February 16th, 2015

Smalltrimarans contributor Ian McGehee sent me a YouTube link to the following video. The builder of this boat calls it the “Endorphin trimaran.” The video is basically a collage of the building pictures for this boat.

I really like a couple of the techniques used to assemble this craft. The crossbeam holders on the vaka, for example, look pretty neat. It may be applicable to other smaller tris. Read the rest of this entry »

Double Outrigger Sailboat in Popular Science Magazine (August 1949)

February 5th, 2015

We’ve previously seen ads for outrigger sailboats in decades-old issues of Popular Science and Popular Mechanics. Here we link to a full article from 1949 that shows how to build a cartopable small tri.

It’s pretty neat, especially considering the time period. I love stuff like this, partly because it’s reminiscent of a pervasive “can-do” spirit of a bygone era. It’s old-school. Read the rest of this entry »

WindRider Launching New RAVE V Hydrofoil Sailing Trimaran

December 9th, 2014

The following press release (and short promo video) for the new RAVE hydrofoil model was just sent to me by Dean Sanberg, President of Windrider. I am reprinting the release here below in its entirety.

I’ve heard many times the original RAVE, produced and sold back in the 90s, offered an exhilarating thrill ride. It’ll be good to hear from sailors how this boat performs under sail. It’ll also be good to get feedback regarding durability and setup time for a trailered boat on a launch ramp. Read the rest of this entry »

Nicholas has named his new craft VOLTAIR. It has turned out to be just as unique-looking as SegalKajak! Perhaps even more so. Read the rest of this entry »

How to Build Rudders or Dagger Boards

October 30th, 2014

Multihull designer Bernd Kohler shares his method of building rudders and foils in this short article. The post about his first ever small trimaran design has generated a lot of interest and I am very glad to be able to spotlight one of his time-saving building techniques here.

Please keep in mind, as you read, that English isn’t his first language. I did very little editing of the words below; I think he does a pretty good job at communicating the concept and instructions. I hope lots of folks are able to glean from it and, hopefully, at some point, save a whole bunch of time when making pieces like this. Read the rest of this entry »

A Fast Little Tri On An Economical Budget

It appears to be a fast, light boat. And may be of particular interest to anyone who’d like to build a small tri on a budget. Read the rest of this entry »

Skin On Frame Trimaran Anyone?

October 17th, 2014

I’ve become fascinated by the “skin-on-frame” building approach lately. I’ve found one (very unimpressive) skin on frame trimaran on the web. Although I have found a few single outrigger sailing canoes built in skin on frame.

Check out the following (very impressive) “Great Outrigger Sailing Canoe,” which is found on this webpageRead the rest of this entry »

A-Cat Hull Used for Trimaran

Chris Ostlind is currently building a new small trimaran that sports a main center hull taken from a beach cat. It looks great. Below is an actually picture of the boat now, as it’s being built and also a “mock-up” photo of what Chris envisions it will look like on the beach when it’s finally finished (and repainted).

More Best Guess Trimaran Updates

September 10th, 2014

Trimaran builder / sailor Jim Gallant has tweaked his trimaran (named “Best Guess”) once again. He has created an excellent resource detailing the work on this boat at his webpage.


Overall, Jim said he is pleased with the results, although he does miss one feature in particular. He writes, “[Regarding the boat’s] performance, it’s different. In most ways better but some ways not. We had it planing before last winter’s changes. It was lighter and I think the flat transom allowed it to ‘break loose’ in high winds like a high wind windsurfer does. I have seen plenty of bottom paint above the water surface in high winds this summer, but I don’t think it’s sat fully on top of the water as it had before. Read the rest of this entry »

September 3rd, 2014

Windrider has just Signed a deal with Astus Boats to sell their trimarans in the United States. The online version of the marine industry magazine, “Trade Only Today,” posted this news a few days ago (on August 27th).

What’s It Like Getting Boat Hardware from Duckworks?

August 21st, 2014

Just over a week ago, I placed a pretty sizable order for boating hardware at Duckworks. Their prices are very good and I’ve purchased stuff from Duckworks several times in the past.

The proprietor, Chuck Leinweber, promptly mailed out my package and a few days later it came in the mail. Somehow, the USPS had managed to tear a big, gaping hole at the top of the package, allowing half of its contents to spill out during transit (including blocks, pad eyes, shackles, etc).

Road Rash Plywood Trimaran Design-Concept

July 30th, 2014

SmallTrimarans reader Chris Ross recently sent me the link to a trimaran model named “Road Rash.” This model appears to still be in the design-concept stage, as there are no pics of an actual boat that has been built yet.

The Road Rash is designed to be 7.5 meters (a little over 24 1/2 feet) in length and constructed mostly from 6mm plywood. The info page says the crossbeams would be foldable for trailering purposes. Read the rest of this entry »
