    Aft view shows rig with mahogany (orig plans called for white pine) hiking boards.

    Orig plans suggest to anchor boards to akas, which are metal, not wood, using only binding or lashing, surely to maintain rig flexibility, instead of fixing with fasteners to akas...

    Trouble is boards slide too much for comfort.

    Any ideas? I prefer not to drill into akas, but thinking on it.

    Also I have bamboo length to fasten to boards abeam to keep them apart.

    Never occurred to me...not a bad idea. Thanks.

    I sometimes use bike inner tubes for temporary fastening before going to 5200 etc... , you would want a stronger rubber but it makes a world of difference.

    You both gave me a nudge. What about hook and loop strips-with lashing?

    I also have some old bike inner tube material...interesting idea!

    yeah Hook and Loop might work too, don't know how long it will last though

    Thanks, your comment got me there. Had thought of sandpaper but figured too slippery. I have some unused hook and loop been laying around...why not? Merci!

    BTW, the mahogany hiking boards are 8-feet long x 10-inches wide x 1 inch thick...heavy; even with cut-outs and more why they tend to slid easily. Still, what the heck! rough hook/loop might do it.

    Mais oui! Of course I will report back...

    Just thought of it. Last year I "clear-coated" all the exposed AL with regular old Krylon and will have to remove before adhesive applied. Stuff seems to be "the" answer for shielding AL...FWIW.

    The hook and loop sounds like a nice idea. On my small outrigger I use inner tubes a lot to get more friction, and sometimes I use stainless steel hose clamps. You can make these clamps much tighter than lashings. Of course they don't look as good.
    Another thing that works well are "exhaust muffler clamps"? dont know the English words. They are U bolts with saddle used for exhaust pipes on cars. But your beams look very big diameter, so in this case probably not a good idea.
    Cheers, Hans

    Okay, will post pictures later...been raining here.

    I used some hook and loop strips...one inch wide...white...had tons on hand for sail luff to carbon spar set---works well there...never thought of it until above...I used the narrow strips as the akas are round and the contact surface is narrow due to radius...but seems to work.

    Anyway, mixed up some epoxy goo...the green West stuff on hand and cut the strips to length, roughed up AL and woods for grip surface, smeared on goo and set the strips in place on AL aka spots and the boards, let cure and then plopped in place on akas. They do not slide. Today will lash down (overkill?) to akas and take some pics and post. So far so good. Very tenacious stuff, if the goo does hold to wood and metal.

    I apologize...forgot to take pics and post. Will do in hour or so, when light is better.

    Duh on me!

    So far, boards are lashed down and the hook/loop material holds; but not sailed it that way yet.

    Pics will do better but not going to sail until Friday or Monday (I do not sail weekends to avoid crowds...)and will report again. I trust the hook and loop will work, as I use to hold sail and works so far, but gets dirty fast. Have little choice though. Big main...220.

    First rig I ever had that I rigged; all others were class used rigs. Got to say, rigging from beginning is a bit fun/tedious and time consuming. Seems all I do is fix errors. Hope using boards on metal akas was not one of them.

    planks2.jpg planks3.jpg I should have taken pics of strips on wood but did not think necessary. As you can see, I roughed up metal and did same to wood before applying the epoxy, set in place and lashed. Will have to tension the lashing better and add the bamboo cross piece in center.

    I plan to add the tramp below the boards later, but picking up replacement pre hung door later and did not want to deal with tramp...wind etc.

    If anyone has idea to knot tension the lashings share it by all means. I did not really tension the lashings so far...

    Thanks! I would like it more, if not spending so much time fixing my screw-ups...

    Did sail it last year, in some impatient haste, rig did fine...actually moves right along and had to change a couple things. Very simple rig.

    Added boards to be more like original Malibu Outrigger, but getting white pine or even plain Doug fir is impossible, so we did the mahogany and lightened them...will sail Monday next, sucker does not sink...thanks...does the job, so far.
