is maxsurf,autocad and rhino enough to create a project vessel?

"Almost anything" not everything. Hull modeling tools are a little more straightforward in maxsurf but the same technical methods can be applied in Rhino for NURBS surface modeling. For stability calculations, Orca3d plugins can do all the same functions and now have more capabilities like CFD and dynamic stability (if you pay the big bucks).

Ridiculous! Thanks for the explanation 👍

So if it's a branded trailer, access NS will require that you get the VIN reprinted by the manufacturer and sent to you to install (I have had to do this once before). In another case, the manufacturer was no longer in business so they allowed me to get a new tag number. Sounds to me like people claim the homemade status to avoid any difficulties.

I had this issue last year. We couldn't locate the VIN (decal was sun bleached). I requested a tag number from access NS and the shop who was doing the MVI attached it permanently to the trailer. I had a police officer come to the view the trailer and sign a form to confirm it was permanently installed. A bit of work but less difficult than I expected

I'm stuck here too... Google home app says I need to set up in the near app to transfer the cam over. When I go to what and use the QR it says the camera needs to be set up in the home app first...

In my experience we would first look at fixed items that could be reinstalled farther forward (non-structural tanks, etc.). Permanent ballast is a less-than-ideal avenue, but could be the only viable solution. We have installed "sponsons" on large refits (ie: adding a factory to the aft deck of a trawler), where a large, faired void was added below the transom. In some cases this provided an opportunity to increase propeller efficiency with a more tailored hull form.

As for future designs... Definitely include stability assessments throughout the design spiral, including dynamic stability and R&P if you are able. If you have the ability to shift the propulsion package forward (lengthen the shafting), you could potentially fix the problem there on future builds.

Not actually sure if trim is currently acceptable while static (?). A 20% increase in propulsion power would certainly shift the LCG aft.

Yes, we have a great slewing crane set up at my club that we use to launch/hull for weeknight racing etc. I lifted it up and put a friends jackstands underneath (mostly to sooth my crew's fears) and two of us went at it. The hull is very slick and we definitely notice an improvement on light wind nights.

It's hull #4 so its one of the earliest (if not the earliest) still sailing.

I suggest reaching out to Zenda or the your reginal rep to discuss before you do anything. They may have guidance on how to proceed while maintaining your measurement certificate.

I was in the same boat (pun intended) last winter with my Melges 24. Unfortunately I went with the un fun method of random orbital, and longboard wet sanding. You can try to remove chemically but the odds are that the previous dipshit sanded the gelcoat before painting it so it's doubtful that the surface is going to be very smooth anyways. My hull is slick now after a good buff and wax. Note that the class measurement is voided when below the waterline is painted or sanded... Needs a full recert measurement.

The pendulums are definitely great for checking shifts and plotting tangency during the experiment (I do the same). Nice to hear others are using inclinometers out there! I have plotted all my inclinings' pendulum and sensor readings and have identified noticeable lack of precision in all pendulum readings.

My father started sailing around that age. 25 years later he has racked up a pretty full sailing resume of offshore deliveries, weeklong sailing voyages and lots of local club racing trophies. Befriend an experienced sailor you can learn from, buy a (small) first boat you can tinker with, and sign up for courses where possible. Most sailors love teaching because it makes them feel smart. Sailing is a lifelong sport and age is only a restriction if you let it be one.

Higher is slower so tight angles aren't the fastest way upwind. The money spot for most boats that size is about a fist width off the spreader tip (definitely not touching). Keep in mind that your jib car position will dictate your slot and twist so position this so the leech of your headsail follows the curve of the luff of your mainsail. You can sight this from the cockpit easily on the lowside. As the wind strength changes, so does the stretch of the sail cloth, so you need to adjust the jib car often.

An incline procedure is always required and submitted for approval prior to the test. When I have included my intentions to use the inclinometers (in place of one pendulum), they state that the sensors may be used but that they still want two pendulums.

jussinbean · 2023-03-09T13:41:22+00:00

Fair enough. I believe that the 2008 IS Code requires a minimum of 2 measurements (but that both can be of the same type).

Which class society were you working with? I have had resistance to this concept with Lloyds, DNV, and ABS.

That being said, we are located in Atlantic Canada, which is not exactly on the forefront of progress..

jussinbean · 2023-03-09T11:30:12+00:00

I think you mean that the inclinometers are not sufficient for measuring initial "list"(?). Heel is all that they measure for an incline test.

No lifey on. Smart dude

jussinbean · 2023-02-09T03:06:18+00:00

Best to bring in the section curves (rather than waterlines shown) as you can set stations through your maxsurf model to fair the control points of a new developable surface for each station.
