Home Built Trimaran: the Scarab 650

Slow progress..still it is progress.

After using the router on the full length of the rudder I thought it was easier to use a mould to get the right shape. Using the router on the full length, I saw some irregularities occur. We don’t want that! Luckily not to late the change strategy.

This mould would be placed over the rudder and with a longboard connected to the router, the shape could be made easier, quicker and more accurate, just by sliding it back and forth over the mould.

While using the router it is dusty and noisy so, gear up and use a mask, goggles and ear protectors.

After completing one side of the rudder or daggerboard, the mould would be used again for the other side since a made the mould to rest on the flat workbench.

after this stage, the raw shape will be sanded, filled, sanded to a smooth surface.

to be continued..

Daggerboard part one

The project is on its way. I started with the daggerboard. It is a build-up retractable daggerboard made out of two plates of plywood joint together with a glass fiber core.

This core is of two layers of traxial 830g/m2 cloth. The plans actual indicate that 750 g/m2 is sufficient for the job, but I only could get my hands on 600 or 830, so I chose the latter.

The epoxy I use is from West Systems. I like their dispensers and the way you can make fillers and glue with their additives.

When the daggerboard was joint together and fully dry I am making the daggerboard shape with a ‘router’ and using the templates as provided with the plans. I can’t get the grin of my face while working: I started working on my first boat!

Once the general shape of the daggerboard is finished I will use a belt sander to remove the small discrepancies.

April 2018..Here we go!!

I started a new project. Building a sailboat.. actually THREE sailboats.. ‘cause that’s what you’re doing if you’re building a Trimaran.

The trimaran I selected to build is a Scarab 650, designed by Ray Kendrick of “Team Scarab Multihulls”.

I had the plans in my possession for over a year and studied them extensively. Since Ray has made multiple designs, I contacted him for a little help to select a suitable design for my first build. Ray was very helpful and I followed his advise to build the 650.

The design will be build by the “stitch-and-glue” principle and I will build the boat from marine grade plywood and glass epoxy.

There is the possibility to build the 650 with foam epoxy, but since I am more familiar with woodworking, the first option “feels” to exotic for me and it is a little bit cheaper to buy.

Since building a trimaran is a large project, I try to start with the smaller projects to get in the “flow” of building. As there are building the rudder and the daggerboard. For both there is woodworking and glass-epoxying involved.

Building a Scarab 650 Folding Trimaran

by Small Tri Guy | Jan 30, 2015 | Self-built Small Trimarans , Small Tri Info - All | 3 comments

In this post sailor Fran Sneesby shares a little about the Scarab 650 trimaran she is building. The Scarab 650 is another fabulous-looking design by Ray Kendrick .

Fran works with Ray and has already built a couple of these Scarab boats. She is particularly keen on the size of this one though (see below). Thanks to her for sharing here!

………………..

My father sailed skiffs in Sydney and one of my earliest memories is hanging out in my uncle’s boatbuilding shed in Sydney. I learned to sail when I was young and it has been the passion of my life.

I was introduced to small tris when Ray Kendrick came to stay with me in Queensland. He was busy designing trimarans and was convinced that he could design attractive boats that were easy for a home builder to complete without having to purchase any specially manufactured parts.

In the past we have spent up to two weeks camping out on a similar boat Scarab 670 and we race it many times. I have faith in Ray’s designs and I am sure this one will perform well.

I wanted to build the first one but I was beaten by Dani in Sweden. (Photos of Dani’s yellow boat are shown here). He built a beautiful boat and is well pleased.

Dani’s Scarab 650 trimaran was the first one built

I am about half way through building the boat with the floats, beams, rudder and centreboard complete. The main hull is ready for the bulkheads to be added.

The following pictures are ones of the composite boat that I am building…

Is there any scarab tris for sale?

What is the cost to build the 650? Do you recommend epoxy or polyester resin.

I am building the 650 in Brazil. Se do not have all the material available in Austrália, but the Hull is receiving the main beams at this time, and till now I didn’t need to ask advice from Ray. Very easy building in plywood.
