Lillistone's plans for alby include fourteen A3 sheets of
CAD drawings and a six page
instruction manual. There are two separate editions of the
plans – Imperial and Metric – be sure to choose.
A Boat for Oars, Sail,
and Small Outboard Motor
7ft 7-1/4in x 4ft 2-1/2in
Stripped weight approximately 30kg/66lbs
Alby was designed primarily
to meet the requirements of a high-capacity tender. The
world is full of designs for 7-1/2 foot Praams, and you
wouldn’t think that there was a need for yet another
example of the breed. However, the customer could not find
exactly what he needed, and so a new design was born.

The main characteristics are: -
- Stitch-and-Glue construction from pre-computed plywood
panels. This allows the boat to be built without the need
for a strongback, mold, or full-size lofting. The resulting
structure is clean and un-cluttered, and can be built
in a relatively short time. All components are bonded
with epoxy and glass tape, to produce a stressed-skin
hull with built-in emergency buoyancy;
- High capacity due to the relatively wide hull and the
way in which the chine lines run from high at the bow
and stern down to a very shallow ‘V’ in the
middle of the boat. This maximizes buoyancy and initial
stability, while retaining a deeper ‘V’ fore
and aft to reduce pounding in a chop;
- Two rowing stations to allow for proper trim with different
- External gunwales so that water, sand, and mud can be
easily washed from the boat when she is rolled onto her
side. This system dramatically reduces the labour required
to install the gunwales;
- The bow transom is relatively low in comparison with
the stern transom – this is designed to provide
adequate height for effective mounting of a standard-length
outboard, and to help with tracking under oars;
- Optional sailing rig, including centreboard and rudder
details. The rig is a very simple balanced-lugsail of
generous area – a set-up which gives excellent performance
with minimal complication;
- Emergency buoyancy built-in under the three seating
positions. This volume can be used for stowage of light
articles such as dry clothing.
Thought you might be interested in a few pics I took (very belatedly I must admit) of the sailing rig I added to the prototype Alby 8' dinghy I made to Ross Lillistone's plans.
I have sailed it in 25kts+ & it is so stable that when maximum hull speed is reached, all it wants to do is bury the leeward gunwale & take on water if pushed too hard. Being unsinkable, all you do is keep a little pressure in the sail to keep the boat just moving while bailing it out. Very safe & fun boat for kids!... big or little!
Hope you enjoyed your recent visit to our fair land.
