This one is easy.
Step 1 - Google search sailmakers near you
Step 2 - Go ask them these questions:
Your local sailmakers probably do a lot of business with local sailors. They also will know the cubs, classes, rules, etc. Their business depends on it. I've known my local Doyle dealer for 20 years. When I switched to a roller furler(a 3 second credit), I bought anew Man an #1 ad had my #2 and #3 recut. These people's livelihood depends on knowing the local racing community. Ring sailors spend money with e every season. Cruisers buy new sails every 10 years or so.
Step 3: Listen to them:
The good ones will not only make you the sails, they'll go with you the first few times you race and teach you how best to trim and treat your big new investment.
Now, take this for what it's worth. After more than 25 years racing with symmetrical spinnakers, I switched to Asyms.
Reason #1: Crew turnover is a fact of life. You may have the best bowman around who can handle the sheets, guys, pole, downhaul, and topping lift like a pro. I will guarantee he/she will: get married, have a kid, move, get a new job, get injured. Then, you're left with a complicated job and a newbie. Pain, screaming, and bad finishes are not far behind.
Reason #2: You really only need 3 spinnakers, tops. 1 AP(all Purpose), 1 Heavier Reacher(extreme luxury), and a Code 0. With symmetricals, you'll usually carry a .5oz, a .75oz, a 1.5 oz d, possibly a 2.2oz. If the rules allow, you'll also carry a staysail. Think $$$
Reason #3: Shorthanded crew is also a fact of life. With an Asym, you really only need 1 foredeck. And, they don't need to be as experienced.
Reason #4: Here, we received another 3 second credit for using an asym.
My experience with Hunters: Don't be offended but Hunters are not racing boats. PHRF clubs don't have ratings ready for them. That being said, the Hunters I race against have CRAZY high ratings. That means they're rated much slower than they are and we ow them a ton of time. If it's blowing over 12 Knts and most of the course is a reach or a run, they're tough to beat. If it's upwind, I'm home when they finish.
So, bottom line? Go to steps 1,2 and 3. You'll get what you need, and you'll probably spend less by not burying sails you don't need. You could even give them your budget for the whole set and they'd find a way to get you everything you need.
Good luck, and remember, always be on starboard
