Boat Projection

Molkit does not currently include a dedicated boat projection template. The projection tool flyout (shortcut J) offers Fischer, Newman, Haworth, and chair entries only, and the renderer has no boat-specific layout. Flagpole and bowsprit positions are not modeled; the chair projection models axial and equatorial positions only. This page covers what you can do today.

Current support

The chair is the only six-membered ring conformation with a built-in projection: hidden ring carbons, paired axial and equatorial substituents, a Flip Chair action, and a chair section in the Projection Properties panel. All of that is documented on the Chair Projection page and none of it changes for boats, because there is no boat counterpart to switch to.

A boat you sketch by hand is plain bonds, not a projection annotation, so selecting it does not open the Projection Properties panel and there is no relayout or flip action for it.

Start from a chair

If your figure contrasts chair and boat forms of the same ring, place a chair first. You get editable substituent labels and the ring sliders with no extra work, and the chair sets the scale and line weight your hand-drawn boat should match. See Chair Projection for placement, substituent editing, and panel options.

Sketch a boat by hand

Use the bond tool to draw the ring skeleton directly:

  1. Draw the four bonds of the flat middle section, then angle the prow and stern carbons upward at each end.
  2. Switch the bond flyout to the Bold bond type for the front edges if you want the same depth cue the chair renderer uses for its front bonds.
  3. Add substituents as ordinary bonds drawn outward from the ring corners, then double-click a terminal atom to rename its label (for example OH or CH3).

Place flagpole substituents pointing up from the prow and stern by eye; Molkit does not snap or label these positions.
