I used an old mast section on my Tiki riged Hinemoa and made holes in the netting large enough for the bridle to pass through without chafing, for the aft netting beam I used the lower section of a laser mast. I liked being able to stand on the beam in front of the jib. On our Tiki 30 we used an old boom of a yacht as a aft netting beam and held it on with lashings.

I was looking back, and this is probably the best photo I have, although it was taken before I installed the boarding ladder in the center section.

<p>Having grown up with 3 generations of family in the Pac. NW lumber and timber industry dealing with Fir Cedar and Hemlock mostly I never imagined bamboo would be a consideration let alone available around here. I love the idea of bamboo. Still have some issues to figure out but it's high on my consideration list.</p>
<p>Thanks for the info,</p>

Untreated bamboo will loss its colour quite quickly, going from green to grey in less than a week. Leave it in the sun and it goes an unspeaking bleached grey. To help preserve the bamboo and enhance it's beauty, wait until all the green has gone and try taking some dark coloured decking stain and very sparingly apply it only using the very tips of the brush. With a little practise you can apply a very realistic grain effect that really brings out the beauty of bamboo. Adding extra…

I used this effect on a bamboo fence and it looked great when finished and still looks good 3 years later.<br />

<p>Both these Ideas from Randall and Ralph give me an idea. The Bamboo is appealing as the stern beam. I like the aesthetics but it would create issues with the front beam that supports the headstay. I also have never noticed Bamboo that size here in the Pacific NW, not sure how hard it would be to find it. Changing the headstay to attach to a bridle changes geometry of the jib location.

Placement of a bridle on the Pahi bows would move it aft from the original location, on the beam, which is very far forward and quite elevated on those Polynesian bows.</p>
<p>I had never thought of galvanized but it's definitely worth some analysis! I now have specs for aluminum from Hanneke so I should be able to find a comparable size in galvanized and see how the weight compares. Galvanized steel would also allow me to keep my custom made Seagull striker support making less work than creating a new bridle attachment.</p>
<p>Bamboo stern and galvanized bow might be the answer, Thanks Randall and Ralph for the ideas,</p>

<p>Have you considered a galvanized steel pipe, plugged with epoxy putty at the ends and painted? Considering how much stronger steel is compared to aluminium, one will get away with a smaller diameter and wall thickness. The weight difference will not be that much on a 3.8m length. Price and availability speaks for itself of course.</p>

<p>Frank,</p>
<p>For aft netting, boarding ladder and solar panel support on our Tiki 26, we used bamboo. It was very light, very strong and very free when I asked a neighbor's permission to cut a single stalk from his yard in exchange for cleaning out some dead bits. I can't comment on the durability just yet, but given the replacement cost, I'm not too concerned. The span was about 10 feet, diameter was about 3 inches, and the variety was "Painted Lady"...very attractive at first, but lost…</p>

I just heard back from Hanneke about aluminum dimensions, here's what she suggested: "We used a 4" diameter tube with 3.5mm wall. We used a 5" diameter beam on the Tiki 36. You could use an oval section placed vertical, i.e. greatest depth up and down".<br></br>

For my t26, which is 2' narrower, I am using a 1/4" x 2 1/4" aluminum tube for the aft netting/ladder beam. This section is exceptionally stiff: I regularly sit in the middle of it and it shows no deflection. Here's a shot before I added teak plugs to the ends:<br/>

On the tikis, the forestay is bridled to u-bolts on the bows themselves. It would seem (best to ask Mr. Wharram's shop) that if you could keep the same geometry, the tiki method would solve the forebeam problem.</div>

Frank,<br />
<br />
Here is a shot of the location of the u-bolt location for the bridles on the tikis:<br />

<br />
It's almost halfway to the water, down the line of the bows.<br />
<br />
The main cleared the dodger by about 4" with the original mast. It's a low dodger, just enough room to sit under.
