Angus Rowboat & Sailboat Kit

The Angus Rowboat / sailboat was featured on smalltrimarans awhile back on this page. The kit plans for this boat (including the added double outriggers) can be found on the following pages at Duckworks:

The basic RowCruiser kit can be seen here: https://duckworks.com/rowcruiser-angus-rowboats-cruising-rowboat-kit/?mc_cid=cf9e9af233 (more…)

Identify this Trimaran in the UK?

Would be trimaran salvager Marcin S. asked what trimaran model this might be? Which would also reveal who designed it.

This boat is currently abandoned on a shoreline in Cornwall, UK.

This is a great question for outsourcing to the small tri community.

What I’m pretty sure about is that if Ross Poldark had spotted this boat, back in the day, then he would have salvaged and restored it for sailing enjoyment at his home by the sea in Cornwall :-) (more…)

Outback Mike’s Double Outrigger Canoe Adventure

Small tri friend Hien Ngo sent me the following info regarding a unique double outrigger canoe historical project / modern adventure. A fellow called OutBack Mike put a lot of time and effort the canoe-build and subsequent expedition, as seen below via vids on YouTube.


I’ve never heard of Outback Mike before. He appears to have some bona fide skills when it comes to this sorta stuff though. (more…)

Attempt to Cross the Atlantic on a Kite-Powered Small Trimaran

Portuguese kitesurfer Francisco Lufinha is prepping to cross the Atlantic in a trimaran. His target time-frame for this adventure is November 2021.

“Francisco Lufinha aims to cross the Atlantic Ocean on a trimaran powered by a kite.
The experienced Portuguese kitesurfer adapted a multi-hull boat that is able to sail the rough sea using a towing kite propulsion system.

Lufinha hopes to leave Portugal and arrive in the Caribbean three to four weeks later, depending on the weather and ocean conditions. (more…)

Mini Trimaran (from B and B Yacht Designs)

Smalltrimarans.com reader Chris L. sent me the link to the new “Mini Trimaran” from B and B Yachts. It’s a double outrigger canoe. (Perhaps designed with camp-cruising adventures in mind?)

The webpage for this boat says, “It combines elements of the successful Expedition Sailing Canoe and the “kayak trimaran” named ‘Spongebob’ into a new vessel.”

We previously posted about B&B’s Expedition Canoe here and the Spongebob kayak trimaran here. (more…)

Kanka 14 Trimaran Now Available

Small Tri reader Barry N. emailed to let us know some more info about the Kanka 14 trimaran was now available. (Thank you Barry!)

This sailboat is a new model from Yacht Design Collective in Morbihan, France.

We posted info regarding the Kanka 14 last year here.

The main webpage for this boat can be viewed here. But anyone interested may directly contact their team and receive additional information, including PDF documents. (more…)

1983 Micro Multihull Design Symposium Documents

Some readers will want to check out the following download document with info from the 1983 Micro Multihull Design Symposium. Sailing friend Tony Basso shares the below link with us.

Tony writes: “It’s old but contains some interesting stuff if you’ve never seen it.”

Many thanks to him for this link: https://multihull.org.nz/wp-content/uploads/2019/07/micromultihull-design-symposium.pdf

Making Amas with Polystyrene Foam

Linked image from the referenced webpage at Instructable.com

A lot of folks these days are making very small boats, such as kayaks, with expanded polystyrene foam, covered with fiberglass and epoxy. What is more of interest to many small tri builders, however, is the potential use of this building method for making lightweight amas. (more…)

Trimaran Sailing PDFs

Sailor David H. recently shared the following links. One can either open or download the PDF docs in their web browser, which contain some good info specifically related to sailing trimarans.

Many of our readers will enjoy perusing these publications, found at the following websites:




Astus 14.5 In Development

Sailor Pedro Ortiz sent me a link to the new Astus 14.5 trimaran. Pedro himself sails an Astus 20.1 trimaran in NW Spain. (Many thanks to him!)

The new 14.5 will apparently be a bit different from their original 14-foot design from years back – the Astus 14.1. We certainly look forward to seeing it in production and on the water.

