Progress On the Tiki 8ms

I have been very busy here lately and have a lot of photos of the Tiki 8m in progress.They aren't all in exact order but will illustrate the process. The companionway hatches are right and left handed, unfortunately we only got the mold for the port hull. We will have to build a mold for the starboard side. This photo shows the hatch mold with gelcoat applied.


The masts have been delivered to us and are ready to be stepped and rigged.

This hole is for the forestay bridle.

These are the beam lashing cleats. We have over-drilled the bolt holes and packed them with high density filler and glass fibers. These bolts go through the hull/deck joint.

Below are the beam locating blocks. they are made of Coosa board. This is a high density polyurethane foam reinforced with fiberglass fibers.

Here you can see we have prepped the deck areas where the beam locating blocks will be bonded.

Here the blocks have been glued down to the deck. We used epoxy to attach these blocks for it's superior strength and secondary bonding characteristics. After the epoxy kicks we will fillet the blocks into the deck with polyester putty and gelcoat. Then we will sand and polish them for a smooth finish.

We built these beams from divinycell foam and unidirectional glass fibers and carbon fabric.

Below you can see the flange that will support the cockpit. We have also started to build the brackets to support the jib winches.

Where ever hardware is attached to these beams we must "pot" the fastener. This entails overdrilling the fastener and filling the area with a mixture of hi-density filler and glass fibers.
The pots for the mast step bolts are visible here.

This photo shows the winch brackets and the pots for the mainsheet traveller track and the cockpit support flanges.

In this shot we are gluing the beam locating blocks onto the bottom of the beams. First we had to align and level the hulls.Then we put thin spacers in place to achieve the desired clearance. Then we apply epoxy and clamp the beams in place and clean up the squeeze-out.

Now we can lash the beams in place. We are launching this boat in an incomplete state so that we can verify everything is just so before final paint. These two boats have been modified from the original design in several ways and we want to be sure that everything works perfectly for our customer.

One of the modifications required is that the boat must maneuver in reverse under power in tight quarters.This is not one of the Tiki's strong points. In order to accomplish this we have removed the skegs and are fabricating kick-up rudders. This will enable us to size the rudder for adequate turning force and allow us to put some counterbalance area forward of the rudder shaft. This is much more complicated than the stock rudder design but is what our client requires. Here we are working on the upper end of the rudders. One of the lower blades is visible on the bench under the grinders.

These rudder parts are built of Coosa board and then sheathed with carbon fiber.

The upper parts of the rudders, the cases, are drilled for the lashings. These are potted just like holes for hardware.

Here we are using pvc pipe as a form for the tiller receivers.

We are using a square and a level to drill the holes in the stern post for the rudder lashings.

These holes go through solid glass and don't need potting. The are painted with gelcoat to seal them and are then sanded and polished.

Here the rudders have been lashed on and a blade has been inserted.

Here we are gluing in the gussets under the deck below where the mast beam is attached. These gussets will help prevent wracking from the mast loads. Under the aft beam attachment is a structural bulkhead that provides support.

Here we are gluing in the ash staving for cabin ceiling.You just can't have too many clamps.

We have made some teak ladders for cabin access.

In the meantime we have also been working on the cockpit.

In addition to the normal cockpit these boats have an aft station for the captain. Here is a view of this part upside down in progress.

We have now added glass to the bottom of the captain's station.

Here is the topside view of the captain's station showing the foot well and the pots for mounting bolts.

In this photo we have just glued the window into the frame. We use Sikaflex for this. The small blocks are super glued to the paper film on the acrylic to hold it in place while the first application of Sika dries. In the morning we will remove the blocks and top off the Sika and tool it for a nice smooth finish.

We have now brought the boat to our local municipal ramp for launching and sea trials.

Here she goes!

Around the corner to the beach and up with the mast and on with the sails.

We have some adjustments to make but she moves along nicely and we are very pleased.
