Stylish photo shoot, Louis! You're really helping to spread the "Haka Envy" movement.

I can tell you that, when you are sailing, you'll be moving around more on the boards for sure, so the lack of padding won't be so painfully obvious. Butt, cushions will help...

The paddle works quite well bungied or clipped to the outside Aka arm, (next to the bench). If you install locking clips or straps, you'll find that it can serve as a nice grab rail while you're hiking out.

Over time you may find it useful to screw, bolt or weld on "attachments" of your choosing.

Cupholders, anyone? :mrgreen:


I like mods that look OEM even if they require extra work, however it is hard to beat the KISS principle of engeneering when things fit as is. Here is my $12.00 cusion solution (Could not find Yellow locally, will upgrade to yellow when I find them). Added grommets to straps for bungie conection points Image
The stitching on the straps are spaced exactly the width of the haka so the fit is snug and doesn"t slip off the haka, however slides fore and aft with firm pressure. the amount of force needed to slide the cushions fore and aft can be adjusted by tightening or loosening the bungies.
Image

Image
In addition to saving my assets (still a little sore today), I now have more than enough throwables on board if needed.

PS does any one know if (2) 200lb crew could sit on the haka at the same time without damaging the akas? Now that this is a real possability want to hear if anyone else has tried and what the results were.

Stringy - thanks for that quick update!

Lou - I'm sure they could, so long as they aren't sitting on each others laps.

That would be pushing the envelope - and just plain wrong,..

The product description seems to be a mismatch for the photo

Hello from Barcelona!!

Yes, my Aka Bench is rotomolded and it sustain me perfectly just in the middle of it. No problem with that!!

6,1 kg (13,4lb) each one and with a weight capacity of up to 550lbs.

I use a rubber foam piece in front and rubber foam tubes rear. And secure them simply with a bungee. Fast and easy!!
I can use spineboard bench simultaneously with hobie tramps.

Louis. With my SUP boards on I have had two people on the wind side holding down the ama and we had a very good time. I havent tried with my wood set yet.

mbg,
Thanks for those details. They look ideal and would be maintenance free! 8)
Are they hollow or foam filled and do you have a link to a website that might have a bit more technical info?

How about 6.6 lbs Haka weight (12" wide x 66" long x 1" high. The extruded tubing is from 8020.net http://www.8020.net/9005-Pop-Up.htm. It features a 1/2" lip to mount the 6 mm Alumalite panel that is set 1/4" below the surface. This would make the panel flush with the top of the frame. The attached drawings assume TIG welded corners. NOTE: The tubing comes anodized. A small section of each end will need to be sanded at the weld zone to ensure a proper weld. 8020 offers plastic end connectors that I do not recommend. They are fine if you are building a door for a machine guard, but not to sit on. Properly welded corners will ensure a water tight connection thus preventing saltwater intrusion into the inside of the tubing. The red sections are drilled and tapped plates that are welded to the tubing to attach brackets, coolers, seat cushions, etc.
I think we may have found the lightest bench!!! Any thoughts???

Looks very light and not too expensive, how much do you estimate the materials and fabrication will cost for the aluminum frame?

Remember you will probably have to run the flutes on the alumilite across the width not the length since there are no horizontal members to stiffen the top panel. This will create (1) seam per Haka to deal with so you do not create a pinch point. Could just cover with nonslip tape.

So the flutes run only in the 48" direction? Good point. My supplier gave me a quote of $0.11 per inch for the aluminum extrusion 9005 but the cost of a 4'x 8' panel of Alumalite and Alucabest was $318.81 & $ 206.21!!!!

78" 80/20 9005 1" SQUARE SINGLE FLANGED QUICK FRAME $0.11 $8.78
80/20 2636 ALUCABEST 4' X 8' SHEET $317.81
80/20 2636 6MM YELLOW ALUM 4' X 8' SHEET $206.21

FROM SKARDA EQUIPMENT

The flutes run the 96" direction, however you should run them the shortest distance between supports to reduce flex.

See if a product called Alumicor is available in your area http://www.grimco.com/Products.aspx?cid=0988&pid=00402

It might be cheaper and serve the same purpose.

How much are you being charged to have the welding done or is it included in the per foot cost?

The price is for the tubing only. I have access to a machine shop & welding equipment in our manufacturing plant after hours. The tubing can be cut at a 45 degree angle with a miter saw. Most machine shops have welding equipment needed to weld aluminum. The key is to set the welder settings to not burn through the aluminum. A gusset plate in each corner would also help the rigidity of the structure also.
