Its basically a few percent hit for sailing single handedly.

That is the L4 seen on this page. Modifications The default handicap numbers are listed HERE | | | Re: H16 or 18

(Its the first number in the column.) The other columns are for ratings in different wind ranges designated by the beufort scale. where 0-1 is no wind... drifter. B2-3 is about 11 knots and under B4 is 12 to 18 knots. When you register.. Sandy Hook has scoring program that computes your rating... Now... if you and your buddy... take the 16 out and you weigh in at 380 lbs... you get to use a slower rating by using the H correction factors. all of this is found here http://www.ussailing.org/portsmouth/pyindex.htmAs much as Mary would like to resist the notion.. weight on a boat matters ... So... the only question is... how do you want to handle the issue. Correct the elapsed times of the sailors... Add weight to all boats so that the total weigh of boat and crews are the same. Ignore the issue. get a different boat. get a different sail shape for the boat get different size sails for the boat After all.. racing is about the skill of the sailors.. right?

Your weight does not matter here... you are sailing a 2 man boat singlhanded. So.. you take the L4 correction.
Its not a penalty... it is a correction for your choosing to sail without a crew. Obviously, the boat is faster with just you on it... (providing you are able to keep the pointy end up). Since the boat is faster.. your rating has to get faster... so the rating number gets smaller.
Think of it this way... If you had a stiff boat with excellent sails and you sailed the perfect race.... you would sail the boat to its rating.... In the race against your buddy who is also singlhanded on the same kind of boat...in the case where you beat him across the line... he did not sail to his rating.... Several reasons could be the reason. he screwed up... he does not sails as well as you or his sails and boat were not up to speed. Now, when you race against a 16 sailing with two people. The handicaps are used to figure out who sailed better. The team sailing closer to their rating will win.

I dont know what the class weights for either the 16 or 18 is,but I weigh 200lbs.I guess what I am trying to figure out which boat will be better under the rating. I can sail either one equally as good. Class minimum crew weight for both the H16 and TheMightyHobie18 is 285 pounds. Find the class rules here 2005-2008 IHCA Class Rules Your being equally as good on either boat, and myself having having raced both, IMO race the 18. You'll be able to depower by furling the jib.

The 16 is only faster singlehanded in a very narrow range of conditions (i.e. up to maybe 8-10 knots). You just need 120-130 kg to get it going in anything over 10 knots. I would go for a 18 with wings, so you can get your weight way out. | | | Re: H16 or 18

Everybody knows that weight matters. I just didn't know what "L4" referred to (I thought maybe it was a typo), because I had never noticed that the modifications had little codes associated with them, and I have never seen a code used before in referring to a mod. factor. | | | Re: H16 or 18

Posts: 34 | bugger I thought I was the faster one than everybody. Heatbreaking to find out it's you. Easy choice, pick the boat you think will serve you best given the race, water and predicted weather. The ratings are not what matters. Your connection to the boat and your heart are what counts. When you think of the race what boat comes first into your image? You know thats a good point and sounds like there is alot to learn about the rules etc. I think I will just go and charge and do my bestand figure out the rules later I equally love both of them , but find I use the 18 a little more unless the surf is hairball then I use the 16.I would like to use the 18 but unless i can come up with a way to right it I think i will use the 16.Sorry about being faster. cheers-thomas <img src="http://www.catsailor.com/forums/images/graemlins/grin.gif" alt="" /> | | |
