This is a 3d printed version of a scratch built radio controlled schooner. A video of this model sailing in strong winds is shown here:https://www.youtube.com/watch?v=wwWV6K05fUc&t=10sA radio controlled model schooner always attracts an admiring crowd (especially women) as they are a majestic sight sailing into the wind. Experience has shown that a model schooner with a full set of sails would not perform well unless there is a deeper than scale keel attached. Therefore, a slot that runs along the keel in the hull is designed in for a detachable fin with a weighed bulb for added stability.
The 1923 hull lines and deck arrangement of the schooner Columbia were used at 1/32 scale for the 3D printed version. The hull is divided into 9 sections for printing on a 250 x250 x 250 mm bed. Longer hull sections are provided for printers with larger 300 x 300x 300 mm volumes. The hull has planking lines, bulwarks and scupper holes drawn in.
The auxlliary motor uses a RS-380 DC motor with a GT2 timing belt for a gear reduction of 1:3.The fore and main masts are removable for ease of transportation and storage. Two Hitec HS-785HB drum type sail winches are used for sheeting the sails.

Sails can be fabricated using pre shrunk cotton cloth, lightweight Dacron or Tyvek sheets.A hollow 3D printed bulb that can be filled with lead shot is provided. This bulb is attached to an aluminum fin which slides into the hull’s center axially from the bottom and secured with a cotter pin at deck level.Hull access is provided via removable locker, main cabin, anchor winch, rudder housing and various hatches.Wood PLA is highly recommended for the hull and deck. Cura’s ironing feature on the deck surface creates a basswood like texture.Fully rigged dimensions with detachable keel inserted are:1607.0 x 244.5 x 1380.5 mm
