<p>I am quite sure the 6 " beam mentioned refers to the fwd beam . Steve's (fiberglass) versions of the T 26 had, if i am not mistaken, the same two main beams as the "normal" wood -hulled T26's. 6"dia alu pipe seems in any case awfully small for a beam whihc not only holds the hulls together but is subject to the loads induced by mast & rig as well.</p>

<p>We built a Hitia 26 ( T 26 without the cabins, it's used as a day sailer, learn-to sail boat and camping cruiser) with alu beams . Boat is two ft wider then a standard T26. beam nr 1 is an ordinary 6" 4mm wall alu pipe. Beams nr2 and 3 were made of a salvaged mast of a 38ft piver trimaran whihc was wrecked in our bay . We did not bother with the dolphin striker on the mast beam. I do not think there will be much diffrence in weight between a wooden main beam and an equally strong alu beam. The standard nr 1 beam as designed by JWD on a 26 can, as seen, be replaced by an alu pipe and this does save a considerable amount of weight </p> Of the varieties of aluminum,…tag:wharrambuilders.ning.com,2020-11-07:2195841:Comment:2086702020-11-07T17:30:37.338ZDean Wilkersonhttps://wharrambuilders.ning.com/profile/DeanWilkerson
<p>Of the varieties of aluminum, probably the best choice for this is 6061 T6. It is tough and forgiving, and fairly resistant to corrosion as well as to fatigue.</p>
<p></p>
<p>Personally I feel aluminum is about the worst possible choice for something of this nature. It is extremely reactive and subject to electrolysis and electrolytic corrosion. It also has a far shorter fatigue life than wood, so if there is any flexing and bending, it will eventually end up with fatigue cracking. …</p>

Wood, if you choose quality wood and build well is the most reliable of all materials structurally. Choosing the right wood, and using the right construction methods and protection, matters of course. My personal choice for this kind of application would be good quality knot free close grain Douglas Fir. </p>

<p>According to Aluminiumwarehouse.co.uk it's an industry name for 6082 T6. The 6082 refers to the chemical composition of the alloy, and the T6 refers to the heat treatment it is given to achieve the desired mechanical properties. It's quite a common alloy, I think it's the sort of material aluminium masts are made from. The following comes from their website:-</p>

Ahh thanks Johnny,<br />
What does the H30 stand for?<br />
I was also wondering rather than tube if an I beam might be better? would make a nicer area to paint non slip paint on and easier to bolt through any cleats etc..

<p>Sadly sold my Tiki 26 but had always thought you could make an open box beam with aluminium angle and ply - a new product I am using is "ply" made from recycled plastic - comes in standard 8x4 sheets and 19mm or 9mm.</p>
<p></p>
<p>So if you will homemade composite - use angle for edges and the plastic ply for sides - maybe rout out holes for weight reduction, and maybe some verticals in aluminium - a bit like you see on scaffolding sites.</p>

<p>I would be interested to know about the specifications for beams made out of aluminium tubing for the Tiki 21 or 26. It is interesting to see the Mana fitted with 2 square beams under each mast and no other beam. Obviously there is less compression on the mast beam without a jib. Their sections are about 6"x6" and 6"x12". Wharram has used glulam solid beam then I-beams then triangular beams before using square tubing. Any comments?

I am building a tiki 30 and really want to use aluminum beams also. Any information on this would be helpful.
