It is projected that the announcement will be made in November 2012 of the multihull selection.

Here are the basic requirements for a Multihull coming along to the trials, taken from www.multihull2016.com:

(a) Boat Characteristics:

1. 2-person multihull type
2. Sloop rig with an Asymmetrical Spinnaker
3. FRP construction of hulls
4. Two part mast
5. Twin trapeze
6. Unsinkable when holed or swamped with approximately level floatation. The boat, when swamped, shall float with some portion of the freeboard, or deck above water
7. Easily righted by the crew without external help
8. Able to be shipped in a 6.1m (20ft) container
9. Trailerable maximum width 2.59m (8ft 6in)

(b) Performance – per the following approximate descriptions:

Racing is expected to be held in winds in the range 5 to 25 knots
Higher winds should reward the skill and experience of the sailor
Above 25 knots the crew may be in survival mode, but the boat is robust enough to continue without breakage.

(c) Construction Manuals/Design Calculations and Support

All offerors must present preliminary documents for initial review to be invited to attend sailing trials. (See 1.b)
All materials will be considered proprietary to the offeror.
Every item that is used while racing should be included in the submittal. For example the hull, mast and rigging, appendages and sails.
Level of completeness will influence the evaluation.
As a minimum the following drawings are expected to be submitted for review; Hull Construction Laminations Plan with Bill of Materials; Appendage Construction with Bill of Materials; Plan view of Control Lines; General Arrangement; Sail Plan with Bill of Materials; Rigging Plan with Bill of Materials.

(d) Safety – Isolation of Mast from Power Lines – The proposed equipment is to provide a measure of safety from inadvertent strikes of the mast to the overhead power lines.

(e) Transportability of Equipment – Should be capable of transport by containerized shipping. For lowest cost, options to ship in a standard 20ft unit should be considered and presented, as well as the 40ft unit option.
