From the images I found it looks like it would be a good boat for a one-design (everyone sails exactly the same stock boat) class. I cannot tell from the pictures, but it looks like it does not have a jib boom topping lift which means that to adjust the twist of the jib to match that of the main you will need to be able to adjust the jib leech tension, This is a common issue with boats using flat panel saiils - that is sails constructed from single pieces of cloth. Multiple panel sails are constructed with a built in curve that better uses the force of the wind and paneled sails need a topping lift tp get their full effect. Seawinds, and most of the Asian boats, have the same issue in that they were made to look pretty, but do not have rigging built with adjusting the sails in mind.
To get a boat that sails well and will not frustrate beginners attempting to use tuning guides found on-line, I would strongly suggest that you new fleet consider allowing jib boom topping lifts. They are cheap and easy to add to most boats - most of the time you drill two holes and add a line with a bowsie.
It took me a better part of a year of racing and practice with a group of guys to get the hang of tuning a Seawind, where I could tune an Infinity 54 or US1M, both of which have topping lifts, within a few weeks. The use of jib topping lifts for the Seawind has been put to a class vote in the US, but keeps failing to pass IMHO because the experienced skippers do not want to give away their competive advantage based on their knowledge about how to tune the rig.
Anyway, take a look at the Seawind Resource Center website atwww.seawindrc.com
to see the Seawind US class rules that you might use as a model for your new class. There is also an article there about how a topping lift could be added. The topping lift article is here:www.seawindrc.com/tips-mods/jibtoppinglift.asp
I don't thing the Hurrican would even need the jib boom extension.
While you are doing some web surfing, the beginners in your fleet might find the following article of value when setting up their boats and tuning their rigs: c_r_y_a.tripod.com/Sterne%20How%20to.htm
While you cannot do all the things like the article suggests, like changing to different size sails when the wind blows harder, if you do the things you can do, your boat will be as fast as it can be made to be.
Good luck and welcome to the addiction!
