Update Sailing with no AMA's:
I described a keel weight system on this thread so the TI can be sailed without the AMA's for those times when we are out on rivers just kayaking but also want to be able to sail (like we do with our regular kayaks ( ie.. revo, Oasis, etc), or we just want to go out for a quick sail and don't want to go through all the hassle of loading the AMA's and all the gear (kayak mode). Well I went ahead and made a weighted keel that mounts into the rear Mirage drive holder and it works great (see pics below). The first version was the 25 lb keel weight I made 3 yrs ago for my Oasis (still had it), I went out last week and tried it on my TI and it worked for the most part, I could sail in light winds with normal TI mainsail but it was a little shaky and I if the boat tilted past 50-55 degrees it would keep on going over (yes I went swimming). With 50 lbs I can stand on the rail and the boat doesn't tip over (see pic), This latest version is 50 lbs and keeps the boat from tipping even with the sail up in light conditions similar to a monohull (have not tried it in heavier wind conditions) I am only using the main 90 sq ft sail for this and am not even going to attempt flying 260 sq ft of sail. The weight is supported by two spectra lines tied to the AKA mounts so as not to stress the Mirage drive pocket. The way I figure it is this keel weight weighs the same as the AMA's but is alot smaller and easier to transport and rig (just plug it in). It took me about 5 minutes to launch the boat vs the normal 30 minutes.
This is me standing on the rail (notice I'm wet, it was attempt #2)
Here is the unit ready to drop in, I used lead shot (old scuba weight belt) embedded in polyester resin to for the weight.
I can still transport with the scupper cart.
