Tamanu Pictures

I put my Tamanu up for sale a couple of days ago and got a request from a potential buyer for some pictures. I put the boat together with the foils, akas, and amas but didn’t have time to get the mast and sail up due to an approaching thunderstorm.

I have to say after see her setup I have very mixed feelings about selling her – especially at the low ball price I set. In her current state she should be worth at least $5000 and if I finished her maybe $10000. She really looks good and I think will be a great WaterTribe boat for the EC or UF.

Tamanu Rear Storage Area

Notice there is a floor with a Hobie hatch. The intent is to use a waterproof duffle with tie downs sitting in this area for stuff I might need while on the water. The compartment under the hatch is for a battery or other stuff that would not normally be needed while on the water. The tiller swings back and forth over this compartment. The floor is above the waterline and you can see drain holes at the forward end of the space.


Tamanu Center Cockpit

The center cockpit also has a floor with Hobie hatches. There are two hatches because there is a bulkhead under the floor. Depending on other choices you make a tractor style seat similar to the Kruger Dreamcatcher could be placed above the Hobie hatch at the rear of the cockpit. But many would prefer to have hiking benches or trampolines which would be easy to make and install.


Tamanu Forward Compartment

This is the forward compartment. Just like the one in the rear there is a floor above the waterline and a Hobie hatch. There are drain holes at the rear of this section. Again it is intended to have a waterproof duffle with a tie down system to hold stuff needed on the water. Longer term storage is below.


Tamanu from the front. She is very slender.


Tamanu with aluminum akas installed

The aluminum is from NRS and is the same stuff used in their whitewater rafts. It is very strong and there are lots of fittings that can easily be added. For example, oar locks.

The akas are lashed to the center hull

Obviously, this is just a very quick way to lash the akas to the boat. A real lashing would use about five loops before being tied off. I have had very good results lashing akas and amas over the years.

Also, there are some really cool options for doing the akas that we can talk about.


Tamanu with Classic 16 Big Ama Attached

Wow! Doesn’t that look cool! My Classic 16 Big Amas are so much better than the original wood designs (in my oh so humble opinion).

Tamanu Bottom

The bottom has a funny look because there are layers of fiberglass tape that were smoothed out using low density filler. At one time I was going to put a layer of kevlar. Might not be a bad idea depending on intended use.

That’s it. I am really trying to figure out if selling her is such a good idea.

There is still plenty of work.

  • All rigging is needed
  • Mast needs to be modified to sort of be like a Hobie mast
  • Rudder head needs finishing
  • Akas need just a small amount of work. Also, might want to consider something like Jim Brown used in his latest design.
  • Side seats should be strongly considered.
  • Other stuff too depending on your needs

Tamanu – Leeboard Pivot

I’m back to finishing up the Tamanu. Today it was time to install the leeboard pivot. It’s pretty simple. Just drill a hole, install the bushing and stick a pin through the whole mess. Of course, when I do a simple job it takes several hours.

Use a jig to get a perfect hole for the bushing.

Tamanu Modifications – Cockpits

The Tamanu is a great design for a small single or double outrigger. It is possible to modify the design as needed to suit each builder’s needs.

I decided I wanted self bailing cockpits and more of them. I also wanted plenty of below deck storage for items that typically would not be needed while at sea. I also wanted plenty of storage that was easy to access and did not require the hatches to be opened while at sea.

So I put in a floor well above the high water mark with drainage holes for each section. I used Hobie kayak hatches for below deck access. I divided the Tamanu into three cockpits. I sealed the bow and stern sections.

Tamanu 3 Cockpits

You can see that there is a bulkhead between each cockpit. If I take a wave over the bow it could easily enter the forward cockpit but there are drain holes to self-bail. Also, most of the forward cockpit will be filled with a waterproof duffel to limit the amount of water actually in this section.

Forward Cockpit

Note the really nice Hobie kayak hatch. This also shows the forward aka mounting points and the mast step tube. Not shown here are the two drain holes at the aft end of this cockpit. Remember that this space will be filled with a waterproof duffel. Alternatively I could use a canvas cockpit cover.

Long Center Cockpit

The center cockpit is long enough to sleep in and has two Hobie kayak hatches. Below deck there is a bulkhead between the hatches. The self-bailing holes are in the center of this cockpit. I do intend to have a seat at the aft end for really bad weather. Also, I can add a cockpit cover, but I probably won’t because it is self-bailing and a cover would add a bit of hassle. There will be a tarp for camping though.

Aft Cockpit

The aft cockpit with its Hobie kayak hatch and showing the aft aka mounts. The self-bailing holes don’t show up in this view. Again this cockpit will normally have a couple of smaller waterproof duffel bags that will help if I take a wave over the stern.

The Tamanu is a very skinny boat but these self-bailing cockpits combined with plenty of below deck and above deck storage will allow long cruises. She should make a pretty good WaterTribe boat for the Ultimate Florida Challenge, Everglades Challenge or the North Carolina Challenge.
