When you and your crew are under the minimum crew weight, what do you use for corrector weights? Where do you put the corrector weights?

This has never been a problem for me before, usually racing between 360# and 450#. My 9 year old is becoming useful and only weights 70#s.

Unless the class rules specify a location, I always put them either under or on the trampoline, right behind the mast.

Depends on how much weight you need to carry. 15# or less can be done with "beanbag" dive weights. Over that and you're probably talking barbell plates under the tramp.

noticed rhodysail attaching his to the rear tramp lacing (equal amount both sides, IIRC) and wondered why (if I did ask at the time, dont recall his reasoning)

It depends at little on the boat. In an ideal world you'd place them under the tramp near the mast (keep the weight central in minimise Pitching). However...... if your boat requires max weight aft down wind you might find them better at the back beam. You and your crew can always go fwd a bit upwind but its often rather hard to get any further back downwind without getting very wet and watchig your boat sail away.

Read your class rules.

Near the mast on most boats.

My boys moved their's front to back on the centre tramp lacing on the hobie 16 depending on wind strength.

Thanks all.

N20 Class rules:

7. CREW: Class legal minimums

7.1 Minimum Live Sailing Weight, Minimum Sailing Weight, corrector weight location and method of fixation;

7.1a Minimum Sailing Weight shall be the weight of the crew at registration, dressed in shorts / t-shirt or swim suit, and barefoot. Normal undergarments may also be worn with the aforementioned clothing.

1. The NACRA 20 Minimum Live Weight shall be 275lbs. consisting of a minimum of two (2) persons.

7.1b Minimum Sailing Weight shall be the Minimum Live Weight plus corrector weights if necessary.

1. The NACRA 20 Minimum Sailing Weight shall be 325lbs; however, for crews requiring more than 25lbs. plus 1/2 of the additional weight required need be carried.

7.1c Corrector Weights; corrector weights shall be attached to the outside of the main beam or within 1 foot aft of the main beam on or in the hulls or trampoline. Weights shall be curely attached to the boat and shall not be moved while racing. Attachment shall be with tape, or by tying with line led thru
the weights. Screws, rivets, nuts and bolts are not allowed. Weights must be easily accessible and easy to remove for check-weighing.
*********************************************

So, applying 7.1b.1 - me @205#, me boy @70# = 275# minimum live weight. Need to add corrector weight of 25#s and 1/2 of another 25#s, so total of 37.5#s; which put us at 312.5#s still under minimum weight of 325#s. Correct?

Yes, still under min weight but class legal per the rules.

You are racing a N20 with a 70lb crew! Not clever!

Not regular like, but in the right conditions. We have a lot of light air here on the Chesapeake. Last weekend I had boy, 9.875 yrs old and my daughter 7.5 yrs old as my crew, combined crew weight of about 320#s. Boy was on the wire almost the entire time. Wind was 5 to 10 from the south sometimes and sometimes not. We only had one gust that stood us up double trapped. Had the gust become the sustained wind we would have put the traveler down a few inches and called it a day. Probably would have gotten their Opti out for them. We ended up doing three or four races and would have done another but inbetween races my daughter encounted a jelly during her inbetween race swim . . . that ended our day.

Boy's jobs: trim jibe both upwind and down, trap, call laylines, waves and crossing situations. "Can we cross them? I say I say Boy, can we cross them..."

Daughters Jobs: Straighten lines, move her weight around without being told, especially forward, and looking for opposing boats. Especially, Flying Scots on Port coming downwind and not yielding to us. She will be yelling protest next time.

Chris, Chris, Chris, how naive!

You're new to daughters so let me PROMISE you that she will be yelling "PROTEST" until she's well out of her teens.

Don't ask me how I know. sick

Damn I'd need a 4 pound crew and people are adding weight!

I don't see that way.
First, rule 7.1b.1 needs to be revised some, but from what I'm reading, he should be carrying 75#.
Minimum Live Weight=MLW=275
Minimum Sailing Weight=MSW=325
Crews= (2) persons
(MSW=MLW+Corrector Weight) or(MSW-MLW=Corrector Weight)
(325-275)=50 (rule 7.1b)
n=corrector weight
n=50
if n>25 than (n+(nx1/2)=required corrector weight (rule 7.1b.1)
so . . . . . (50+(50x1/2)=75=required corrector weight

What's obvious is that 7.1b.1 needs to be rewritten. I'm absolutely positive that the class rules do not intend to reward and give advantage to a light team. The question is were the rules intended to "impart fairness" for extremely light teams by making them carry additional weight? If that were indeed the intent, it would make more since to change the Minimum Sailing Weight to 350#. That might make alot of sense for the N20 class, IMO!

Chris's above should read:
"So, applying 7.1b.1 - me @205#, me boy @70# = 275# minimum live weight. Need to add corrector weight of 25#s(50#s) and 1/2 of another 25#s(50#s), so total of 37.5#s(75#'s); which put us at 312.5#s(350#s)"

WRONG.

Correctors for "light crew" in clases that have it usually get you to carry 1/2 or some such formula as the weight being added is dead wight that cannot be moved around.

If you make lightweights carry all the weight (or more) to make them up to Min weight, they are then at a disadvantage to those that hit min weight exactly.

Hence whey under weigth crews carry some of the weight to get them back to min weight.

. . and could be argued that they are at an advantage to those who do not hit min weight exactly(that are heavy), light air, displacement, etc.

O.K. Overall, makes sense now. I didn't intend to imply they should carry more than #325, and I do not favor that. I'm really trying to get a better understanding of the "intent" of these type rules. Now when I go back and read 7.1b.1 I can see it from another perspective. It's funny when you race at well over 400# how prejudice takes place. I'm not sure I buy into the theory that less than #325 is always a disadvantage. Just curious, does F18 do this?

F18 does it in a similir way I think; "under weight" teams carry 1/2 the difference in weight (or something like that not 100% sure).

What ever cat people say, most efficient weight to be is usually in 140-160 kg as the sails can be flattened but you still have a lot of righting moment compared with 1/2 boats.

Boy reminded me yesterday as we were on our way to the club what he started singing every time the hull came out with him on the wire last week, well after the first time we were stood up: "Ohhh holy crap..."
