Linssen 470 Grand Sturdy
The published record on this model and what owners report, with the
questions worth asking while a boat is still a listing. This page covers the model.
Every boat still needs its own homework.
A rare, heavily-built Dutch steel displacement cruiser with low air draft and good range, well suited to the Loop, but Volvo parts/service and possible Euro electrical standards are the watch-items.
The Linssen 470 Grand Sturdy is a low-production, steel-hulled Dutch displacement motor yacht with a full keel, skeg-hung rudders, and a deliberately low-profile deck layout. It is an uncommon model. Detailed owner threads and published boat tests for the 470 specifically are scarce, so much of this profile is extrapolated from brand-level discussion, sibling models (410/430/500), and the Volvo TAMD41 engine family; treat figures as starting points to verify on the specific hull. Its low air draft, shallow-ish draft, and large fuel capacity make it attractive for the Great Loop, while US-market examples (only about 15 Linssens were imported to the US around 2002) raise questions about electrical standards and Volvo service support. One US listing shows twin Volvo Penta TAMD-41 diesels.

Air draft
CLAIM
Low-profile deck design keeps air draft down
The Grand Sturdy line deliberately favors low air draft: the helm sits on the aft deck rather than a flybridge, keeping the superstructure low. US listings cite roughly 15 ft bridge clearance versus a European-spec figure around 3.06 m, the difference likely being US-fitted radar, antennas, or a mast. You must measure the actual highest fixed point on the specific boat and identify what folds or unsteps.

Range & fuel
CLAIM
Large steel fuel tankage supports long displacement-speed legs
US boats carry roughly 495 gallons in two metal tanks (European spec around 1,760 L). Combined with displacement-speed cruising, this gives generous range, though no model-specific fuel-burn or range figure could be confirmed. Measure/verify actual tank capacity and condition on the specific hull.

CONTEXT
Expect displacement-speed burn at the high end of TAMD41 forum figures
This is a displacement hull cruising roughly 7–8.5 kn (max around 9.4 kn), so it will not exceed hull speed. TAMD41 forum burn data (e.g. 6 kn ~8 L/h, 8 kn ~14 L/h single-engine on lighter boats; ~2 nmpg at 8 kn on a 44,000 lb trawler) come from boats lighter than the ~25-ton 470, so treat them as optimistic lower bounds rather than numbers for this model.

Systems
QUESTION
Is the electrical system 120V/60Hz, or a European 220V/50Hz setup?
European Linssens are commonly wired 220V/50Hz, which complicates shore power and onboard AC equipment on US Loop docks. Owners repeatedly flag this as the single biggest headache on imported examples. A US-market boat may have been converted, or may not have been fully converted.

Trawler Forum, "Where is no go for this?"
Your move: Get written confirmation of the shore-power voltage/frequency and inlet rating, and have a surveyor verify whether any 220V/50Hz equipment remains onboard.
Handling & hull
CONTEXT
Steel displacement hull with full keel and skeg-hung rudders
The 470 is a heavily built steel yacht with a full keel and protected, skeg-hung rudders. She's robust, directionally stable, and well-suited to the Loop, but heavy (dry weight ~53,000 lb / ~25 t displacement) and slow to accelerate. A steel hull also means hull/plate and bilge corrosion inspection is central to any survey.

Reading the boat
QUESTION
What is the steel hull's plate thickness and corrosion history, especially at the bilge and waterline?
Steel hulls are durable but their condition hinges on coating integrity and corrosion control; US surveyors may be less familiar with steel. The bilge, waterline, and areas under tanks are the usual trouble spots.
src:
Trawler Forum (steel-hull caution in Linssen discussion)
Your move: Commission a surveyor experienced with steel hulls, including ultrasonic plate-thickness readings, and ask for the vessel's documented corrosion/coating and anode history.
CONTEXT
Rare model with limited US presence
The 470 is low-production and only about 15 Linssens were imported to the US market around 2002, so comparables, parts familiarity, and model-specific knowledge are thin. Budget extra time for parts sourcing and finding mechanics/surveyors familiar with the brand.
