General Concept
The original design assignment for this vessel was to create a robust and classic
displacement type long range steel trawler for a couple with guests,
having two equal staterooms - the purpose of the
vessel being long coastal cruises as well as ocean
passage making.An additional requirement was to have
a generous but secure and comfortable flying bridge, yet
to stay within the height limits for travel on the canals of Europe. As it turns out, this was
quite a challenge, but the resulting layout is excellent.
The primary canals of France ( Freycinet Standard) have a limiting air draft of 3.50 meters (11' - 5.8"), a limiting water draft of 1.80 meters (5' - 10.9"), and a limiting beam of 5.0 meters (16' - 4.9").
The main German canals have a limiting air draft of 5.25 meters (17' - 2.7").
In the half load condition, with Bimini top, mast, poles and exhaust stacks down, the
Vagrant 49 has approximately 10' - 9" air draft,
leaving several inches to spare even in the French
Canals, opening the door to nearly all of the European
canal system.
Hull, decks and cabin are steel, with all scantlings according to the ABS Rule. Plating, framing and other internal structures
have been detailed for NC cutting, including integral water and fuel tank faces, engine girders, etc.
The house top and flying bridge coamings are cold molded
plywood, laminated into a single large structure then
sheathed in GRP.
The Vagrant 49 makes use of Paravanes for roll stabilization. The
paravane rig is detailed to be economically built of aluminum pipe. In all, the whole design is intentionally quite simple, so should be economical to build, to maintain, and to travel with.
Variation on a Theme...
We also co-developed the same design without
the flying bridge: the Migrant 49.
Migrant has exactly the same hull form and interior
layout, but the flying bridge is deleted in favor of
keeping a lower profile with less overall windage.
Another slight difference is the use of a visor forward
and a faceted forward face on the pilot house. Other
aspects of these two designs are identical.

Vessel Particulars
Displacement will vary approximately from 51,500 lb in the 10% load condition to 62,500 lb in the 100% load condition. Other particulars are:
- 49'- 4" Moulded Length Overall
- 13'- 7" Moulded Beam
- 46'- 8" WL Length, Half Load
- 5'- 2" salt water Draft, Full Load.
Power & Range
The engine specified is a John Deere 6 cylinder diesel, which produces 175 hp at 2,400 rpm in the M-2 rating. The engine is mated to a Sabb controllable pitch gear using a 3:1 reduction to drive a Helseth three blade 34" CP propeller.
The "cruising speed" for long range voyaging with this hull is assumed to be around 8 knots. Theoretical hull speed is around 9.5 knots, however due to having relatively light displacement the hull should reach close to 11 knots with the planned horsepower.
Using 1,200 USG of fuel and keeping a 15% reserve, the Beebe algorithm shows range in the average load condition to be around 3,150 NM at 7.5 knots.
Exterior Arrangement
The aft deck, side decks, and interior pilot house deck are all at
one level. There are two exterior water tight doors entering the pilot house. The side and aft decks are surrounded by substantial bulwarks, and the fore deck by a toe rail. All decks are surrounded by lifelines, with welded steel pulpits forward and aft.
Right aft in the cockpit area is an aft-facing seat.
Wing plates are arranged to flank the aft deck, and allow the
cockpit seating area to be easily enclosed by screens and / or vinyl - canvas, depending on the season.
A ladder on center leads up from the aft deck and into the well-protected
flying bridge area above the owner's cabin. The flying bridge is arranged with two long seats
outboard. The whole idea of the flying bridge is
to allow outside enjoyment, accommodate occasional
outside sleeping, and for lounging and dining with a 360
degree view. The flying bridge contains a second helm seat and control station forward. A mast and paravane rig are located just aft of amidships with all control lines operable from within the flying bridge.
The fore deck spans the full width of the boat from bulwark to bulwark. This provides a very large volume within the forward accommodations below. Davits port and starb'd allow placing a shore boat onto the fore deck. A dual capstan horizontal anchor windlass is located forward.
Interior Arrangement
The accommodations are intended to provide comfortable cruising for four people. Deck structures provide 6' - 6" standing headroom throughout. See the links above for a comprehensive view of the interior and exterior layout.
Beginning forward, there is a generous guest cabin, arranged for maximum privacy. The guest cabin has a queen size berth, plenty of shelves and a big hanging locker. A door leads directly from the guest cabin to a combination
head / shower. Another doorway leads aft to the galley and saloon.
The large L-shaped galley is located to starb'd at the base of a spiral stairway. The galley contains a large refrigerator / freezer aft, large sink, and three burner propane range.
In the saloon to port is a large wrap-around dinette and table, sized for six. The intent is that this will be the primary entertainment space. With the full width raised foredeck, the galley and saloon will be light and open and will have unobstructed views to port and starb'd.
At the aft end of the saloon / galley is a spiral staircase leading to the pilot house, and a WT door leading into the
engine room below the pilot house. Access to the engine room is also via large opening hatches in the pilot house soles.
The pilot house has a WT entry door to port and starb'd. The helm station is located on center, and a large bench seat is located to port, aft. There is a narrow table with a drop leaf, allowing occasional meals to be taken there, or just for observing and conversing with the helms-person.
Just aft of the pilot house and below the flying bridge is the
owner's cabin, accessed by a companionway ladder to port, aft within the pilot house. The owner's cabin contains a private head and shower, queen size berth, rather large hanging locker, and wrap-around shelves and storage.
Design Summary
Overall the primary goals for the Vagrant 49
have been to fit two nearly
equal staterooms into a sea-going boat of 15 meters or
less on deck (for the sake of easier ownership and
piloting within the EU). The
layout has worked out very well, and the boat is not at
all crowded. Easy canal cruising throughout the EU is
made possible by the relatively low profile, even though
there is a generous flying bridge...!
If the flying bridge is not important, the
Migrant 49 provides the same layout and hull
form with less windage and better visibility from the
helm.
Design Genesis
Several of our designs share the
same essential source hull type, in this case
derived from the North Pacific
fishing trawlers which operate in all
weathers in the Gulf of Alaska, a place where the
ocean is... well, not so nice. We
refined the fishing trawler hull type to create
a more yacht-like shape and that became the
"Greatheart / Gulliver" series. See
the following links for vessels in the Greatheart series...

Gulliver 46 |
Greatheart 48 | Greatheart 54 |
Greatheart 60
We then modified
the hull to create the "Vagabond"
series which makes use of a proportionately longer waterline
and a more upright stem and transom. Combined, this reduces the
overhangs and increases the WL length to gain more interior space with
less overall hull length. Check out the following links for boats in the Vagabond series...
