could a grainger 075 trimaran be a grandfathered into the 8.5rule?

LOA is 7.05mtr but floats are 9mtr...

if so anyone any ideas what it would cost to get sirocco from brissy to ak?

in a 40' container i guess

A 20 ft container door to door Brisbane to Auckland can be under $5,000 or it can be up to $7,000 depending on the packing services needed. A 40 ft container can be up to twice this. You really need to get a custom quote from one of our sales consultants.

Antipodean designers also featured, with catamaran designs by Malcolm Tennant (Spyder) and Ron Given (Turbo Tiger). The original Grainger 075 was also designed with this rule in mind.

This brings up an important point – NZ 8.5 multi’s don’t have to be 8.5 metres long. Provided a boat is within the box dimensions and meets the other requirements it can be measured under the rule (eg. Buccaneer 24 Capricorn). There is a grandfather clause allowing boats built before the advent of the rule some leeway in terms of headroom etc (eg. Hughes 24 Creepy Crawler, TC 790 Hard Drive) however new builds of older designs would likely require modification to suit the rule. If in doubt contact the 8.5 measurer for advice.

hmmm...looks like the mast is too tall at 12mtr, but if that were taken care of would the floats also need a to be, gulp, chopped?

An 075 built to plan ( I have a set) measures 8m loa x 6.1 beam with an air draft of 12 metres or so with a 10.7 metre stick, so wouldn't need any exemption to race as it is within the box and has the required headroom etc. The example in the ad does appear to have the float bows lengthened, but it doesn't look like 2 metres from the pic. The measurements given may be a typo so should probably be confirmed. If it is the right size it looks a good buy at that price provided the shipping isn't too steep. If it is 23' long then its probably an 071 with a cabin, although the interior looks too big for that.


I suspect (remembering the Penelope argument a few years back) an over height mast or over length anything would likely have to be altered.

If you want 7.5m racing tri's check Creepycrawler
probably a half to 2/3rds of that price once it's landed and Creepy is probably faster.

You're not comparing apples with apples. Creepy is essentially a day sailer with a shelter cabin (plans are available for a completely open version). Great for racing but not the sort of boat you'll take the family away for a weekend on. The Grainger 075 is the equivalent of an F82 in terms of room and performance potential, demountable though, not a folder. Small Grainger tris seem to do pretty well racing in Oz.
