Cruising trimaran

On this page

The cruising trimaran outline as drawn, dimensioned in meters read from its marked points.

Code

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

export const description: string =
  "The cruising trimaran outline as traced at 15.98 m, dimensioned in meters read from the points marked on it.";

const outline: VesselOutline = CRUISING_TRIMARAN;

/** 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),
      }}
    />
  );
}

The cruising trimaran outline is traced from YACHT magazine's side elevation of the Neel 52, a trimaran of 15.98 m: the hulls as the drawing paints them from the side, with a stepped stern and a plumb bow, the deckhouse with its saloon windows and raked windscreen, the hardtop reaching aft over the open cockpit on its post, and the hull window. Under the boot stripe are the canoe body, the fin keel, the saildrive and the spade rudder. The rig, the bowsprit and the flag are left out. The drawing marks no waterline, so the trace sets it at YACHT's draft of 1.90 m above the keel's foot; the transom is immersed, so a shorter waterline comes off the bow.

The outline is traced at 15.98 m and listed in VESSEL_OUTLINES as cruising-trimaran; the kit exports it as CRUISING_TRIMARAN. The vessel catalog's trimarans, three models, take this outline. 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.
