Here are the results of my early reasrch regarding SP Section Splits for upcoming regattas. This list includes designs that I am aware of sailing in NA. I may have missed some, so please speak up!!! Several ULDB designs I feel are questionable in my opionion and this needs to be addressed.
Let's start hearing from everyone, ok.
Class 0
Azzura 310 B-32 Columbia 30 Sport Sailor Farr 36 OD Henderson 30 Hobie 33 KIWI 35 Melges 30 Melges 32-1 Melges 32-2 Moore 30 Thompson 30 Thompson 35 Thompson 850 Thompson 870
Class 1 BOAT Antrim 27 B-25 Backman 21 Beneteau 25 PLATU Blusail 24 Capri 235 Catalina Carrera 280 Carrera 290 Cork 1720 Dibley 23 Elliott 770 Hobie Magic 25 Hotfoot 20 Hotfoot 24 J 80 JS9000 Martin 24-3 Melges 24 Moore 30 Phuket Sports 8 Rocket 22 Rocket 22 (2004) Sierra 26 SR 21 SR 25 SR 27 Thompson 590 Thompson 650 Thompson 750 Thompson 830 Ultimate 20 Ultimate 24 Viper 640 Viper 830 Wabbit 24
Why don't you publish the spreadsheet you have with boat data - would be very helpful for this exercise!
I would think you would want 3 divisions ideally. In PHRF speak I would think up to 70, 71- 110, 111 and up in PHRF speak.
Some comments on boats in the list:
Viper 830 move to class 0 (PHRF rating 63 - on par with T870) B32 a sportsboat? Hobie 33 a SB? B25 not a SB (SA/D 25) Bendytoy25 not a SB Capri 235 not a SB J80 Not a SB (SA/D 27) SR21,25,27 SB??
Rating are just part of the equation, displ/LWL is a more telling feature of the similar sailing charatistics.
To have section splits you need competitors, if we can actually get 20 boats for 2 sections ot start that would be super, you would need 30 for 3 sections, where was the last time you saw 30 SP at a single event?
The discussion regarding what makes a sport boat is just starting... In today's world there really are two distinct types of SP. The eariler Displ type and the newer higher performance style. Your 23.5 does qualify in my opionion.
In using various ratios to help determine the Sboat reletivity index,,,methinks the ballast/disp ratio only gives 1/2 the story.--It'd be useful to relate the SailArea/disp(SAD) #'s just as much!!--basically a power/weight ratio in addition to a righting moment criteria.
.....CHOICE OF RULES....On these --weight sensitive boats......does ANY measurement rule take into account the actual sailing displacement,,and righting moment of a --sailing weight',with crew on???....... .........................I'm not a designer,,but imho,,these considerations would seem CRUCIAL in accomodating a wide range of boats---------otherwise,go KISS,,,and start with PHRF,,which would probably the easiest for event organizers to accomodate!
Gybeset is right about the Cork 1720. It is trailerable but it is high with the keel on. The total towing weight is easily handled by most SUVs or small trucks. It is not ramp launchable though, you must use a hoist.
I don't understand the need for making the rule exclude non ramp launchable designs. There are better ways to limiting the design chartaristics of these boats.
Making non-overlapping jibs & ass spins would make the designs sail simular in a wide range of conditions.
It is also my vote for the executive committe to vote on which designs fit within our rules. Mumm 30 out unless sailed w/ Ass spin as an example.
--I guess I'm too much of a dinghy-sailor/anarchist!!!---I like the idea of developing some of our own events where all we need is a launch ramp!!,,and that can also be a good selling point for event hosts ,too!! ........fixed keels just seem too 'yachtie' for me!--and just like the 'trailer-sailer' aspect of what the Sboat definition might be,,,as in too big for a dinghy,,too small for a yacht.
Totally agree, however there are barely enough Sp in NA to start trying to weed some of them out. All we need is good section breaks to develop good racing. We need big events as our drawing card to get the available SP to go to onlty seclected big regional events. As more sailors see how much fum we're having we will grow!
I agree with Just another sailor "there are barely enough Sp in NA to start trying to weed some of them out". But if you are going to start somewhere why the keel? Are we going to restrict this to retractable keels only? What about canting keels? The Cork1720 with its fixed keel draws less water than many of the other retractable keels out there. Where are you going to race, where there are only ramps? fresh water lakes? I would bet anywhere you are limited by a ramp you would be limited by water depth as well. This group is supposed to help boats not established in OD yet race competitively with other similar boats.
