Survey watch points

Displacement and dry-weight publications disagree

medium risk · unresolved · dimensions

Manufacturer half-load displacement 56,217 lb / 25,500 kg disagrees with BoatTEST and Power & Motoryacht dry-weight figures and with an earlier MBY 23.5-tonne displacement; later MBY and Powerboat and RIB match the manufacturer tonne figure under half-load wording.

Opened GB54 sources do not share one displacement / dry-weight basis.

Manufacturer page (grand-banks-gb54-model-page) publishes 56,217 lb / 25,500 kg half-load displacement. Matching tonne figures appear in 2026 MBY UK (mby-gb54-uk-sea-trial-2026, 25.5 tonnes) and Powerboat and RIB (powerboatandrib-gb54-review, 25.5 tonnes (half load)). BoatTEST (boattest-gb54-2021-test) publishes Dry Weight 51,800 lbs. Power & Motoryacht (power-motoryacht-gb54-2020) publishes Displ. (dry) 47,400 lbs. Earlier MBY (mby-gb54-build-quality-review) publishes 23.5 tonnes.

Canonical research keeps manufacturer half-load on displacement_lb_min / displacement_lb_max, leaves dry_weight_lb unpublished in missing_fields, and records displacement_lb_min, displacement_lb_max, and dry_weight_lb in conflicting_fields. Do not invent a midpoint across load states.

Confirm whether the surveyed hull’s published figure is half-load displacement or dry weight before comparing tables.
Do not average manufacturer 56,217 lb half-load with BoatTEST 51,800 lb dry or Power & Motoryacht 47,400 lb dry.

LOA, beam, fuel, and air-draft publications disagree

medium risk · unresolved · dimensions

Manufacturer GB54 page LOA/beam/fuel disagree with BoatTEST, Power & Motoryacht, and an earlier MBY review; air draft is unpublished by Grand Banks while editorial bridge-clearance figures also disagree.

Opened manufacturer and editorial sources do not share one LOA, beam, fuel, water, or air-draft set for the V-Warp GB54.

The current manufacturer page (grand-banks-gb54-model-page) and matching 2026 MBY UK trial (mby-gb54-uk-sea-trial-2026) publish 58'0" / 17'7" / 925 gal. BoatTEST (boattest-gb54-2021-test), the 2022 MBY review (mby-gb54-build-quality-review), and Power & Motoryacht (power-motoryacht-gb54-2020) publish 59'5" / 17'6" with 898 gal fuel (and P&M water 290 gal). Powerboat and RIB (powerboatandrib-gb54-review) publishes 18.41 m LOA and 6.20 m air draft against BoatTEST bridge clearance 20'8".

Canonical research keeps manufacturer LOA/beam/fuel/water, records these paths in conflicting_fields, and leaves air_draft_ft in missing_fields (legacy 18 ft unsupported). Verify the hull’s published datum set before planning.

Confirm which LOA definition the surveyed hull uses (platform/pulpit inclusion) before berth planning.
Do not average manufacturer 925 gal fuel with BoatTEST/P&M 898 gal figures.
Treat air draft as unverified for marina bridges; manufacturer omits it and editorial clearances disagree.

Optional Volvo IPS package publications disagree

medium risk · unresolved · documentation

Current Grand Banks GB54 page lists optional twin Volvo IPS 800S at 600 hp each; Power & Motoryacht and Powerboat and RIB instead publish optional IPS 950 (P&R at 725 hp each). Keep unresolved.

Opened GB54 sources disagree on which optional Volvo IPS package applies.

Manufacturer page (grand-banks-gb54-model-page) publishes 2 X Volvo IPS 800S @ 600hp. 2026 MBY UK (mby-gb54-uk-sea-trial-2026) lists IPS800 with the shaft options. Power & Motoryacht (power-motoryacht-gb54-2020) publishes optional Volvo Penta IPS 950. Powerboat and RIB (powerboatandrib-gb54-review) publishes 2 x 725hp Volvo IPS 950.

Canonical research keeps manufacturer IPS 800S @ 600hp on engine_options.volvo-ips-800s-600 and records that path in conflicting_fields. Confirm the surveyed hull’s actual IPS designation before planning draft or performance for the pod option.

Confirm the installed IPS package (800S vs 950) and rated hp from builder paperwork / engine plates before accepting published performance or draft for that option.
Do not treat IPS 800S @ 600hp and IPS 950 @ 725hp as interchangeable.

Can a Grand Banks GB54 clear Fort Lauderdale bridges?

Published air draft is 18 ft hardtop. 17th Street closed is about 55 ft. SE 3rd Avenue is about 16 ft. Manufacturer numbers, not a listing photo.

What draft does a Grand Banks GB54 need in Fort Lauderdale?

Manufacturer published draft is 4.25 ft. We keep 1 ft under-keel on the canal overlay. Victoria Park laterals are about 4.5 ft. Harbor Beach is the deep-water conversation.

Grand Banks GB54 LOA and beam versus canals?

58 ft LOA and 17.583333 ft beam. Skinny isles such as Fiesta Way are limited by beam and fixed-bridge clearance.
