Yours is an unusual request Creekdweller. Most people want more sail!
As FE Bob says your simplest option would be to fit an AI mast/sail in the TI. At around 2 foot shorter it should be more manageable.
This post discusses the differences in masts between AI, AIv2 and TI:
https://www.hobie.com/forums/viewtopic. ... 2&p=272771I fitted a TI mast to my old AI with no problems but to fit the AI mast to a TI you would have to remove and replace the furler drum and relocate it to fit. This wouldn't be too big a job for your Hobie dealer to do, with careful use of a dremel or the like. Many early AI masts had trouble with the drum slipping. It is epoxied on and is available as a spare part.
I have cut and pasted below from the linked post so you get some idea of what would be involved:
For reference this is a pic of AIv1 mast (top) alongside a TI mast (bottom). The difference in furler drums is clear.
Compare that to Chekika's pic comparing AIv1 (top) to AIv2 (bottom). It looks like the AI2 is using the TI furler drum?
