Well the short answer is that it would be debatable as to whether you could call it a handplane. In practical terms though it was a question I thought could be best answered by doubling the size of my handplane.
Taking the template of my latest handplane design and doubling the proportions in length, width and thickness I came up with this design. Constructed using the Roy Stewart method I utilised in my Coffee Table Sim I learnt from the mistake of last time by filling the hollow chambers with XPS foam, thereby keeping it light but also protecting against the leak issue that did for the coffee table.
Completed this board a few months ago but only recently got around to test driving it and have to say I was more than a little impressed. As opposed to the handplane which allows you lift your upper body out of the water on waves, this little rocket has actual drive, helping you into waves as well as pulling you along when you catch one. Even without flippers I've been able to catch waves, find a line and get pulled all the way into the beach. Seriously blown away and already started work on the sequel, reckon I could always find a spot in the van to keep this little sucker handy.
