Dave or anyone else,
Give me a call at 07 3879 8550
The boat is at Beveridge road in Thornlands at the southern end of Brisbane.

I would envisige a total loaded weight of no more than 3.5 tons.
This boat is not designed to carry a payload of 3400 kg payload.
regards,
Beau Lyons
or send me an email at beau_lyons@yahoo.com

I thought I would show a couple of other variations I have developed using the Triflector principle of hull design.
The catamaran configuration was my first consideration.

Triflection is well suited to a Catamaran configuration. The main advantage being the very broad stern which gives better fore and aft stability and much more useable room below and a much higher load carrying ability.
Low friction sharp entry,No bow wave is developed and there IS NO INTERACTION between the waves from each hull.
This particular sketch has not been refined but is shows the principle involved.

The reason I did not go with this configuration for my own boat was:
I like water length for comfort at sea 40 ft or more.
The Triflector Catamaran would probably cost 2 1/2 the cost of the trimaran and I simply don't need all that extra room.

With the triflector trimaran, building and fit out costs are much cheaper and I simply don't need all that extra room for two people.
Plus I cant put a Catamaran inside a container.

The other design shows what can be done with the Triflector Trimaran if you do not need it into fit into a container. Great for charter work? and very inexpensive to build.

Does Brent Martz still have a shed there? He builds very nice boats. (for monohulls ;-) )

Sail plan

Do you have any comments on my use of a oceanic
lateen(crab claw) sail.
The reason I am using such a sail is because it is
very cheap to make (cut flat) and I will be only
sailing downwind (they are not suited to upwind
sailing)
It also allows me to use a short mast(6 meter) which
can easily be lowered.
I also think the oceanic lateen is a very attractive
sail and different from everyone else. Mine will be a
dark red colour.


Most of my sailing experience in the tropics has seen
many days of no wind, flat calm. The wind eventually
comes in at 10-15 knots, which is good for sailing and
then,the wind increases to 25 knots which is not so
comfortable.
A number of my friends have built "sailing type"
catamarans which have no mast or sails, just two small
diesel motors.
They comment that when the sea is flat (for the
wife,of course) they can travel many miles to there
favourite islands/coral reefs in comfort.
They say the high cost of mast/rigging/sails which
they do not need to buy, allows them to pay for many
years of diesel fuel.
These boats use two small diesels 2X 50 hp which are
very economical and they can travel at 9-10 knots
which is a good speed.

I love sailing,but most cruising is always
done down wind. I do not need a daggerboard if I am
sailing downwind, I do not even have a rudder, as I
will probably always have one motor running. (Honda
outboards are very very quiet) however with a sail up
in 10-15 knots I will save a lot of fuel and still
travel at a good speed.
The oceanic lateen allows me to use a short ($200)
mast and a very cheap $200 sail, so I can still sail
and save money and not have to spend $30,000 on a
proper sail rig.
Anyway this is my plan and I can always change.

I certainly would have no issues with something like that Beau, infact looked at a similar style of thing on the first version of mine, which was a very functional design, did not look pretty but was functional.

The financier would'nt let me build that one but let me have fund's for the less functional but prettier design.

Go for it bloke, as long as you don't have to gybe often, i'm sure it'll work fine just like it has on other's before.

I hear lot's of people saying this, but it never (or rarely) seems to happen for me. I appear to have the ability to reverse the South East trade winds, just by turning my bow North West...

How will this affect the motor?

EG: over-reving motor when surfing and extra load on motor attachment point's.

To cat man do, your probably right about the rudder bit, I can mount a rudder connected to the steering for the outboards if I need to.
However the idea is to only sail when conditions are ideal.
The boat is essentially a power trimaran.
I just cant give up the idea of not sailing.(and saving a bit of fuel)
And Sean, you are also were right, it is going to take me longer than four weeks to do the fit out.
In regard to the wind direction bit. That is why Dave and I are both going for power over sail after many years of sailing.
Particularly, when with a multihull you can motor with highly efficient hulls and low fuel consumption.
Power, also gives you more "control" in large seas and a good speed on flat water.
Painting is being done this week, then I will post more photos.

New photo's etc of Beau's Boat
Painting is done, plumbing is in, toilet/shower done, motors in, electrics next week.
should be "IN" in three weeks .
It has been a very interesting exercise which I would like to share with others.
YES it cost more and it took longer (as you all told me)
Even though I have built fiberglass boats before (this boat is aluminium) I have found it very hard to cost, accurately.
I used a professional company to produce the "shell",I was tempted to try it myself but after seeing the professionals in action , no way.
The shell was finished in 4 weeks and the welding was superb.
The painting was expensive (preparation)
I am very happy so far, even though it has cost more.

I did find that MY fitout knowledge was a bit outdated and everytime I went to do something I got the comment that "we don't do it like that any more" but the materials also have improved as well.

This is a "different" boat as I most of you will realise but I am very happy with the fact that the reality is fitting the original concept as planned.

I will keep you all informed.
