When are the new boat designs coming?

Submitted by Matthew on

My handful of regular human readers, and my truckload of regular spambot readers, might be wondering why I haven't listed any new boat designs since the Almaguin 400 and 500.

The answer is that I'm currently in the (hopefully) final stages of a graduate degree in medical physics. That means a lot of time in the lab, and a lot of late nights and weekends spent poring over calculations, making figures, and writing up a thesis.

Boarding ladders for small boats

Getting into a boat from the water is HARD. The drag of the water makes it difficult to jump, and there's often no bottom to stand on. Even if you're in good physical condition, it's quite difficult to heave yourself more than about 15 to 30 cm (6" to 12") vertically out of the water. Take a look at a swimming pool: the copings are rarely more than 15 cm above the surface; in the best modern pools, they're level with it. Most people just can't jump any higher out of the water.

Let's look at Sunset Chaser for a moment:

Length-beam ratio

Definition

L/B = length divided by beam.

Units: Dimensionless.

Usually, the waterline dimensions LWL and BWL are used for monohulls, or for a single hull of a multihull.

What it's used for

Performance

Larger L/B indicates a slimmer hull. This usually implies less wave-making resistance, and thus more efficient high-speed performance, but also suggests reduced load-carrying ability for a given length.
