View Full Version : Micro Skiffs plans and foam construction ideas

12-03-2016, 01:09 PM
Looking for direction to any previous threads if available.

If not does anyone know anyone building these hybrid boats, kinda a cross between a large Paddle Board and a micro skiff.

All responses welcomed.

thanks in advance

Micro skiff? What exactly is that? Ignorant and curious.

You might try www.bateau.com They have plans for a number of "flats skiff" types and duck boats. Thee are several there in the 12 to 14 ft range.

Well I'm just learning about them myself. Seems like they can be over sized Paddle Boards that take an electric motor up to small skiffs that are almost all decked.
Some look like a cross between a kayak, a paddle board and a small skiff but all use motors. They are used mostly for fishing in shallow water.
I'm trying to find out if anyone is building their own and using foam.

Here is a Duckworks article about a foam Jon Boat build, http://www.duckworksmagazine.com/16/projects/toadboat/index.htm. I had large concerns/reservations when I first read this article. It's been growing on me a little more over time.

For those that are wondering what a micro-skiff looks like, a commercial example of a micro skiff is a solo skiff, http://www.soloskiff.com/

I don't have any experience yet, but I'm considering using the techniques mentioned in a letter here, http://duckworksmagazine.com/2016/11/letters/, for different purposes than your goal. The full description of the sandwich technique interview can be found here, https://intothemystery13.com/ultra-light-weight-foam-construction-technique/

I just bought some from and screening material for performing some informal load tests of square beams and flat panels using the EPS foam with aluminum or fiberglass screening. For boat purposes, I was thinking about using multiple coats of thinned Titebond II, ala Chief from the Duckworks list. For my specific purposes, Titebond will flex more than epoxy will.

I'm just dreaming/scheming. I don't have any experience yet.

I've been thinking about building one similar to a plywood paddleboard I built a few years ago; 3mm plywood/glass sandwich skins vacuum laminated to an eps foam core. I could extend the sides up above the deck maybe 4-6" to give some freeboard, then make the transom mostly open for an unsinkable craft with a self-draining deck.

When I made the paddleboard, I built a simple particle board rocker table for the bottom shape, laminated the bottom panel and inner skin to to layers of 2" construction grade eps, then laminated the top panel and inner skin, then removed the excess foam on the rails and clamped/vacuum laminated the sides. Finally I cleaned up and rounded all the plywood joints and hand laminated the top skins.

The paddle board did not require stringers but a micro skiff would probably need some, they could be incorporated into the motor bracket.

The eps sandwich is very strong even though the foam core is very weak. Eps does have a lot of air space in it and requires a vent to prevent the skins from delaminating when the board heats up in the sun. The vent is just a hole that lets air into and out of the core. I used a commercially made surfboard vent with a goretex membrane. If you had a storage box similar to one on the solo skiff, you could probably just make a small hole leading to the core somewhere inside of the box, as long as the lid was not airtight.

finished weight could be well under 100lbs. My 12' paddleboard is wide enough and has enough volume for my wife and I to use as a tandem, and it weighs 40 lbs.

A 150 pound thirteen footer is a micro skiff?
O no ...this, is a micro skiff

Hey,. all great feedback guys, keep it coming.
The solo skiff is the closest I've seen to what I think I want, so far.

How are the experiments going with the foam and fiberglass screening?
I going to try similar experiments using Glidden Gripper which is, I believe, waterproof.

Before I use this foam and screening to do a micro skiff I am building a 40" wide x 12 foot long set (3) of pontoons with a deck. Actually it will have two outer pontoons that are 12" x 12" x 12 ft and a center pontoon 12" high x 6" thick x 10' long, this one will act as a keel for turning and for additional bouyancy. It is designed to fit inside my B3000 pickup bed. The center pontoon will be two feet forward of the outer pontoons leaving two feet for the outboard lower unit when tilled forward. the plan is to carry this in my pickup with the outboard on and push back against the cab. Saw a few micro skiffs with this idea.

I think there were some good links in the low power planing boats thread.

I know this doesn't have to do with the boat, but I had to ask. Is that a International Harvester truck behind the Tipsqueek? It looks like a R series model 110.
