A rating change would be nice. Here in So Cal we have a rating of 102 and different allowances for such items as smaller headsails, 3 bladed fixed props and so on. I find that the boat sails to the 102 rating as long as there is 7kts of breeze anything under that and the boat just doesn't respond. I too hate watching J-29's and the such pass me in light air, but when the breeze picks up I love picking them off the course and still being able to make celebratory margaritas with the blender...

Steve,

GOod luck. "Should get" is the operative term with PHRF Chesapeake. I looked in to challenging my rating as we have a base rating of 96 in the Chesapeake for wing or fin, Mk I or Mk II. No WK credit, no reduction for a 140 vs a 155 max headsail. We do get a RF white sail credit of 6 sec/mile for a rating of 102. Did some research on ratings in other areas with predominately light air and found C-42s with ratings up to 132. Catalina 400s...

If the C42 really weighs this much, shouldn't we get a higher PHRF value? It would help in light air races.

In any uncalibrated hoist, our new boat, no liquids, no mast (but rigging stil onboard) was 23,000 lbs.

I had my boat weighed in March of last year at Windward in Marina Del Rey. The travel lift weighed it at 26,000 pounds. There were not any personal items on board. It had 1/2 tank of fuel/ I do not know how much water was on board.

Just had our Mark I, 3-cabin fin keel weighed for an endorsed IRC rating we need this year for racing. Empty boat (no sails, sheets, anchors, rodes, tools, utensils, clothes, or anything else loose except the cushions on the berths below). Certified scales showed 24,240 lbs. The only significant item added to the boat is the air conditioner which is 78 lbs. There was 8 gal of fuel in the tank, all other tanks were empty. I will be weighing the gear when we put it back on, but the empty...

We just launched after bottom painting and repairs. Our lift operator said she weighed about 25000 lbs. In the water she sits about 3 inches from the blue stripe.

Btw, I did take measurements of the fin keel depth and it sits exactly 80 inches from the waterline confirming the previous 6'8" someone reported.

Garry, When we lifted Wild Child in the fall the operator said she weighed 24,000 pounds. At the time, I thought I might have to put her on a weight reduction plan, but if your boat really weighs 16 ton, I can make a few more trips to the chandlery without worry. Everything is relative, I guess.

If your boot stripe is under the waterline that is a problem. I think I misread something. I will let you now what my 42 weighs after being out of the water for two months and relaunched in mid feb. The coastguard uses net tonnage from hull design alone, nada on anything in or on the boat. Gross tonnage is with eq other than personal eq. This is my understanding and as my wife frequently tells me ,I am wrong, soooooo. lets compare weights at the end of feb. I love these posts!!!!!

It's actually not above the waterline and typically sits about 2" below when dry.
I did use Windward so if you are using same, ask the driver what yours weighs.

Gary, I will have boat in sling to change prop in 2 weeks. What yard did you use? I can't believe the weight number and expect your water line would be above the boot stripe at that weight.

Gene and others,

Thanks for the replies. I know that the Travel Lift is suspect but even give or take a thousand, my weight is still high.
Any other feedback on what others are weighing in at?

Gary,

I would be very suspicious of the measurement device on the Travel Lift. Unless it is used for some financial billing purpose, and unless it is routinely calibrated, it is likely to be far from accurate. The ones I have seen appear to be some sort of pressure gauge, but I am not sure how they are hooked up. If they simply attempt to measure the pull on the slings then the apparent weight will depend on the geometry of the loading and the height that the...

Weight-based systems
Displacement Tonnage is the actual weight of the vessel and its contents. It is often used to rate naval vessels, since their weight is fairly constant and they are not subject to the kinds of port fees that are calculated on Register Tonnage. It is often expressed in long tons or in metric tons, and is calculated simply by multiplying the volume of the hull below the waterline (ie. the volume of water it is displacing) by the density of the water. (Note...

the definitione of displacement weight vs.weight is always funny as displacement is the weight of the water displaced by the vessel not the vessels weight.

I'm embarrassed to say, but I just hauled out for a quick bottom paint repair and I asked the Travel lift driver what 'ol Breezn weighed. I should know better but I went ahead anyway and he told me that she weighed 16 tons!!! WHAT!!

Well, after recovering from my collapse, I started to remove everything off the boat at which time my wife suggested that I might need that particular tool and that bottle of wine is really fine etc, etc.