All the best to Astus (and marine businesses everywhere) as they try to navigate through this year’s craziness. (more…)

Libertist 703 In Production

We first posted about Libertist trimarans here. One of our readers just emailed and said the Libertist 703 has now followed the larger 853 model into production.

This boat appears to combine some unique features. We’re looking forward to seeing a video of it under sail.

A couple renderings follow, which are linked to at their locations at the Libertist website: (more…)

Getting Squirt Ready to Sail

Sailor Eric Dahlkamp’s self-built “small-Weta-wanna-be” boat he named SQUIRT is just about ready to splash. All I can say is, “Wow,” when it comes to seeing the images of this boat as the building progressed. We first saw it here.

Even though Eric’s build took many unconventional twists and turns he ends up with an amazing-looking craft. He comments a bit below, but the photos really do the talking.

Eric’s work gives all us self-builders high goals to shoot for! Be sure to scroll all the way down and view ALL of the pictures … PLUS 2 videos.

Again, I say, “Wow.” (more…)

Intro to Foam Core Boatbuilding

The following video was posted by Cerny Yacht Design and features their foam core boatbuilding method. This method appears to result in hulls that are both lightweight and stiff.

Another advertised benefit is the ability to create nicely shaped, rounded hulls, if desired.

I’m curious if any of our readers have used this method. If so, then please briefly share in the comments area below, including whether or not you think the result was successful, and whether you recommend it or not as a boatbuilding method. (more…)

New Seaclipper 24 Trimaran Now Sailing

Sailor / self-boatbuilder Jeremy Gage shares the launching of his Seaclipper 24 trimaran with us. He pushed through the tough sledding often associated with building a boat of this size.

Previous posts on the 24 can be seen here and here. And click on the images below to enlarge them.

Congrats to Jeremy for his successful build. Now he gets to enjoy the rewards of his work and investment of time and money. Plans for the Seaclipper can be obtained from the designer, John Marples. (more…)

Seaclipper 16 OC (Nearly Finished) for Sale

Possibly interested in finishing off a nearly completed Seaclipper 16 OC? Sailor and experienced self-boatbuilder John Goley is willing to part with his to the right person.

Why? And who exactly is this “right someone”?

Read on.

The following is a summation of John’s story. Someone is going to benefit from his skills, equipment and nearly finished boat-build.

Be sure to check out the temporary website he set up in order to illustrate pics and info for everything being offered. (Link follows below, which includes John’s contact info). (more…)

DIY Trimaran Self-Tacking Jib

Full view

Sailor Jim Gallant has built a self-tacking jib for his reconfigured DIY trimaran. Go here and then here for the backstory of this particular boat if you’re not familiar with it.

Jim decided (in agreement with some others who’ve seen the boat) a self-tacker would be a nice addition.

Jim writes:

“Used a friend’s bender to bend the 6′ long mainsheet track from the Supercat 20 used for my vaka (see pic of green Italian machine). I went for the 2-line design where one line goes forward to tension the jib’s shape, and the other pulls the car on the curved track towards the centerline of the boat. (more…)

Wavewalk No Longer Offering Folding Outriggers

As a follow up to the previous post, here is a discussion against adding amas to a kayak known as the Wavewalk. The Wavewalk is billed as “The World’s Most Stable Fishing Kayak, Microskiff, and Cartop Boat.” The developer used to offer outriggers for one of it’s models.

They stopped offering outriggers for the fishing kayak because of the following reasons (directly quoted below) from their article found here:

  • Extra drag
    Typical outriggers are several times shorter than the kayak’s hull itself. This means that as the kayak moves, the outriggers move at speeds that are many times higher than their own hull speed (Froude number). This generates a disproportionately large amount of Residual resistance (Rr) as well as extra Frictional resistance (Fr)
  • (more…)

Thoughts Against Adding Amas

A couple years ago I had a short discussion with a well-known multihull designer about the advantages and disadvantages of adding amas to canoes and kayaks. During our discussion he told me that sailing canoe aficionado Hugh Horton seemed to be generally against it.

Hugh is known for designing canoes such as the Bufflehead. See here for another article about Bufflehead. (more…)
