Yes, vented to remove moisture and prevent mold growth.

You can see the louvered vent in the compartment door in the 4th picture in the first post

Do you have any plans or thoughts about ventilation for the fuel tank compartment?
I’m almost ready seal mine up ….unless I take the steps to create a ventilation path.
Your thoughts?

They seem to have a new 2021 version online of the boatbuilders handbook. You will probably find all USCG requirements from the following page.
https://safeafloat.com/boat-builders-handbook/

But...
As I told earlier. I have no clue witch laws you are required to follow. Spesifically I do not know if these apply to you as a homebuilder or only for those that build boats for sale.

But... there seems to be 13 instructional booklets about the requirements.  There are also some videos about how this test is done...

I have written on this topic earlier...
https://www.fishyfish.com/boards/general-discussion-tolman-skiffs/insulation-and-flatation/


For a Tollman boat the question if the boat will pass the stability test is to my knowledge unknown. If there are issues it probably has to do with the question if and how the boat floats. To make sure a boat below 20 feet floats correctly you need to place proper amounts of flotation material to counter stuff thats installed on your boat.  many on this forum install pool noodles in the bottom. The problem with this is that it will not ensure the boat floats evenly, so I think additional flotation material should be added along the sides of the boat below gunnels.  If your boat is above 20 feet the stability criteria for your boat is probably determined in a different way. It migth be that no test is needed but you need to present some table about positive righting moment to a specified degree or some calculations to demontrate that the boat characteristics are good enough. For bigger boats and ships stability requirements are commonly determined by moving predetermined weigths on deck and measuring how much the inclination changes. So its a calculation based on these angles. Another test determines the stability characteristics by measuring rolling times. I will study the new USCG reg as soon as I have time for it.  So this is just guessing. I have read the 2003 handbook, not the 2021 version.

I have no clue about the inner workings of USA legislation, but what i read in these posts sounds pretty similar to whats happened in EU with compliance to EU directive. To me it sounds like americans are starting to change their legislation to have it unified with ours.  If that is the case, my guess is that soon similar demands will appear in other states also. Could your state be the first of many states....?
Ofcourse I could simply be wrong and its just a mistake or...

Stability means different things for different sized boats, and depends also on how the boat is powered. Also intended use affects requirements (work boat, pleasure boat, inland waters, coastal area, open water... etc)  Smaller boats need to either "simply float" or "float in a level position" when completely filled with water. Larger boats usually dont have floating requirements, but there are other requirements for windows, everything that goes thru hull, roof strength, how high the cabin door is from the deck.... how fast water sheds off your boat in case a wave runs over your boat (for ex. in a bar crossing)...  even larger boats have requirements about bulkheads, watertight compartments... Ships have to be able to float even if they take some damage... One part of the stability assesment is determination of max load your boat can handle... 

In case you are really required to comply with USCG regulation find out the details. 

I have read the USCG stability documents some time ago, they are detailed and very informative. Find out if its only the stability test or does other parts of USCG regulation apply to you also. Also find out if you can "selfcertify". In EU there is a separate procedure for self certification. That is. I just need to make sure that my boat fulfills the requirements an put it on paper. That is can I can also do the the stability test. It just need to be on paper.

I know that European legislation was made in such a way (in co-operation with americans) that the demands were codified in about 70 standards. ABYC and USCG rules were part of the international process to make these standards. So it makes sence if they are starting to enforce the rules in US also.

Legislation here only makes it compulsory to have the boats CE sertified in order to sell it. Legislation only states that boats have to be safe, but what that means is codified in those standards in case of legal disputes. US and EU have declared to each other already some time ago that the requirements are compatible. 
===>
So probably after a while american boats built according to these standards can be sold in EU without extra inspections.  Probably also EU boats can be sold in US directly. 

Eu directive has a few exceptions. You cannot sell your home built boat (for 5 years) unless you have it certified safe and marked with CE plate. I guess the idea is that if you have managed to keep the boat afloat and use it for 5 years and someone is stupid enough to buy it, the boat must be safe enough to be sold. Historical boats or boats with steam engines... are also excluded.

Before doing anything else make sure You have the rigth information.

If needed
1. Read the USCG instructions for your boat
2. Find out what the requirements are for the stability test for your boat
3. Find out who can perform and how the stability tests are done.

Fuel tank shipped today, big thanks to KSH Fuel Products for fabbing up this custom design in short order. Maybe we can splash before year end?

My Bilge Pilates class continues to get ready for the tank install, some minor glass work and support for the new oil tank.

We may test start the replacement motor in the next few days also.

You're moving right along! The great thing about an aluminum tank, no gas stink!

Boat Electrical / Re: Charging batteries

I don’t know the answer, but I am learning a lot on YouTube from “Ask PYS”
It’s a channel run by an electrical engineer who specializes in boats.  He works out of Vancouver BC.  He sure knows his stuff.  I would bet he has already published an answer to your question.

Boat Electrical / Charging batteries
« Last post by Djeffrey on September 28, 2021, 06:19:42 PM »
I have a two battery system. One house battery and one starter, separated by a blue seas battery combiner. I have a xantrex charger and a xantrex monitor. If my battery’s get run down and I charge them by running the boat I get a 100% charge but if I plug the boat in at home I am not getting a full charge. Any ideas as to why? I am baffled

Looks fantastic!  Were the sandbags in photo one to make up for the missing motor and reduce trailer tongue weight?
Absolutely correct!
