Marty,

A few years back, well before the pandemic, I attended a talk that Tad Roberts gave at the Port Townsend Wooden Boat Festival about what constitutes good design. Although he was talking about boats, he actually started with the ideas of ancient Roman architect, Vitruvius, which were that good design should combine three things, which he labeled Commodity (utilitas - efficient arrangement of spaces & systems to meet the functional needs of its occupants), Firmness (firmitas - physical strength secured the building's structural integrity), and Delight (venustas - style, proportion, and visual beauty). Tad observed that these ancient rules could also be applied to boats, i.e. good design is timeless.

Tad proposed his own three rules for the aesthetic aspect of boats, which he says should be Balanced, Formal and Austere. He proposes that, in addition, there are other attributes which result from good design; Excitement, Cohesion, Elegance, Identity and Practicality.

I was struck by this approach and it occurred to me that these ideas could all be related to each other in a 3-circle Venn diagram, with Commodity, Firmness and Delight comprising the three circles, and Tad’s additional rules falling in various places among the circles and their intersections. At the very centre, in my view, at the intersection of all three, would be Balance, Identity and Elegance. As Tad continually points out, boat design is a matter of tradeoffs of all these elements and how to balance them.

If you take this Venn diagram approach, you then have a useful tool for looking at the various trends in boat design, including specific parts of the boat like bows, or how well the overall bits of the boat hang together.

To take your example of plumb bows, by themselves, I would have to ask how well they fit with the rest of the boat and how practical are they for the boat’s intended purpose. They might be fine for flat, protected waters or a flat-out racing boat like an IMOCA 60 where you can put up with the discomfort, but in an ocean-crossing cruising sailboat do they provide sufficient reserve buoyancy to prevent serious pitching when thrashing to windward 1,000 miles offshore in a big head sea?

For an example of overall boat design, such as the Axopar boats, I would argue that while they might be practical and structurally strong enough, they fail on identity, elegance and balance. They look to me like a wannabe Bond villain boat, but clearly aren’t. The various parts do not make a harmonious whole and I don’t think anyone would call them elegant.

Try using this mental checklist the next time you walk the docks.

Boat design these days is probably like a lot of things in the world now, a performance only with no evidence of reason and often displaying something more akin to insanity.
