Hi Burk
I have the plans. The maximum sail area should be 2x8 square meters.
I'm shopping aroun right now and would say that for a new rig the cost
is around 1200 Euro if not buying top notch stuff (one can easily go
over 2000 Euros).

hello Burk,
The costs of the sails depents in which country you have to order them.

Optimum sail size between 8.3 and 8.9m2. We have an e-commerce address
in Germany. The ask for a 8.3m2 sail Euro 358,-. The send the sails to
any destination in the world.
The mast position is correct for the modern sails.

Hi Bernd,

here comes the first of my stupid questions(many more to
follow..hehe.
What the heck is a linear sander?

We (my wife and I) built 13 boats so far. Lets talk about sanding.
One of the works which have to be repeated often when working in

the

wood/glass Epoxy system and even more so when working with foam
sandwich system.
The most important tool is a very good sander. Epoxy gets

thermoplast

again above about 75 degree Celsius. Which means, when you use an
ordinary oscillating sander which vibrates 20000 times or more a
minute and the wrong sanding paper, the only effect you get is

clocked

sand paper.
So which sander is the best for this ?
We use a linear sander which has a 5mm rotating movement and a
rotation speed between 2000 to 6000 revolution. As sanding paper we
use Aluminum oxide paper (grain 85 and to finish 120).
This sanding paper will not clock as easily as normal sanding

paper.

It last about 8 times as long also. By the slow rotation of the

sander

the Epoxy will not get thermoplast . This machines work whit

almost no

manual pressure. The are not cheap but worth every penny.
The relative new orbital sanders are not bad also. But you have to
hold them absolute parallel to the working surface. Otherwise you

get

immediately marks which have to be filled again.
Preparing a perfect putty will help also to easy the work. This

will

be a story for an other time.

Hi Pat,

here?s for your log:

Wolfgang Bunjes
Duo 425 (final fase of construction)
Sailnumber? well, i think that i didn?t receive any
plans purchased in april, i believe
Location: Florianopolis, Santa Catarina, Brazil

I also own now the set of plans for the DUO 800, which were
originally ordered by Helmut Scheithauer. He?s still working on a
Tiki 29 or whatever and in a deal about some equipment we traded
the plans. Will build next year. Sailnumber also unknown!
fair winds
Wolfgang

hello,
I'm going to order the DUO 425 plans and i want to get an idea of the
costs of the sails, masts etc. Can anyone tell me the size of the
windsurfing sails used on these boats?
Is the boat balanced around the older triangle style rig or the newer
rectangular style rig? or both

Thanks,
Burk

Hi Paul,

I set you up with two separate listings since you have two plans.
We are only 5 hours away by driving time.

3. Eco7 March 2005
Economy Cruiser June 2005
4. Eco7 - began June 2005, not completed
Economy Cruiser - not started (may be built later for my son)
5. No sail numbers

Charles,
I was able to translate your site by right clicking and using ghe
Google Page Translator. Very nice site. Thanks for letting us know
you had that set up.

Charles,

Thank you for the information. I will be very interested how you
set up the rudders and the Cassette. I want to the same on the 860.

3. I do not have a Sail Number or maybe I lost it?
4. Purchased Plans Aug 1st, 2005
5. Have not started building vessel
6. Location: Canada, Quebec, moving

About the P95 design:
I really like this design, it is a perfect bridge between a beach
catamaran and a world cruiser. I also considered the following

designs:

Stiletto 30
Naval force 3: Piana 30
Malcolm Tennant: Portage 10
Schionning: Radical bay 800 (it is closer to a Duo-800 )
Kurth Hughes Sailing Design: 30' Catamaran
Kendrick: Siren 950
Woods: Windsong
ADN-Levievre: 4xcat 28 (very close to the P95)

But in the end, the ease of construction and the quick build time
were the major points that led me to choose the P95 design. Also I
really like the asymmetrical hulls and the overall simplicity of

the

design. It is an modern Manu Kai catamaran

This is going to be my first build but I am planning to include

some

changes in the design:

First and major change, I will keep the bulkheads and structure in
wood but the exterior hull and deck will be in Corecell foam with
vinylester resin instead of marine plywood

I want to have a kick-up rudder system. Probably with a cassette

and

include some stairs on the rear transom

I will include a bowsprit and redesign all of the front aluminium
beams and have it professionally built.

I will change the outboard motor bracket from wood to aluminium.

About me:

I have been sailing beach catamaran for more than 10 years and I

used

to be windsurfing as well.

I did work in many shipyards on repairs, conversions or

construction

big commercial ships: Ore carrier, ice breakers, tugs,

commercial

fishing boats, aluminium RIB.

I have a weblog but it is in French so far. Once I start to work

on

the P95, I will translate it to English

Hi everybody,

My name is Wolfgang, german multihull sailor, living in Brasil on the
island of St. Catarina( about latitude S27?30??)At this moment i?m in
the fina fase of building a DUO425, which is my first boat building
experience. and what an amazing experience it is - i just love it.
So i?m very pleased about the founding of this group and hope for
interesting discussions and idea sharing.
Fair winds to you all
Wolfgang

I have a major advantage. I manage a mini-storage so there is
always space for workshops and projects. This is what has made it
possible to take on the building projects I have going.

Hi, I'm Paul and I bought plans for both the economy cruiser and

I have been working on the Eco7 sporadically for a little over a
year. Bernd drew up a set of antivortex panels for the Eco7. I
like the simplicity of them and will be interested to see how

well

they work.

This is one of 3 boats I am working on, the other 2 being a

Bolger

Super Brick and a Sam Devlin Winter Wren whose hull I am

adopting

from another builder. Obviously I like wood working as well as
sailing, though for now sailing is limited to a pair of small
dinghies on Lake Lanier (near Atlanta Georgia) until one of

these

beasts gets finished.

Each boat as well as being very different in design is for a
different purpose. The Eco7 and Winter Wren will live in the

Ocean

and the Super Brick will stay at Lake Lanier as a weekend

retreat.

Among my talents are videography and I am making video diaries

of

each of the boats which I will make available as they progress.

So do I, but first have to find someone who will shoot it. However, if
I make another video, I'll upload it to the files section.
