This boat wasn't fitted with batteries but had compensation weights. The outboard was also just a prop sealed with foam to avoid any oil contamination if it did go under water. This is also why we didn't want to have batteries on board (didn't want battery acid going into the sea). The fuel tank was also full of water approximately 200L.
Ok one thing I don't understand.. It might be unsinkable just by filling it up with à few buckets of water out in the calm bay. The most likely scenario in which this circumstance may actually happen is if someone has left the bungs out, the hull has been compromised by failure or potentially by protrusion of an object or hitting rocks, however this is all being displayed at a standstil situation??.. In reality, most rescues are from being capsized, in which too capsizing will most likely occur being washed up on the rocks.. If it could fuĺly up right itself after being capsized, that would be impressive
You have raised really great points, you are correct most sinking are due to the reasons you have described. In this video we have set out to prove our level floatation approval document that was done by a naval architect many years ago. We aren't claiming that the boat is self righting or that it can't be capsized or sunk, we are showing that it would be more difficult to capsize or sink a boat of this design than boats without this level of positive buoyancy. Doing this test in very rough waters could indeed lead to capsize, but again this type of boat won't sink fully with only tip of bow sticking out of water like many designs would. Also Coastguard would not approve of a test in 30 knot winds & 3 m swells. We do pride ourselves on the way our boats handle rough conditions.and there are lots of videos on RUclips demonstrating this. cheers.
@senatorboatsnz Thank you for your detailed response. As we all know, most potential buyers will search every review prior to purchasing... Responding like this will most certainly win over more potential buyers .. It was a great display of stability in those conditions and circumstances. Nice work 👍
I think i have seen 5+ boat makes of similar design , at least 3 from NZ , 1 chinese gospel i guess was a copy of stabi, and few in eastern Europe somewhat similar but not identical. Who come up with this design first ? Was it stabicraft ?
We have been around since 1996 and have developed our chamber boat design completely independently and very differently to Stabicraft. You will note that our hardtop boats have fully sealed chambers to the top of the gunwhales and variable deadrise hull design. We were the first chamber boat maker to follow this design path.
@@senatorboatsnz good to know. Never heard of this brand before. Would be good if you done a more detailed video on its construction. Maybe how air chambers look etc. we need more of boats like this in australia. At the moment they are relatively expensive compared to other brands . Maybe you could open a workshop here to make them more affordable
@@adventurehungry not sure which part of Australia you are from but we do have dealers in Western Australia, South Australia, Victoria and now also New South Wales. Feel free to check out the location details on our website here: www.senatorboats.com/contact/
No fishing gear, no anchors chain ropes, no electronics, batteries, windlass, no fuel, no water (fresh) and was that a complete engine or just the skin? Just saying don't get unhinged, also the 6 crew weren't All Blacks. That said it probably would float but in a decent blow and a couple of meter waves she'd probably turn turtle. at least it making a good attempt unlike a Kiwi made boat a while back that got pulled from a boat show because of a lack of buoyancy
@Antipodean33 Thanks for your comments. We are an honest bunch so wouldn’t pull any tricks to deceive anyone. I can assure you that we did go out of our way to make to replicate the fully loaded theoretical flood test that was calculated by a marine architect & ship surveyor many years ago. On the day of the test the boat was: 👉Fully fitted with full anchor, chain, rope and windless 👉Fuel tank fully full of water (190L), water was used instead of fuel for environmental reasons. 👉Outboard is an old 175hp that we got from one of our dealers, it is fully intact, but drained of oil and cowling sealed, again for environmental reasons. 👉Regarding the Crew - unfortunately not All Blacks, but average weight was probably around 85kg, a couple of big units on board, but we also had some lighter folk with us, plus we had a dog😊(we didn’t want to ask the weight of the lady on board…) 👉 No fishing gear, but we did also have 90+kg of compensation weights on board (to allow for batteries etc) and this boat also has and extended rail cage and duckboard which adds much more weight than a standard 620. 👉 In this video we have set out to prove our level floatation approval document that was done by a naval architect many years ago.

Hi there this is not a copy of a Stabicraft video. Just to clarify further, in this video we have set out to prove our level floatation approval document that was done by a naval architect many years ago. It's a test to prove the positive buoyancy of the hull.
Great demo, very impressive boat
Did you remove the batteries for the test or did they stay in and if so did they still function, excellent floatation.
This boat wasn't fitted with batteries but had compensation weights. The outboard was also just a prop sealed with foam to avoid any oil contamination if it did go under water.

mate if you want a boat that self rights get a yacht with a decent keel or a life boat
Nice!!
Was the water pumped out by the bilge pump or by the coastguard?
Hi there it was pumped out using the coastguard pump.
I think i have seen 5+ boat makes of similar design , at least 3 from NZ , 1 chinese gospel i guess was a copy of stabi, and few in eastern Europe somewhat similar but not identical.

Copy of stabicraft video?
Yep 😂
stabicraft invented buoyancy tests??

Let Ollie make your videos. Because this video got very annoying. Bloody music
