Pearl: a gaff, lug or gunter rigged dayboat
Pearl 16, a day sailer or beach cruiser, half-decked, with multichine stitch and tape or glued clinker-over-stringers construction. The hull is of 6mm ply, the deck and cockpit of 5 or 6mm, with centre-board and dagger-board options. The cockpit has various permutations, from deep and open, to reduced volume, through to self-draining, but all with built-in buoyancy. This is a relatively light displacement boat designed for trailer-sailing for a couple of adults with a lightly ballasted hull or for the single-hander with a well- ballasted one.
Pearl, with either a lug main and mizzen, gunter yawl or gaff cutter rig, is beamier, flatter floored, fuller transomed than Apple with the option of lead and water or water ballast. Annie is similar, but 18 foot LOD. See the Apple cutter photos for a similar but smaller version of the rig and general layout. Detailed plans for Pearl - for both glued clinker construction and for multichine stitch and glue, with various cockpit layouts - are available, as well as alternative sail plans - a total of 18 A1 sheets and 26 A4 sheets of notes and keyed detail. A high resolution and detailed A1 PDF study plan of one lug main and mizzen layout and sail plan, plus another of the gunter yawl with general layout and sail plan is £10 or, for two A1 printed study sheets, £13 plus £2 p/p. A small watermarked one without construction detail and only a simple sketched general layout and with much reduced and very basic gaff sail plan detail is here.
The beginnings of an exceptionally fine build in the USA can be seen here.
LOD: 4936 mm or 16ft 23/8"; LOA: 6036 mm or 19ft 95/8"; BOA: 1820mm or 5ft 113/4"; maximum designed displacement: 575 kg, minimum 330kg; hull weight: 135 - 160 kg; ballast: 75 - 125 kg; sail area - gaff rig (nominal): 123 sq ft - 11.4 sq m. or 136 sq ft - 12.65 sq m; lug and yawl approximately 11.5
There is no guess work or trial and error in the lining out of the planks for the clinker version as the position of the plank edges is clearly defined on the plans.
'Pearl' with standard bermudian sail plan. Off-the-shelf or season-old ex-racing 'wayfarer' sails may be used if wished for inexpensive fitting out, as an alternative, to give the widest possible choice of nearly-new or used equipment. Far better to trim costs on items that can easily and simply be replaced at a later date than compromise on plywood or timber, if needs must. Sail area: 165 sq ft or 15.34sq m.
Lines, offsets and strake panel offsets only [though with 3 sail plans] are available for Annie, a larger version of Pearl.
A rather lovely photo of a completed Annie, though strip planked and without the defining lines of the strakes, and with Pearl's rig, not Annie's, can be found below on the BBA's Facebook page and on the blog of a Herreschoff inspired build. Conversion to round bilge was accomplished by rounding off the hull using the given and highly accurate offsets, confirmed in a full lofting, and has clearly worked extremely well, producing a very pretty hull, though the transom, whilst still pleasing, is less successful to my eye than than as originally drawn, as it has become a little heavy and over-emphasised by the filling in and rounding off compared to the chiselled look of the original: the clear lines of the planks at the turn of the bilge and tumblehome in the transom producing a lightness and definition of line that has inevitably been lost in the rounding off process - as can be seen with the direct comparison with both Pearl and Apple. Others clearly disagree! Still, each to his own - you pays your money and makes your choice - and though I made it clear that rounding off the knuckles would not be my choice with this design, as I've said before, it is the boatbuilder's boat, his efforts and skill to create what he sees in his own mind and not simply a clone of what others have done, though there are too many precious, self-satisfied designers who would deign to recognise this - and who would be incapable of building to their own work at all, even had they half the skill to try. So meet Annie, as interpreted and realised by the builder and owner, Ian Davidson, and the Boat Building Academy of Lyme, England. Here [BBA Annie] and another here: [BBA Annie under power] and here [BBA Annie]

Two versions of a 19ft Apple/Pearl cross for fast, spirited day-sailing with a gaff cutter rig are also available as lines and offsets.
