Atomite MkII Twin Cockpit – 9ft Hydroplane


Atomite MkII Two Seater is available to purchase as a full size CNC cutting plan set or a CNC cut kit of parts. UK mainland shipping is included in the kit price.

SKU: AMKII-2 Category:


Atomite MkII is a 9ft hydroplane and is much the same as the original design of Atomite by William Jackson. This version has been slightly adapted for more practical use. A small forward cockpit was added with an incorporated, CNC slot together seat design. The forward cockpit is great for taking the kids out and will happily accommodate two little ones. The aft cockpit has been narrowed and strengthened to allow the driver to sit up on the side deck.  I have made several corrections to the measurements of frame heights, but other than that the hull and layout is as per the original. There are several parts that I have improved upon from the original plans, particularly with respect to modern manufacturing methods. A nice simple little build that should be a good bit of fun.

This boat is available to purchase as a digital plan or a pre cut boat building kit. Details of each are listed below.

Boat Building Plan Set

The plan set is for a plywood skinned version of Atomite MkII. It contains an illustrated document showing assembly of the parts and a SketchUp Model for referencing the general assembly and location of all components.
