Jupiter Inlet Boat Sinking - Page 4

psneeld · 10-31-2017, 05:06 AM

Goes to show perspective. Both owners of the assistance towing company I work love the old Shamrocks. I am still running one after 15 years, but only part time now.

Have a fleet of 4 of them covering one of the companies largest franchises. One guy still has a shell of one on his lot, just in case.

My comment is always ...the shamrock is like a swiss army knife, not great at anything, but good at anything.

I will say the original owner did put 454s and oversized 4 bladed props on them. Slowed them down a bit, but man they could dig a boat out and pull like crazy..

operator error ?

On Facebook they said there was already a ton of water in her bilge and it moved up to the bow in that one wave.

Yup and hello free surface effect. The bow did dig in before going under.

Isn't there something about pumping the bilges before entering a harbor?

Does it say anything about the cause of a ton of water in her bilge?

There has been quite a bit of un-fun at the Sebastian Inlet also.

Five people rescued after two boats overturn in the Sebastian Inlet

A scenario where something like a Seabrake might have been useful, if deployed early enough:

Ben,
“Not finding yourself in that position”
Indeed one needs to climb up on the next wave far enough so the wave aft dosn’t threaten your boat attitude to the extent that you get pooped or (in this case) get your stern high up so your bow goes below the surface. One needs to look aft more than fwd. But most are wide eyed looking fwd so the wave comming up aft can have it’s way with you and your boat.

Big waves move faster than small waves. Gots to keep very aware of what is behind you. A big one can sneak up on you while you have the bow on a smaller one.

Greetings,
Mr. MM. Interesting unit that seabrake BUT I think IF this vessel was carrying that much water/load, such a device would keep the stern lower causing a poop condition particularly IF it was water in the bilge and the free surface effect, previously mentioned, took effect.

BandB · 10-31-2017, 11:08 AM

The Sebastian one isn't even in bad conditions. Just shows how even skilled boaters can make one small mistake and find themselves in that situation. Also, shows the risk of towing.

Kudos to FWC and others involved in the rescue.

Hmmmm, no prices posted in the URL.

Reported as a 26 stapleton, 9ft beam. But i’ve never heard of them.

Found a pic of the bow of one of those online...

Yea, I have basically the Shamrock 22 in that picture and that didn’t look like my boat to me.

The Shamrock does some odd things at times, but she has tremendous bow rise if you push the throttle a little, and that’s a tall bow. Good analogy with the Swiss Army knife, too.

Soon after getting my captains license in 1973 I ran a 55' steel crew boat with a pair of Detroit Diesel 12V 71 engines in and out of that same inlet for two summers. I was taking crew to a dredge off the beach for beach re-nourishment, four trips a day, so 8 trips through Jupiter Inlet each day.
The Atlantic Coast pilot then stated that it was not a navigable inlet and there was a big sign post on the ICW warning not to use the inlet. I knew where the shoals were and where the waves would build, but if there was any kind of a big swell I would go south to the Lake Worth (Palm Beach) Inlet. That added a lot of time to the trip but I always has passengers and never wanted to take a chance. The dredge guys would complain about the extra time but none ever had to swim to the beach.

That Stapelton bow does not have any reserve buoyancy, not enough volume. By the time that wide flare touches the water, it is already too late.
The bow volume may have been a factor too.

Hi RT,

My thinking was that if he'd used something like a Seabrake earlier, once things started getting gnarly, he might not have shipped so much water before entering the area where he sank. The device appears to allow controlled forward progress downwind in following seas without broaching, and if set up properly, I don't think it would hold the stern too low either.

psneeld · 10-31-2017, 04:12 PM

I see the seabrake very useful in open water seas or large long period swells breaking in an inlet.

The short steep chop like in the video and what I am used to in eastern US breaking inlets under most conditions, I would not use any sort of drogue. I might/would on a boat I was towing though.

Unless I missed something, in the video, the wave crest separation wasnt much longer than the boat length.

TheDroneGuy · 11-03-2017, 11:33 PM

Just letting you know that I took the video...

Saying I've been busy since the video got Out There is an understatement

I have no idea when I can make it back here to answer any questions so I'll tell you some things now...

There's a LOT of conjecture and misinformation all over the place...
No I do not go there to Fly just when it's rough...
I actually went there that day an hour before High Tide wanting to get video of Awesome Blue Water (plus boats like attached pictures) but the water wasn't clear/blue so yes I did stay until the tide was running out (with 20+mph wind coming in from east)...

Drone Cameras don't record sound so only the people close by (like me) could hear the engine...
I heard him working the throttle trying his best not to let this happen = he was Off-Throttle before he got pushed into the wave.
The waves were very Fluid (no pun intended) = Wave Frequency (distance) vs Boat Length and Shape were "constantly changing"...
After watching the Full Size HD video Several Times (wave frequency and morphing) IMO Lady Luck wasn't with him at that exact moment...
The man has been doing this for over 30 years so any statements that he had no idea what he was doing are unfounded...

Everything is much sharper and larger on the Full Size HD video which I'll be posting on my YouTube ASAP, but just like not knowing when I can come back here to reply, I can't say when the video will be edited and up

I will do my best to share it here but if you want to be notified when it's up you should go to my YouTube Channel https://www.youtube.com/channel/UCCZ...PKxwoU1aPnuijg and Subscribe (click on little bell at upper right after subscribing to get noitified)...
