    More Modeling: High Resolution Bathymetry --> local Currents

    I can tell you a hydrodynamic model can be much more complex than what you are referencing. We typically run our models on our 48 core machine and a fully coupled model with including boundary inputs (tides, winds, waves) will take around a week or two to run for a 1 month duration model run. For your case that's on the order of what you should expect as the models typically need a ramp up time for the computation to stabilize. You'll also need to calibrate which can be tedious without a good source of flow and tide data. On the bathymetry, if you're running a general basin model, typically you won't need to worry about those kinds of structures as they're overall contribution to the circulation will be minor. If you really want to get that detailed with it then you would likely have to create an even finer smaller grid that you can force with the results from your larger basinwide model. Keep in mind these models are typically used to hindcast conditions and it's difficult to get them to a point where you can model conditions in real time without a supercomputer. And even then, you're model is only as good as the input data you provide it which sounds to be fairly limited for this case.

    More Modeling: High Resolution Bathymetry --> local Currents

    I happen to do this kind of modeling all the time for my work. You can use delft3d which is an open source hydrodynamic model that's used for that very purpose. With delft you can put together a mesh with varying resolution where you can have the cells as large as 200m in the offshore and then reduce down to about 2 to 5m. The final resolution will depend on the model you're using and the size of the grid. If you're resolution is not fine enough the model will crash, but if you refine your mesh too much the model will take forever to run. Typically for this type of model we end up using between 1 to 2m spacing at shallower areas. Keep in mind as Panoramix mentioned, this type of modeling is pretty intense and it takes a thorough understanding of coastal hydrodynamics and numerical modeling to get it working properly. You'll need to thoroughly research the model input conditions that you'll be using to get started. We can typically get this type of model going after about two solid weeks of work so if you're doing this as a hobby and learning things on the fly It could take you up to a year to get the model to accurately represent the conditions at the Estuary.

    Nobody Wants To Take Up Sailing

    As a younger (under 30) keelboat owner I'd say I agree with many of the points discussed here. It's hard for us millenials to afford the time and $ it takes to own a boat which then gets compounded it you want to race. I was only able to do it by finding a co-owner crazy enough to want to buy a boat and to help with the costs and maintenance part of owning the boat. Finding crew is usually not that hard, it's just tough to find the time to find crew, train them, and then keep them interested long enough to get them racing. But all of this is the normal stuff for owning the boat that I expected getting into it and to me is part of the fun. I think part of it is that there's still quite a few people running these yacht clubs with the elitist sailing mentality and outdated approach to handling the sport. Many don't want new people in their exclusive club and make it known to those newcomers through their attitudes on and off of the water. Then you get into bringing in new comers to the sport. I think YC's have the power to really grow the sport if they would target the right people. It seems to me that most YC's emphasize a lot on training the young kids to sail and to keep the older generations out on the water, but there's not much being done to get those younger professionals recently out of college whom haven't been exposed to sailing into the sport. Crewing on a race boat is great way to learn, but few skippers would allow such a person to drive their boat on any given day, or, at least, not enough to really get hooked on the sport. They could take a class, but those are few and far between in many places and cost quite a bit of $ especially for someone who isn't sure if they're going to like it or not. I think people need tiller time on a boat to really get hooked on the sport and I don't think many of us (especially us racers) are giving people that time.
