Norman Cross Trimaran

Hi, hoping this thread isn't dead. We live on our Norman Cross 34 in Cairns, Far Nth Qld, Australia. Looking for plans and also get in contact with other owners of Norman Cross 34 trimarans to compare notes. My email is GeoffHolland007@gmail.com. Did anyone find out what happened to Jeff Turner?

 

I haven't heard what became of Jeff or the plans. The Mariners Museum in Newport News Virginia USA has some Cross plans in their collection and a excellent team in archives and photagraphy.

 

I contacted the Mariner's Museum, they really do not have much in the way of plans. They have some plan drawings but not enough detail to build from, I don't think.

 

Hello Ron, it sounds like you might have been part of the 50' that was built down there at South bay Multihulls which I now own. It would be cool if you had pictures. That is you are still on this site?

 

I have a Cross 38 and I need to do some deck repair. I live out of the USA so getting British measures in plywood difficult.


I need to know the deck size of plywood, I think it is 3/8 inch, but I would like to know before I purchase and ship to my location.


Can you tell me the thickness of the deck plywood?

Why don't you drill a hole in the deck and measure?
Cross information seems to be really scarce.

 

I am looking for plans to build a cross 38 here in the philippines. I have a 46 foot mast and boom and standing rigging from a wrecked hedley nicol boat and this seems to match. Or hedley nicol plans. Any ideas? Here is pic of boat that was wrecked.

 

Briter. The following is plywood, is a trimaran, several are sailing and have crossed oceans. The Farrier Command 10 which is about 35 foot long. Full free plans are available at: MediaFire https://www.mediafire.com/folder/56wr7egnhypqc/Command_10

 

Ahhh, looks like you had a Nicol Buccaneer possibly which were the last design Hedley was working on. Since he died before they were finished no 2 are alike. The guy who became Bruce Roberts of plan and kit fame skipped off with Nicol plans and peddled them early on.

You need a bigger boat than a Vagabond MK2 for that mast, stock height is 38 and plenty of power, anything over 40 is a bad idea.

Still hard to find Cross plans, especially as the Mariners Museum closed. Mystic Seaport might have some.

For the Philippines building I think I would suggest a Marples Seaclipper of appropriate size to take that mast. John has plans that are affordable and the ply build will be fastest to construct with local labor.

 

Cavalier, the museum in Norfolk VA closed?

 

My mistake on the Mariners Museum in Newport News Virginia, I heard it closed for awhile but the website says it is open. The Cross plans are part of the D.H. Clarke Collection. Not sure what is there. They also have Newick and Piver collections.

 

Great. I'm not too far away and I get my resin and cloth in Norfolk. It's on my list to stop in there I just never seem to have the extra time.

 

Thanks for the response. I have an experienced builder here who has built several multihulls for andy smith here in bohol. So pretty confident in his abilities. The museum does have cross 37 plans and am waiting to receive those plans. I may modify and stretch. The aluminum mast i have is 45' and rigging would need some modifications . Also the hedley was a cutter rig. So im wondering if i can accomodate existing rigging to the cross 37 design. Any thoughts?

 

As I recollect the Cross 37 is one of the older chine hull designs for sheet ply. I think it was set up as a ketch but could be converted to a cutter as could most Cross ketches with the correct mast step support and reinforcements for the moved chain plates. Cross Tris are easier to work with mast location than some boats because the keel can take the load of the mast step support beam that tends to land between bulkheads on a cutter.
Also if you stretch move all the stations a bit, not just the bow and stern. Trevor Banks 45 actually was built around Cross 39R molds so it can be done but again, know your engineering.

You also might try to contact Dsanduril on the multihull section of Cruisers Forum who has plans in rough condition for the Cross 40 which was a stretched 38 with the curved cold molded hulls.
That boat went around the world several times. Check your sail area and mast height when sizing up a boat, if it is too different look at something else.
I still like the Sea Clipper idea for current designer support if you aren't used to playing with this stuff.
