Lapstrake Sailboat

Rowing Version if you're a glutton for punishment.

Outboard Motor Version if you just want to enjoy the simple things.

This started out as a proof of concept to see if I could make a lapstrake or clinker-hulled boat in SP using hollow fuselage blocks and the slicing tool. It ended up as a kinda functional sailboat! Some knowledge of sailing will be useful in controlling the boat, but water physics is pretty rudimentary in SimplePlanes so it's not great.

Controls:
Use Yaw to steer with the tiller, and Trim to set the rudder angle to counteract weather helm (both Yaw and Trim move the rudder, but with Trim it stays where you set it).
Use VTOL to sheet in and out (adjust the angle of the sails). VTOL up to ease (let out), VTOL down to haul (pull in).
Raise the Landing Gear to raise the centerboard for beach landings or (carefully) when sailing directly downwind. Stability will be compromised with the centerboard raised, and the boat will make more leeway.

Literature:
This simple lapstrake skiff from Lookfar Boatworks is ideal for use as a family daysailer or on shorter overnight expeditions. She comfortably accommodates four people (or two with overnight gear), and is a fun and forgiving vessel in winds up to 25 knots.

This version is planked in Western Red Cedar on steambent White Oak frames. The backbone and floors are Purple Heart, and the transom, centerboard trunk, and trim are Sapele. Thwarts and sole boards are Red Cedar, and the spars are Sitka Spruce. The skiff is rigged as a fractional sloop with a self-tending jib and a weighted centerboard.
