General Nautical Terminology | Nautical Topics | Navigation | Parts of a Boat

Bow

The forward part of a vessel.

The bow includes the hull structure at and around the vessel’s forward end, where the port and starboard sides converge or are joined by the stem. Its form varies with intended speed, displacement, seakeeping, cargo or accommodation needs and construction method.

Some bows are fine and wave-piercing, others full or bluff, and some ships have a submerged bulbous bow designed for particular operating conditions. Anchoring and mooring equipment is often fitted forward, but the term identifies location rather than a guaranteed shape, hydrodynamic effect or equipment layout.

  • Bottom-Up vs Top-Down: Pilotage Plans That Work
    Bottom-up or top-down? After several practical courses with skippers trained elsewhere, I saw the same pilotage problems: plans too long to read or too thin to protect the boat. Here’s how to choose a format, avoid left/right flips, and build a cockpit-ready plan that works by day and at night.
  • Fastnet ’79: Safety Lessons We Still Use Today (and the night it all went wrong)
    Fastnet ’79 changed sailing. A sudden August storm, five yachts lost, lives cut short—and safety rules rewritten. We’ve pulled the lessons skippers still use today: heavy-weather choices, DSC/MAYDAY drills, horizontal recoveries, and practical prep you can do this week.

  • From zero to a family Mediterranean charter: a clear path you can follow
    Your family Med sailing holiday is closer than you think. Pick your route: • Fast-track: 8–10 weeks • Balanced: 3–6 months • Steady: 6–12 months Get the right tickets early. Day Skipper, ICC, and VHF SRC. Croatia checks VHF hard, don’t risk a ruined check-in. Start in a flotilla or hire a skipper for day one or two, then build to bareboat confidence. This guide lays out the steps, the timelines, and what “ready” really looks like.
