"We had an absolute blast riding it but it was very hard to ride. It paddles in a straight line better than any surfboard I've paddled. It's no wonder Tom won races on this thing. Turning is another story. Tilt your feet right and it goes left!"

What's so displacing about these so called displacement hull boards. :? Any board/hull will displace water to some degree. In shipping water displacement is used to determine minimum ballast and maximum loading of a vessle but untill recently that's the only time I've heard of it. Even that Riddel bloke says he now calls them sompthing else. Is there anyone that can displace my doubts on this issue.

Hi Astro.

You are correct. All hulls displace water, even planing hulls.

The displacement tail design is so called because it makes a gradual transition from a predominantly planing hull type to a 'displacement hull' shape. This means that the proportion of displacement based lift to planing based lift increases towards the tail. This is excellent for control and it ensures that control remains consistent over a wide range of speeds.

I have written many times on the fact that the term 'displacement hull' is a misnomer when applied to the kind of boards made by Liddle and co as they are predominantly planing hulls. The extreme pintails which we use are however predominantly of true displacement hull shape. The boards are thus hybrids. I never refer to my pintailed boards as displacement hulls, it's a term which only applies to the tails.
