Focused on performance cruisers in the range of seventy to ninety feet (21..26 meters), ranging from seven to eighteen tons displacement. The interiors differ in scale between 70 and 90 feet (a mere ten feet in half the boat...); a little more roomy but not enough to offer significantly different floor plans. Proas this size are suprisingly small when it comes to accommodation; it's actually very difficult to squeeze a Venezia 42 into a 70' proa! Design features in common: structural core, hulls, crossbeams, bridge deck, steering and rig. They differ in arrangements of the cockpit and pilot house with consequent effects on interior layout options: full salon pilot house, walk-around pilot house, bridge house racer and day charter versions have been identified. |

At 35 degrees roll, the pod carries 4,400 lbs. displacement, 7+ feet to leeward.
At 45 degrees roll, the pod suddenly carries more than 50% of total displacement, 7+ feet to leeward.

April, 2008 - Twenty years ago(!) this summer, the idea took hold of owning a full time live aboard 70' Pacific proa. But it was always clear to me that the cost would be at least as much as having a custom 43' catamaran professionally built (~US$300K). And of the few who can afford that, very few of them want to gamble that small fortune on something as novel as a large cruising proa. So my thinking now is that 90' proas (and up) might have a better chance, as crewed commercial charter boats or private yachts, where money is less of an issue; equivalent to a 49 passenger, 55' catamaran. |
