a silent change of truth.

The assigned hull appears as a profile card — cross-section station frames inside the hull outline, sheer line, waterline, and keel spine all visible. You see the shape before any number leans on it.

Three Families

Every hull carries its stability differently.

Ballast

Deep keel, narrow waterplane. Stability predominantly ballast-led across the supported heel range.

Form

Wide beam, strong waterplane. Stability carried by hull form, strongest at low heel.

Hybrid

Stability from beam and ballast in balance.

Then Open the Edge Map

The Edge Map starts with the hull.

If the hull family is wrong, the delta is wrong. Hull Shape puts that decision in front of you before you run the study.
