The Hanse 2021 outline as drawn, dimensioned in meters read from its marked points.

Code

import { HANSE_2021, VesselProfile, type VesselOutline } from "@bosunkit/components/vessel-profile";
import type { ReactElement } from "react";

export const description: string =
  "The Hanse 2021 outline as drawn at 14.6 m, dimensioned in meters read from the points marked on it.";

const outline: VesselOutline = HANSE_2021;

/** Drawing units to the meter: the length overall, from the transom to the bow's tip, is the reference length. */
const perMeter: number = (outline.hooks.bowTip - outline.hooks.transom) / outline.referenceLength;

/** A distance on the drawing, in meters. */
function meters(units: number): string {
  return `${(units / perMeter).toFixed(2)} m`;
}

export default function Drawn(): ReactElement {
  const { hooks }: VesselOutline = outline;
  return (
    <VesselProfile
      outline={outline}
      dimensions={{
        lengthOverall: meters(hooks.bowTip - hooks.transom),
        waterlineLength: meters(hooks.waterlineForward - hooks.waterlineAft),
        draft: meters(hooks.keelFoot - hooks.waterline),
        freeboard: meters(hooks.waterline - hooks.deckAtBow),
      }}

Hanse's Berret-Racoupeau range from 2021 on has an outline of its own, traced from the hull plan Hanse publishes for the 460, the first of the range: a straight sheer rising a little toward a plumb stem with its bow roller, a reverse transom, three hull windows, a low coachroof with its window band, and below the antifouling line the canoe body, the L-shaped fin keel with its bulb aft, the spade rudder and the saildrive. The rails and the shallow-keel option, drawn dashed in the plan, are left out. Hanse states each model's length overall to the tip of the bow roller, so the outline's length ends there; traced at that scale, the hull measures 13.87 m against Hanse's 13.95 m, and the draft 2.27 m against 2.25 m. With the plumb stem, a shorter waterline comes off the stern alone, so the stem stays upright and the stern lifts.

The outline is traced at 14.6 m and listed in VESSEL_OUTLINES as hanse-2021; the kit exports it as HANSE_2021. The 360, 410, 460, 510 and 590 take this outline; the Judel/Vrolijk boats before them, the 315 to the 548, are another range. It is the profile's default. Given a vessel's proportions, the vessel profile stretches it to her length overall, waterline length, freeboard and draft; a particular not given follows the length overall in the outline's proportion.

Three of Hanse's Berret-Racoupeau range from one outline, each stretched to her own length overall, waterline length and draft and drawn to one scale: the 360, the 460 and the 590.
