A primary goal of the present invention is to improve the prior art assembly system. The present invention provides a boat of simple ultra light construction with the fewest number of parts that can be easily assembled without tools. Then, when disassembled provides a compact lightweight package suitable for long range or rough terrain portage or back packing. A plastic coated nylon waterproof cover or like skin can be conveniently slid onto, and off of the assembled hull and quickly fastened in place to provide waterproofness for the hull. Another goal of this invention is to introduce a watercraft construction method whose components can be made from extruded corrugated plastic and other plastic materials that are lightweight, but strong, and can be inexpensively mass produced using rule dies and the like inexpensive tooling and assembly methods.

The seed planter of claim 6, wherein: the valve is a sliding block, and the first and second holes extend through the block. 8. The seed planter of claim 6, wherein: the valve is moved by a solenoid. 9. The seed planter of claim 6, wherein: the valve moves linearly. 10. The seed planter of claim 6, further comprising: a selectively-deployable alley wiper mounted adjacent the seed plate, the alley wiper dislodging all seeds in the row when deployed. 11. A method of planting seeds, the method comprising: (a) picking up seeds and positioning the seeds in a single-file, circular row with a seed plate by rotating the seed plate through a seed chamber containing seeds; (b) dislodging excess seeds from the row; (c) collecting the excess seeds in an excess-seed compartment; (d) evacuating the excess-seed compartment using a vacuum source; and (e) releasing the seeds from the row on the seed plate, the seeds falling one-by-one to the earth. 12. The method of claim 11, further comprising: (e) moving a valve to redirect the vacuum from the excess-seed compartment to the seed chamber for evacuating the seeds in the seed chamber. 13. The method of claim 11, further comprising: (e) removing all seeds from the row on the seed plate by deploying an alley wiper to dislodge the seeds. 14. A seed planter, comprising: a seed chamber having an inlet passage for receiving seeds to be planted; a rotating seed plate that cooperates with the seed chamber to pick up and transport individual seeds from the seed chamber to a release point, where the seeds fall to the a singulator that monitors seeds picked up by the seed plate and rejects excess seeds, dislodging the excess seeds from the seed plate; and an excess-seed compartment located adjacent the seed chamber and under the singulator for collecting the excess seeds rejected by the singulator, the singulator being oriented relative to the seed chamber such that all excess seeds dislodged by the singulator fall into the excess seed compartment, bypassing the seed chamber. 15. The seed planter of claim 14, further comprising: a selectively-deployable alley wiper mounted adjacent the seed plate, the alley wiper being pivotal from a storage position to a deployed position while the singulator remains stationary for dislodging all seeds from the seed plate for collection in the excess-seed compartment. 16. A seed planter, comprising: a seed chamber having an upward-extending inlet tube for receiving seeds to be planted; a rotatable seed plate having a circular row of apertures that rotates through the seed chamber, the apertures communicating with a vacuum source to pick up and transport seeds from the seed chamber to a release point for dropping one-by-one onto the earth; a singulator mounted adjacent the row on the seed plate that dislodges excess seeds from the row on the seed plate; an excess-seed compartment mounted below the singulator and having an upper opening for collecting the excess seeds dislodged by the singulator; a vacuum tube extending through the upper opening into the chamber for evacuating the excess seeds from the excess-seed chamber; a stationary valve plate mounted above the seed chamber and the excess seed compartment, the plate having a first port into which the inlet tube of the seed chamber extends, the plate having a second port into which the vacuum tube fr
