Design and Construction
Van de Stadt based the GRP Invicta 26 on the Folkboat, and the lineage shows in the low, attractive profile and the full long keel with a transom-hung rudder joined to its after end anchor. Tylers moulded the early hulls, with fit-out handed to a variety of boatbuilders, while later versions were moulded by FI-Craft in Essex and finished by FI-Craft or Salterns Yacht Agency. The construction is solid fiberglass throughout, with iron ballast encapsulated in the keel rather than bolted on. That encapsulation, paired with the robust-looking rudder, gives the underwater body a decidedly traditional and low-maintenance character. Two generations exist: the Mk1 and a Mk2 that bought a little more headroom below anchor.
Rig and Handling
The Invicta 26 is rigged as a masthead sloop, and at 26ft 5in overall with a 20ft 8in waterline, a 7ft 4in beam, and 5,137lb displacement carrying 2,315lb of ballast, she sits firmly in the water. The long keel digs into soft mud rather than bouncing off it, which suits drying harbours, and testers note that antifouling a long keel is far easier than on a bilge keeler. On the helm, she is made for the sea and not for dodging around the buoys; test sailors found she may take a little longer to come round on a tack than a fin-keel boat, a fair trade for the steadiness. Yachting Monthly's used-boat assessment called Invictas sea-kindly, knockabout cruisers that keep a couple or young family safe in all weathers and can embarrass some modern yachts with their speed.
Accommodations
Below, the price of those classic Folkboat lines is limited space. The attractive low profile comes at the expense of interior size, and Practical Boat Owner is blunt that Folkboat-derived hulls carry restricted room down below. The Mk2's extra headroom was the builder's acknowledgment that the Mk1 felt tight. This is a boat for a couple or, at most, a young family without growing children aboard — indeed, the boats are often sold precisely as families get bigger and move up.
Ownership and Refits
The ownership pool tends toward young couples or older sailors sailing without kids on board, which matches the boat's scale and temperament. An inboard engine can be fitted, with an outboard bracket retained only as backup. One extensively overhauled example, Victoria of Rye, received a compact Volvo MD 2010D replacement with raw-water cooling and a heat exchanger to cool exhaust gases, showing the kind of sensible repower a small hull allows. Victoria also retained classic caulked decks, a period detail that survives on some boats.
The Verdict
The Invicta 26 is a small, genuinely seaworthy cruiser with Folkboat soul in a fiberglass shell. She rewards the sailor who values simplicity, a keel that sits firmly in soft ground, and she punches above her length in a breeze. The compromise is the cabin, which is cramped by modern standards and always was.
Pros
- Long-keel, encapsulated-ballast hull that dries out safely and is easy to antifoul
- Sea-kindly, quick for her type, and safe with a couple or young family
- Classic van de Stadt lines with Mk2 headroom improvement available
- Simple construction finished by multiple builders, straightforward to repower
Cons
- Limited interior space from the low profile
- Slower to tack than a fin-keel design
- Often outgrown as families expand
