Web Site That's All About Building Do-It-Yourself
Small, Homemade Trimarans 16' to 24' long.
by "Dr. Frank" B. Smoot, and
dedicated to DIY
boat builders everywhere!
I live on Florida's "Sunshine Coast"
just southeast of Tampa
Why? Because with our
countless bays, bayous, rivers, lakes, and of course, the
Gulf Of Mexico, it's small boat heaven!

Last - Building Plans
many requests, I finally got off my lazy butt and put
together plans for my best small trimaran design, the
the boat pictured on both sides of this text. For full
details on how to get Building Plans, please go to
FREE Study Plans, simply send me an email
in the subject line.

You'll Find On This Site:
Every boat I've built can be
seen somewhere on this site, in varying amounts of
detail. There are hundreds of
photos on this site - many more than I have taken time to count.

The "Old" Boats
I "discovered" sailing in
2009, and started designing,
building, testing, and (hopefully) refining my designs
within a year.

"history" of my boatbuilding journey from
2009-2011, please click

you can see what I've been up to since the start or 2012.)

Personal Introduction (And "Disclaimer")
I want to make it clear right up
front that I am definitely not a professional
boat builder or designer. I have no training in either
of those fine arts. Everything I know, and everything you'll
see here, is purely the result of trial and error (lots
and lots of error...).So why did I create this site for small trimarans?
In 2009) got
hooked on sailing when a Sunfish blew past my
Then -- after we dumped our monohull
in a lake -- I got hooked on the stability of multihulls...
Then I discovered that the trimarans I
could build were both quicker and more stable than
any of the catamarans I had previously built.
And of course, any sailboat that goes 12-15
mph, sits flat, handles great, rides dry, takes 10-12 minutes
for one person to
assemble and rig, and costs less than $1000 to build --
well, it just can't
Note: This site will be updated as often as
there's a good reason to do so. And If you are building a
small trimaran, but you don't want to create your own web
site, I will be happy to create a page on this site
dedicated to your project -- your own videos, photos, story,
the construction detail photos you'll find here...
Although I have a ton of
construction photos of every boat I've built, I haven't
included some of them on this site as yet. I thought it would be best
to wait and see what you are actually interested in looking
at before I upload the rest of them.
But right now you can find
more than 120 photos related to just two of the dozen plus
boats detailed on this site - Item #2 (A
Brief History) and Item #6 (Laura's Ultralight Trimaran).
You'll find both of those items listed at the column to the
If there's any other boat on
this site whose construction details you would like to see,
please email me
and let me know, and I'll get them uploaded for you ASAP.
Happy building! - "Dr. Frank"
