General Discussion about the Great Alaskan / Re: rotopax in the boat
« on: November 16, 2020, 11:05:03 PM »
Never heard of someone using them on a boat, but I don't see why you couldn't. They're a very popular item in the off-road/overland community. They seem to hold up well to the abuse and harsh environments that those guys put them threw. Lots of good mounting options and modularity. Obviously the plastic shouldn't be an issue in salt water, but take care of the mounting hardware to prevent corrosion.

Edit: Did a Google Image search for Rotopax Boat. Came across a handful of microskiffs and jetskis that are using the system. Also, the mounting hardware look like it may be anodized aluminum, so corrosion shouldn't be to big of a concern.

Definitely do the Euro style. I plan to do the same but with out the slant if possible. Need the Swim platform for Scuba Diving/spear fishing.

Boat Building Tools / Re: SketchUp

I can only imagine. I downloaded a tail version of rhino and orca to play around with. It was way to complicated for me though. Yea, self supporting hobbies are a bit of a bitter sweet juggling act. We definitely appreciate everything you're doing though!

I don't think it requires much of a learning curve for the basics. I'm still struggling with curve surfaces. I make it work but it won't be perfect. Just some key things that really keep you on track. Learning command shortcuts for the key board and using a mouse is you're on a laptop. A mouse is a must in my opinion. Also copying items before certain modifications, sometimes back tracking mistakes is complicated, but having the original item makes starting over easy. Example; outline I outlined the hull, went to extrude the plywood to 3/4" and half way through ran into issues. I couldn't back track and had to start over. If I had copied the outline first It would have saved half the time. All the basics can be learned on Youtube. Not practical for everyone, but I have nothing but time to kill with my current job.

I thought this might be a useful tool worth mentioning for others that are in the long term planning stages as well. As a first time builder, going through the instructions is confusing sometimes. Building it out on SketchUp is helping me visualize and learn the things that I don't understand at first glance. It won't be perfect(I'm not a computer guru), but its close enough and they have a free online version.

Sounds great Brian. Nice to know I'm not losing my mind and just misread the thread. I thought I just wasn't smart enough to find the plans   :o . I have some minor welding experience, the aluminum brazing sounds like it'll be a fun experiment.

Boat Building Tools / Epoxy Mixing Cart

Please forgive me Brian. I was looking for the info about the Epoxy cart plans. It wouldn't pull up with the search function and I didn't see it in the manual. Can we sticky thread it here for everyone?

Awesome Bro! Huge Milestone. I'm still in the planning stages, can't wait to see your build come along.

11
Looking Good.

HUGE.  Must have been great having so much help.  I did mine solo and would have nice to have one more set of hands.  Congrats!
Thank you, it was a great feeling flipping it over. It's funny they all want to help during the big events. But when its time to glass or sand they all hide. Still glad to have there help.

A great man once said, "They always show up, once all the work is done." Grab a beer and enjoy that much needed vacation. Here's some motivation I did while the hull was still upside down. Forgive the lack of artistic skill.

Bottom looks amazing! Good luck with the flip today!

Aside from aesthetics, is there an advantage/purpose for the bulwark vs. no bulwark?

Great question!

 The most seaworthy version of the Great Alaskan and/or the Kodiak, have the bulwark and high coaming around the cockpit (running just past the f'w'd part of the dry well).  Why?  More degrees of heel before water can enter the boat.  Or, another way to look at it is that water must rise higher on the side of the hull before water can enter the boat.  Think of a boat adrift and fishing, rolling hard to one side due to steep swells, and then a bigger than average wave strikes the boat on the low side ...

  Since this boat is designed for camping and fishing, it is expected that it'll see a lot of slow operation and/or just plain being adrift out on the big water.  This is why the boat has flared sides that help it bob up and over waves as they approach from most any direction.  Bulwarks help keep waves and water off the forward 2/3rds of the hull, and the coaming around the cockpit guide any such water draining aft over the side or at least into the scupper-drained dry well.  The bulwark also makes it safer to walk along the sheer deck to get forward for whatever reason... anyone who's done this on a slippery boat in a steep and unpredictable chop will appreciate this.  If you don't prefer the bulwark, then you could instead put a minor toe rail along the outer edge of the sheer just by trimming your side panels 3/4" high or so when you perform that part of the build (fillet and round it, then glass right over it when you glass the sheer deck to the sides).

  The only real downside to the coaming and bulwark is the extra time (and a minor cost) that it takes to add them to the boat ... no big deal in the long run.  In any case, lots of trade-offs ... you have to think about what you want to use your boat for and in what conditions, then make your decisions.  Style and the 'look' of the boat is a big deal.  Having handrails f'w'd have to be fit inside the bulwark and can make the walking-room on the sheer deck slightly less etc.

Thanks Brian. That was a great explanation. I like the idea of it. Specially the extended version Grady300 made that keeps the same smooth sheer angle. They aren't popular on the gulf coast of Florida. Mostly just nice giant bow rails.

General Discussion about the Great Alaskan / Re: Shower sump discharge
« on: October 26, 2020, 04:02:29 AM »
Current and from the EPA site. https://www.epa.gov/vessels-marinas-and-ports/vessel-sewage-frequently-asked-questions

What are the sewage discharge regulations/requirements in the United States?

Section 312 of the Clean Water Act requires the use of operable, U.S. Coast Guard-certified marine sanitation devices (MSDs) onboard vessels that are equipped with installed toilets and operating on U.S. navigable waters.
Untreated sewage discharges are prohibited within three miles from shore.
In order to discharge within three miles, sewage must be treated using a U.S. Coast Guard-approved Type I or Type II MSD. Alternatively, sewage may be stored onboard in a holding tank (Type III MSD).
Treated and untreated sewage discharges are prohibited in:
Freshwater lakes, reservoirs and other freshwater impoundments whole inlets or outlets are such as to prevent the ingress or egress by vessel traffic.
Rivers not capable of navigation by interstate vessel traffic.
No-discharge zones (NDZs) (as applicable).
In these areas, sewage effluent generally must be retained onboard in a holding tank (Type III MSD). Operators of vessels equipped with flow-through MSDs (Type I or Type II) must secure the device to prevent overboard discharge.
Visit the No-Discharge Zones (NDZs) by State webpage for more information on the location and applicability of NDZs.

Can I discharge graywater from my vessel?

Graywater is regulated differently depending on the type of vessel and whether it is mixed with sewage effluent. Commercial and military vessels have graywater requirements under the National Pollutant Discharge Elimination Systems (NPDES) permitting regime and the Uniform National Discharge Standards, respectively. For recreational vessels, there are currently no federal rules in place regulating graywater.

For all vessels, when graywater and sewage are mixed, the resulting discharge must meet sewage effluent requirements.
