Hi Piers, I’m asking this question on behalf of my friend Roger who has a Princess 50. He remembers you and said you showed him around Play d’eau in the Portsmouth area. He’s asking how you are and where abouts are you?

Would need to be a hell of a megaphone to reach southern Italy :p

Anyway, if you only take the log out and clean it, it will gunk up again pretty quickly. Antifouling it after cleaning (there is special stuff available, don't know if it's essential) will delay the process.

I don't have a motorboat, but if I did I don't think I'd bother with a paddlewheel log. Even on my sailing boat I use it little enough nowadays, to be honest.

I honestly can’t remember the last time I used my paddle wheel log. With 2 separate gps units, plus the phone and iPad running Navionics, I can’t see the need to use it.

But to answer the op, either antifoul it, go underneath and clean it or accept that you’ll have to take it out every now and again to clean it.

Wow, that goes back. Reards to Roger - we're living in Guernsey, based in Beaucette. Enjoying a late summer cruise and heading fro St Cast today.

We are just on our last leg of a brilliant week long cruise with Roger and Hellen on their Princess. We’ve been from Port Camargue to Sete, where unfortunately the lifting bridges to the Étang de Thau were closed for repair. So we continued west to Gruissan then back east to Cap d’Agde. We are now returning to Port Camargue which is their home port. They came to the Med by sea in 2012. Roger says he well remembers Beaucette and he sends you his best.

Hi everyone, has anyone found the best way to keep the paddle wheel clean on a large fast planing boat?
For example has anyone heard of a way to put a remotely removable cover over it?

Ours comes out.. have a stopper to put in the hole while I give it a clean. I think most paddle wheel logs are removable... cleaned mine last weekend as it had briefly failed to initially work the last time I went out.

and I totally agree, a paddle wheel log is not redundant. SOG & SOW both info required on a boat imo..
 
My DST800 is only in when I'm on passage away from my mooring. Once back I take it out and put the supplied blanking plug in.

None of the stories of non-working fouled logs resonate with me, I've had no issues with mine at all. I don't get why people would leave removable ones in, when the boat isn't in use. The cupful of water while changing them over isn't an issue once you've done it once or twice.

I used to do that, but was forever forgetting to put it back in.. :rolleyes:

I like that! Any idea about its price?

Besides (with apologies for the slight o/t), I've seen in their brochure that the thing is available also with a processor box whose output is NMEA0183.
So, I guess it should work with my Raymarine Pathfinder MFDs aren't NMEA2000 compatible.
I'm just wondering if I can expect to "see" only the three numbers (STW, temp and depth) in the ST60 instruments or I could also use that signal to feed the sounder and see the bottom profile out of that transducer, rather than the existing one (which is in-hull and not very accurate).
I'm actually skeptic that a NMEA0183 signal can be used in that way, but It doesn't hurt to ask, I reckon... :rolleyes:

ΝΟ P, no way!
NMEA0183 or 2000 for that mater just send the three values (I also have the DST800 which is N2K)
You need another sensor to do your fishy thing work...

no way to upgrade to that thing, ffs!!

LOL, +1.
I guess it might still make sense wherever tide/current can be VERY relevant, but in the Med, they must really count on folks with more money than sense, to fork out 1k quid for that thing...
No offense meant for Piers, of course - also because he does cruise an area where tide indeed does matter, as I understand. :encouragement:

Thanks V for the confirmation ref. NMEA not being able to handle graphic sounders, in hindsight it was even silly to ask, but hey-ho! :)
 
I'm hoping they come down in price, as I'd like one in the event that my DST800 dies, but there is no way I'd upgrade for the sake of it, as I've no issues with my DST800.

At the current pricing not sure i'd go for the ultrasonic variant.

When i enquired, the unit with a plastic through hull housing was about £1,065. The bronze housing (if you don't already have one) was £135.

Re working with other kit, I can't comment, but I'll be placing the operational requirement to my installer as a condition of purchase.

P, you're making me curious: you seem to assume that the bronze housing is necessary, but is it?
Afaik, with a solid GRP bottom, the chances to flex/move around the hole, to the point of risking to crack a plastic housing, are pretty close to zero...

+1

have two AIRMAR thruhuls both plastic. Last time I checked (this morning) boat was still afloat (and marinetraffic last heard of it a few mins ago...) :p
Did have 2-3mm all around the housing and used lots of 291i so there's space for flexing if there is any, but I guess all ppl do that.
