I dunno, Lagoon gets away with it??

i saw this cat last nite at Mill Pond in Bedford Basin NS. Please excuse the ignorant question: is this a Wharram? She's about 15 meters long.



i thot it was interesting how the staysail stay is attached:

Definitely not a Wharram. Looks like a TRT.

My guess is that it is one of the highly modified Woods Mira catamarans It has the right bows and stern, and appears about the right size. It was a very early Richard Woods design from shortly after he parted company with James. The deep V hulls and bow shape suggests to me that this is what it is, also the rudder setup........... Google it, and you will see quite a few photos, and several highly modified boats. Originally it was an open deck boat with inboard wings. These are reputed to be a superb "blue water" boat.
I really like the pilothouse.............



Note the hull shape and rudder design in this photo of a modified Mira.

Wow! The Woods Mira looks like a great boat. I want one.

Yes, I think you are correct.

It’s a Kohler 42

I sure missed that one ;-) I thought I knew Bernd's designs fairly well but the Manta at 42 feet is above my "interest range". I love his philosophy of simplicity and ease of construction, and as an engineer myself, the way he integrates things for structural strength, rather than designing structures that have but a single function. He's a brilliant designer. His anti votex panels have proven an abysmal failure for reduction of leeway.... IMHO... "supported" by no less a personage than Pete Hill who found one missing and no difference......... You will note that the KD 860 design now includes a single centerboard............ The Manta of course is a different story with it's deep V Wharram style hulls... This does not reflect negatively on the designer at all IMHO. He is honest and flexible enough to move on........... I admire that!

I wonder how many have been built.........42' is HUGE for home builders.

Having read some of the travel blog of Pete Hill and wife Carlie, IIRC, Pete had LAR keels on his stretched KD 860 and lost one of the keels and said they had not noticed until hauled out in S. Africa. there is a series of photos showing him fabricating a new keel.

Some years ago, I met a south African couple in FL who sailed a modified Woods Mira design (original builder had added bridge deck cabin) having twin swing centerboards and cutter rigged. They said the boards were rarely used. Lost THE engine approaching Trinidad and entered port in Chaguramas (sp?) not using boards or engine.

Jim:
It was not an LAR keel that fell off, but an anti vortex panel, and Pete then installed the LAR keels...... You will see that if you reread. The AV panel is a small triangular protrusion that extends laterally inboard from the corner of each hull.



If I did this right, there should be 3 photos here. One of Bernd Kohler's AV panels, and two of Oryx on the beach in Portugal early in it's life, before pete added the keels..... obviously from the photos there are no keels at this point. He added the LAR keels, and later lengthened them (Uruguay I think). Bernd later offered two board options, only one of which is shown on the KD 860 site, which is a single centerboard in a pod between the hulls, The other was what he called "luff boards", and the drawings are available as far as I know......... It consisted of two leeboards, each on the inboard side of one hull rather than being on the outboard side as leeboards usually are. These are fairly slender airfoil shaped boards...NACA 230 series I believe, and retract by swinging aft like a centerboard. Oryx was lengthened considerably, from the plans (1.4M I believe), and you will see in the photos it has a chine at bridge deck level to give more interior space, which the KD 860 design on which it was based lacks. You can find and download a PDF from Kohler's web site describing the AV panels and how they work. I've also included a drawing of the centerboard from the Kohler web site.

There's a nice looking one in one of the french sites listing boats.
