    Marvelous photograph of the Walter Greene trimaran ex-Friends and Lovers, now Bilfot, preparing for Route du Rhum. This boat was originally sailed by Kiwi Phil Steggal.

    Here's a not-so-marvellous photo of her waiting for the start in St Malo.

    Beowulf Vl seemed ahead of her time.

    Certainly a simple effective concept and famous to boot.
    While I see the benefit of having the front bridle meet higher up in the air, is there any special reason why the clew of the jib is so high?I suppose it tended to avoid having to change the jib sheet position fore and aft in a wide range of wind, maybe?

    I wonder how much it could be improved with current techniques? carbon mast, carbon huls, carbon beams like everyone else - what else?

    Oh yeah - Doug's hydrofoils.

    I don't know about the headsail, I suspect that is an off the wind configuration and that she went to weather bareheaded. Maybe Gary or some one knows for sure. I think this is circa 74/75.

    Moggy, Thanks for the link and the reminder...I was then a keelboat guy but even so, two cats had my total interest...Beowolf and the Sharks...and M Scows. One of the great boats, no doubt, Beowolf in all its configs. Foils would have ruined the whole deal, as Mr. Upchurch intimates. :)]

    Notice those new fangled, to windward, una rigs on Beowulfs IV, V and V! ... 40 plus years ago. Gasp!
    Still hasn't really sunk in - bar a couple of "new" designs.

    Gary Baigent +1. And half hulls of "foam." Amateurs rule.

    I wonder where in the Bay area that boat sits...anyone know? Or, did forty-plus years do it in?

    Probably because it has a high bridle. a lower one would increase the inward pulling loads on the bows, which are not held apart by a netting beam. And the high clew is so it can sheet to the aft beam

    Made my day. Don't know squat about stresses, but had the idea that the low one would pull the hulls in too much...maybe I missed my calling, so to speak. I do drink beer, but should have hung out over the rail more?

    Thanks Richard Woods.

    Here is the latest A Class (beauty) from Hall Spars and Rigging; the A has been around since the early 1960s, still the same platform measurements - but the aspect ratio of the una rig has changed a little as has the bow design ... as have the foils.

    In the actual trend...As always in "fun" leisure boats design over function. Never paint a small boat in black. Never let a black boat in the sun...Specially in composite, a part the burns, you have the risk of resin softening and to have deformations and delaminations. At midday under a tropical sun you can cook eggs on the deck and to get hot water for the tea. I hope there are pressure relief valves on the hulls, like on the old boilers, I imagine hot in the sun-cooled in the water, a hundred cycles and lets have a look on the hulls.
