Phil Thiel was enamored of the canals of England and France and found the slow pace along the waterways, the pauses at the locks, and the proximity of verdant shores not only relaxing but also conducive to connecting to the world around him. Near the end of his 93 years, he designed several boats in the spirit of the canal boats he traveled in every summer for almost two decades.

Escargot Particulars

 

The Escargot, at 18’6″ by 6′, is the smallest of his canal boats and is designed so that almost anyone could build it. The construction couldn’t be simpler and his plans are meticulously detailed, right down to the drip grooves under the windowsills. Construction requires only a few basic tools and minimal woodworking skills. There are only two significant curves to contend with: the transverse curve of the cabin roof and the upward turn at the ends of the bottom. Neither poses a problem when bending the plywood over the forms.

The hull is built upside down. The four bulkheads and two transoms all have affixed to them posts the same height, and when the boat is assembled upside down the posts support her structure and make it easy to level and square. When the bottom is finished, the structure is sturdy enough to be rolled over and set on a couple of level sleepers for the remaining work. A sketch for a galley is offered as a suggested layout for the starboard side of the main cabin, but a more versatile option that provides a fourth berth is to have the port-side dinette/bunk duplicated. If your crew is in the range of 6′ tall, a modification well worth considering is raising the cabin roof by 6″. (The plans include a four-sheet supplement for L’Ark, a version of the Escargot with 6′ standing headroom under the center of a flat roof with straight sloping sides.)

The Escargot draws just 6″, so you can sneak into some very thin waterways. A 2.5-hp outboard will push the boat along at 4.5 knots, and while a bigger motor would help buck a headwind, Thiel designed the Escargot for “sheltered inland waterways” and that is indeed where the boat is most at ease.

Escargot Patterns

 

With a calculated weight of around 750 lbs, the Escargot is not a heavy burden for towing. It’ll draw admiring stares whether on the road or on the water.

The 16 pages of drawings include basic in-structions, dimensions, details, the layout of pieces on each of the 23 pieces of plywood, and the L’Ark supplement.

The storage space on this Escargot was used to add a wood-burning stove to ward of the cold of off-0season boating.

The catwalk added to the cabin roof proved to be a popular perch aboard the BONZO. The bow often allows stepping ashore with dry feet, though in this case , with very muddy boots.

The canal boat wasn't designed to sail, but wit a leeboard (set 36" to starboard) and a mast (set 18" to port) we can rig for silent running without don't interfering with the normal use of the boat.

The Escargot boat wasn’t designed to sail but, equipped with a leeboard and a mast supporting a square sail, it makes for very pleasant sailing on runs and broad reaches.

Just beyond BONZO my anchor was stuck under a log submerged in mid channel. Pulling from this bank and the far bank didn't budge it.

The Escargot provides a cozy nest for overnights in sheltered backwaters.

The single leeboard has deep roots. Howard Chapelle notes: “The single leeboard…was a very cheap and simple off-side centerboard, in effect, which not only required no case but was also out of the way of cargo placed in the hold or on deck. The advantages of the single were so great, particularly in scows carrying deckloads, that the centerboard never replaced it before the end of sail.”

With its minimal draft and ample windage, the Escargot makes a lot of leeway when the wind is on the beam. The leeboard (not in the plans—see “A Leeboard for a Motorboat.”) solves the problem and greatly improves maneuverability by creating a pivot point for sharp turns.
