Naked mast myth - Buff performance with no lee side!

Cruisers are beginning to see and ask about my new rig for my 65ft trimaran.

I have prepared 3 presentations. These links take you to PDF files on boatdesign.net.

The presentations explain:

1. What led me to not put another Bermuda rig on my trimaran.
2. Alternatives I considered and why the mast is now in the back.
3. A very unique kind of rigging that spreads load to 4 chainplates.

Before you read them, remember my goals were in order:
Safety
Windward capability
Price
and racing was last.

If you follow the presentations you will see I elected to ditch the mainsail and only go with a big traditional lifting foresail.

My mast has no sail behind it. Some term this kind of mast as being a "naked mast". Further, some claim this hinders performance greatly.

I disagree, and have provided evidence in my presentations.

My presentations may interest you if the topics of mast compression, demasting, and weather/lee slack on standing rigging worry you.

Just recently my hand-tight style of rigging supported my 62 foot mast and it stood against super-typhoon Yolanda (Haiyan). She tore down the trees in front and behind my sailboat, but the mast stood fine. The eye of this typhoon made landfall within 30 miles of my sailboat.

Re: Naked mast myth - Buff performance with no lee side!

This trimaran was built in California and designed by Jay Kantola. She was launched in 2000 after 8 years of construction by the owner who was a professional boat builder.

Chris White describes this style as "third generation" with computer modeled hulls. Attached is detail photo of the hull.

About a year back there was a Hughes trimaran from California that sailed into Malaysia. That owner reported the same issue that the former owners of my boat did. He was told to put on a big Bermuda rig and it would be easy to simply reef it if necessary. Both he, and the former owners of my boat, found their big Bermuda rigs too scary for a cruising boat.
