I fitted a 35 square foot Bermuda sail with boom/kick strap/ furling ability from Solwày Dory in the UK to my ÀI in adventure mode ( no Amas)
Image
I used pvc pipe specers and PE sheet shims together with the Hobie Furler and mast foot to get the 38 mm mast to fit (a press fit with a rubber hammer), meaning I didn’t need to use any funky glues. The tube clip is just à backup...
Image

I thought it might be a bit too big as the mast is almost as heavy as the standard AI one, albeit shorter, but in combination with cut down Àkas with PU foam padding to help lean out...
Image

...and which fold in for docking...
Image

...it worked out really well in the 9/11 knot gusts I tried it in (with small wind waves) I find kickers a bit tricky when turning downwind and this in combination with the weird reverse steering linkages on the AI (why did they do this!?) had me in the drink early on before I got the hang of it, but after furling the sail, it was reàlly easy to right the kayak using the cut down Akas for leverage. After disconnecting the kicker I went on to have a blast balancing the main ànd the tiller against the wind and waves :-)

First adventure with a real boom, I believe.

Extra points earned for the padded armrests! :mrgreen:

Great work Simon. Cut down aka for hiking out also a first I believe. Very innovative. 8)
Did you have the daggerboard down when you capsized?

Thanks guys :-)

Daggerboard was down but I steered the wrong (right in any other boat) way initially in the first gust with the kicker connected to the Drive leash eye, whereupon the kicker tightened up and locked the sail and over I went. I was aware this might happen but thought I'd be able to loosen the kicker in time. Wrong... Beginner's mistake :-) The kicker is supposed to attach to the mast (or a furler drum hole) as recommended by Solway Dory, but that means having to disconnect it when furling.

After I disconnected the kicker I had a lot of fun in the gusts coming through a cut in the hills at 90 degrees to the small waves in the bay. I started with the rig partially furled but it didn't take long to get used to sailing it on what was only my my first time out ever in my AI and my first time sailing in donkey's years with anything other than a tiny Pacific action sail on a sea kayak.
Once I started leaning back and out on the cut down Aka's ( Ak's? :-)), I was pleasantly surprised by how stable and forgiving the sét up was for such a narrow boat with the sail fully unfurled. I think the weight must help. I did miss the kicker downwind a bit so will probably refit it next time out.

The set up's not perfect for me but once I fit some kind of hiking strap, an extra pulley for the main, tie the mast yoke on the boom to the mast and reverse the pull on the outhaul on the boom with a small pulley at the mast end, i think I'll be very happy with it indeed.

Shame it won't plane, mind :-)

Having sailed a fair bit before getting my TI, at first the "reverse tiller" confused me too, but it didn't take long to adapt to the standard Hobie layout.

If you are still sailing other boats as well, you might like to change the Hobie steering lines over so the tiller works conventionally.

The cut down Aka's worked much like training wheels: I removed them before my last outing along with the rear cross bar. This allowed me to lean back AND hike out more easily and lower, in combination with a hiking stick and a hiking out strap for my feet tied across the yak amd level with the front of the carry handles. A really good work out for my ageing abs :-) Being able to lean way back and low really helped with my Adventure's marked tendency to broach and.rock in solo mode downwind across following seas too

I fitted a better vang to a loose noose around the mast, a pulley to reverse the outhaul on the boom and secured the boom yoke to the mast with loosely fitting zip ties. The Adenture as rigged is so forgiving and as long as your reactions are reasonably quick you'd have to reaaaaally push it to get blown over, although I still find gybing a bit hairy. It does take a while to set up however so I can see the attraction of the simple boomless Hobie sails.

I had a blast yesterday hiking way out to stay with a TI upwind in 10 - 15 knot gusts, but I couldn't keep up with him on a broad reach. I also tied an inflated empty MSR ”Dromedary” water bag to the mast head as a float and tested it. It stopped the mast going under, making the yak fairly easy to right with straps but no outriggers

Balancing the boat against the wind constantly with body weight, the mainsheet and the tiller does mean the rudder lines take a beating and the main problem I've encountered is having to retighten the rudder lines between outings. I'm using half hitches under washers and a reef knot but they do slip, so if anyone has a better solution, could you please let me know?

It is sorta cool, but part of me asks the question "why disable the AI's excellent performance as a sailing trimaran?" Not only do you lose the stability, but probably more importantly, you lose the ability to easily reef the sail.

Just intrigued..

Hi Tony,
To answer your question
1. There's usually no wind at all or very little until around 2 where I am, so I usually peddle out= less work in a monohull - I may yet bend the akas up to keep the amas out of the water instead, but see 4.
2. From what I read the AI is slow in light airs anyway so I don't think I'm losing out much in he 10 to 15 knot max afternoon gusts we get here (often only 5 to 7)
3. I really enjoy the challenge of balancing a skinny hull agsinst the wind in the sail
4. I have very limited storage space (a kayak rack in a narrow corridor) at te marina where I keep it
5. The Solway Dory rig has a furling mast - you just have to uncleat the outhaul from the boom first

:-)

Once I get fitter and more skilled I'm really tempted to add a boom to the hobie rig and try it out in light airs as a monohull, especially as the wind can drop a lot here after the summer

Now about those better knots for the rudder lines.....
