I paid around $825 six years ago for a new one side Hobie Adventure Island alma outrigger with all the connection fittings. If you order through Hobie and plan to rig similar to mine, order the opposite aft extension so that the support angle piece goes under the trampoline instead of behind it where it will be in the way of the engine.
An alternative option is Expandacraft.

Keep checking Facebook market place and Offerup and maybe you will find a the parts used for much less.
Good luck.
