Waterspout procedures

Today we were presented with a waterspout which appeared out of nowhere. Came within 1 mile
What would you do?

Re: Waterspout procedures

Cool Pic!

I would try to take a couple of bearings on it and try to monitor the bearings. Steady bearing, as with a boat might indicate a collision course, so I would try to maneuver out of its way.

I would reduce sail and dog down hatches. Life jackets and tethers on. I think I'd send any dogs and children down below until it passed.

Re: Waterspout procedures

We have encountered 3 in the last few months. The last one about a week ago at anchor. The system was moving off so no need take measures. The one before that was towards the end of May. That one we diverted to avoid the system but was interesting to watch the elongated spout churning up the water like a whirling dervish. It wasn't a long diversion though. I do not remember exactly where the third one was just now but didn't need to do anything.

Re: Waterspout procedures

What would I do?... probably soil my shorts.

Forgive me, but I would like to try an experiment with @chef2sail 's pictures;






WOO-HOO! It works like PB used to!!

Re: Waterspout procedures

Turn 90 deg to direction the thing is traveling... Haul A$$ and pray it doesn't catch you.

Life jackets are a good idea... but if that picks up the boat your chances are slim to none and slim went to a different state.

Re: Waterspout procedures

I wouldn't dump sails until its quite close as those white floppy bits can help you get away.

But, yeah, if it was coming close, furl/drop, engine on.

Depending on your area they may not be all that strong, but I understand the Florida Straits/Bahamas they can be a bit nasty.

The one in the pics look small.

Re: Waterspout procedures

The upper eastern shore of the Chesapeake usually gets more than its fair share of waterspouts, so does the Bahamas, the northern Caribbean basin and South Florida.

Waterspouts when present usually follow erratically along with the predominant (but changing) wind flow direction of an approaching weather front.

With instant access to doppler radar 'apps' (MyRadar, etc.) and/or onboard radar, when you see one or its associated 'roll cloud' coming - turn on the app, etc., look for the smaller 'dark-red/purple' spot(s) on the app, look to see the general direction of movement ... and then head off at 90° (usually to port) with the 'rotor' coming straight AT you (go 90° to stb. when in the southern hemisphere).
In the Ches. where the predominant wind flow when waterspouts are active is usually from west or northwest ('sometimes' from the north/NE with a 'backdoor' front); I usually go SW or W to escape 'into, through and under'.
In the Caribbean basin where the predominant wind flow is easterlies - I go northeasterly; but, if the storm/front is coming from a NW'er or 'Norther', then I go west or southwest when 'dodging'.

Usually such waterspouts are associated with an advancing low 'roll-cloud' .. usually a quite low 'sausage-like' cloud stretching from horizon to horizon slowly 'rolling' towards you. If you see any 'twisting fingers' hanging down from such a roll cloud, plan your escape 'through and under' the roll cloud; but (in the northern hemisphere) at 90° usually turning to port and away from any visible 'twisting fingers' or small funnel dropping down. Usually you'll see a small 'knot of wind' disturbing the water surface long before any of these 'twisting fingers' reach the water surface ... so look for the disturbance ON the water somewhere underneath any ragged and turning 'dangling cloud-fingers'
If visibility is 'bad', or at night, turn on your smart-phone doppler radar app connected to a cell network and/or onboard radar, and look for 'thin spots' along the approaching 'front' or roll cloud for WHERE to pass 'through and under' .

Waterspouts are usually quite narrow (in diameter) and their wind (in-flow) usually isn't all that bad, although can be momentarily violent if/when you take a 'direct hit'.
With 'forewarning', a good practice would be in such unstable conditions (just observing an advancing 'roll cloud' is good enough for me) would be: to 'close up and lock' all ports, windows, companionway, and outside lockers - just in-case you made an error in your choice of an escape path direction.

Obviously, doused and tied down sails probably should be SOP, until you're 'under and through' the roll cloud - similar to what you'd do when caught out and expecting a seiche, a 'real' strong weather front / 'white squall' to pass. Even if you take a direct hit of a strong spout, the usual 'very worst' will be a momentary knock down, or shredded sails.
Just use your eyeballs, or doppler radar app or onboard radar; and if in doubt, go at 90° to port if one is approaching 'head on' (and hope to hell that there isn't another 'rotor' hidden behind the first one and then needing the ability of some instant 'broken field maneuvering').
IMO - Its easier and faster to go 'under and through' a roll cloud, than to run before one.

Waterspouts are really not a 'big deal' as they're usually quite small and you usually can easily maneuver close-by and away from a direct hit, ..... unless you get surprised because you didn't anticipate and 'read' the oncoming weather front.

for iPhones/iPads - MyRadar app: https://itunes.apple.com/us/app/myra...322439990?mt=8 ... this app also 'can' overlay wind direction and strength 'arrows'.

Re: Waterspout procedures

Was wild too see so close, however I was still in the marina... Ive encountered a small one a few years ago, turned Southeast and it went on by... if not a bit of excitement.

Re: Waterspout procedures

They do occasionally knock a boat or two off their jack stands deeper in at Worton Creek, (and/or a 'tree or two') when they hit the upper eastern shore ... but usually just one or two boats and not the whole damn lot.
