      To go without motor; or not? Not meant as brick throwing, but...
      really... I ask you, BRICK... rowing? It's pull on the oars and
      there's a surge forward, then a stop. Surge, stop. Surge, stop. No
      glide. Things could get worse. Oars may be dependable, adaptable,
      and have so many other virtues that it would take a book to analyse
      them properly. It has. Several. However, stop for a moment to think
      of the antagonistic feelings induced in an onlooker who has the
      visage of this seeming untrusting skuller retreating before them,
      eyes never directed elsewhere other than back in their direction,
      back never turned on them, as the lurching suspect getaway is made.
      Shuffling, rearward. Stop. Surge, Stop. Surge...

      Steady skulling with a good yuloh, perhaps short and folding like on
      SWALLOW #392, should give smoother progress. There might be a lot of
      energy saved too. Anyone tried it in BRICK? How did the surrounding
      people react? Did any shout out? Throw things? Dial the authorities?

      At stern, or bow (which is which? when or where?) a paddlewheel
      crank turned by offset pushrods, driven by either footpedaled
      levers, or a lever or levers pumped by hand, or both, could be a
      motive solution. Think: cross-country-skiing gym machine. The
      pushrods are connected to the actuating levers at a height above the
      gunnels, so that the pushrods don't interfere with the gunnels or
      transom. A moderate sustained effort results in a smooth continuous
      push at whatever comfortable speed. Round and round the paddlewheel
      goes. No surging, no wasted effort in oar slippage after repeated
      dead stops. A much more dignified BRICK progress, even graceful.
      Twin reciprocating jellyfish oars slung over the transom may have
      similar possibilities for power pulse smoothing too. However, some
      onlookers, "goongoozellers" I think these ones are called, THAT'S
      GOONGOOZELLERS, may doubt the skullers motives. Goongoozellers may
      take the skuller's arms - moved in that manner - as a suggestive
      obscenity directed at them, over and over, and the hapless
      jellyfisho'wheel skuller may find themselves in hot water.

      Wendel Vondersaar's 1892 US patented rowlock* for long, long, double
      paddle might not be quite as smooth, as yuloh, wheel, or jellyfish,
      but better in that regard than oars. This single cunning rowlock is
      mounted amidships, on an adjustable post, at convenient height and
      distance, and before a comfortably seated paddler. The oarlock bears
      the paddle weight, not the paddler. The paddler faces the direction
      of travel and wields the paddle in a kayaker like manner. In
      addition to saving the effort of holding the paddle aloft the
      oarlock provides a fulcrum for the paddler to work against, thereby
      increasing mechanical advantage over that of the conventional.
      Another efficacious advantage bestowed by Mr Vondersaar's
      contraption over oars in propelling BRICK, as I envision it, is that
      the lag between power pulses is hardly there at all. The
      comparatively smoothed out power pulses result from approximately
      half the power of oars being applied at twice the rate. This might
      provide onlookers with a maritime spectacle of more refined and
      elegant steady progress, and may be more satisfactory for the crew
      who has an easier go of it. The oarlock device itself may be
      conveniently stowed when not used for propulsion, or functioning as
      a drinks stand. However, the long, long paddle is at a disadvantage
      compared to oars when stowing due to that necessary length. This
      disadvantage may not be the case where delicious fruit are to be
      found aloft in mango or coconut trees overhanging the water along
      the shoreline. Just ripe for a lengthy lunch, if able to be reached.
      Nor will the length be at a disadvantage in submerging the lunchtime
      beverages in deeper cooler water layers, for more rapid chilling
      prior to serving. Not that it's likely to be a hard earned thirst
      that needs asuaging, but a skuller of a boat that so resembles an
      Esky is surely to believe that any thirst at all is deserving of a
      good cold drink. The body language of such a skuller under way may
      seem delightfully inoffensive, antagonising no onlookers. Pleasant.
      The body language of this skuller may indeed seem agreeably
      sociable; as that of one, who, from a feeling of utter contentment,
      waves in friendly manner to all about. Nevertheless, goongoozellers
      may give chase - for the mangoes and drinks.

      It is possible to skull with a boomed sail. That's done
      by "pumping". It's against the rules in all racing classes except
      the Olympic sailboard. Size of roach in the leach does matter, and
      is measured. Olympic sailboarders may expend more energy and sweat
      in an event than other endurance atheletes do. They say they enjoy
      it, and at regattas will do it several times a day. I don't want the
      onlooker trouble that pumping in BRICK could bring on, so would
      consider a sail that is sized for light air to be a better option.

      BRICK may be an excellent boat in which to master the mysteries of
      the dipping lug. Seriously. BRICK is stable, very wide in the
      quarters, full in the bow. BRICK is capacious for its size, yet
      everything is easily within reach. Maybe, not being merely double
      ended but also bi-directional, it would do to learn the art of the
      proa? Perhaps that wheely depends on whether there's oars or
      paddles?

      Anyway, I thought I might lift the sail from LITTLE SUPERIOR #288
      and fly it in BRICK #458.

      On another smaller sail, less suited to a BRICK in light air, the
      club boom would still be very desirable for resolving the issues of
      sheeting angle, foot size, and boat length.

      My dipping lug club problem is this: how is the club managed when
      reefing? It seems that the reef clews are tied in to the club as for
      any boom, but won't the club then hang down forward under the weight
      of gravity, and won't that be added to by the force of the sheet
      tugging down on the club? Are the reef pendants meant to take the
      strain? Do they have to be uncommonly reinforced, or perhaps the
      whole sail has to be extra heavy duty if the pendants are meant to
      support the club rather than merely securing the reefed sail bundle?

      Cheers
      Graeme
