Re: Alternatives to Starlink
As an emigre I try to keep a tight rein on political opinion, but by the sounds of this thread there is an awful lot of buyers remorse going around right now.
It is the Information Age and Musk has revolutionized access to the Internet. I just wish engineers would stick to engineering!

Re: Alternatives to Starlink
¿ªÔÆÌåÓýJim you can program the dish to go flat. ?We have found that position to be rock solid and also less of an energy hog. ?As for that crossing we waited for modest conditions as that can be a very treacherous area if the seas kick up. ? The other thing up in British Columbia is you don¡¯t sail in the dark due to the floating and submerged logs. They could wreck your day.We usually connect pretty quickly, but candidly, with lithium and solar we leave it on most of the time. ?We almost always are motoring near the end of a passage as well so that helps our battery bank along wit hour 170 amp alternator.

¿ªÔÆÌåÓýIt is much cheaper and it gives you internet as well as VOIP.?For example something is broken and you need a schematic to understand the issue¡internet. ?If somebody gets hurt and you don¡¯t know how to deal with it¡internet.

Re: Alternatives to Starlink
So, how is starlink better than an Iridium phone when dealing with an emergency? I guess there are outlier cases when that's true, but it seems like if the starlink is there for an "emergency," it's not really needed. If it's there for work or entertainment, then fine. I'm certainly no luddite, but I'm also not interested in more technology when it really isn't needed. It becomes a distraction. |

Re: Alternatives to Starlink
¿ªÔÆÌåÓýWhat were the sea conditions?? We found that acquisition was time consuming or even impossible with rough seas, though once acquired, we never lost the connection. My guest, for the gen 2 at least, the startup phase where the
dish is rapidly looking around for satellite, doesn't like the
least bit on instability.? But once it has an internal satellite
map, it knows exactly where to look.? [The Starlink secret sauce
is that rather than moving antenna, it electronically steers a
number of transmitting elements.] On 2/26/2025 11:15 AM, David Lochner

Re: Electric Head with Macerator
Hey Tim,
Yes, you can rotate the base on most marine macerating heads - one of the best things I¡¯ve done for the family on our 38mkii. We are potty training a 2 year old and the kid tends to flush an entire roll of tp if not checked. The 5 year old isn¡¯t much better¡ The old manual head just started leaking from all seals. Electric macerating toilets have a lot less moving parts, power draw is low and they smell better (especially if converted to fresh water). Plus it¡¯s easy for visitors and doesn¡¯t clog or leak half as often. We used a model from 5 Oceans, but again I believe most bases can rotate on installation to fit the platform. We installed an air-gap fill and 3 way valve so that we can switch between raw water or fresh without worry of contaminating fresh water. TMC Electric Marine Toilet, RV...

Re: Hempel Bottom Paint
Hi Jay,
?
Hempel has been around for many decades.? They are a major supplier to the commercial shipping and offshore sector and have a full range of paints.
?
I am wondering if the sales rep mentioned "silicone" - there are a number of new products on the market that use this as a "fouling release" coating.
I believe that Delos tried a similar product on their boat but not sure of the long term outcome.
?
I worked on a number of coating research projects that included using fluoropolymers, PTFE additives, silicones and siloxanes.? I could never really find something that was a perfect solution although the fluoropolymers showed promise.? This is 25 years ago now.
?
Selectope (developed in Sweden) is likely the most promising technology available right now as far as I know.? Pettit has the rights to the product as an additive to their bottom paints and I believe they are waiting on EPA approval for use in US waters.? The EU has approved it so I expect it should be available soon.
?
I would avoid silicone based paints on your boat (in my opinion) as they may be challenging to remove in the long run and make it difficult to switch to another coating.

Has anyone heard of Hempel Bottom Paint?
At the Boat Show last week I spoke with a fellow who had a booth selling this non toxic, very slick, Hempel bottom paint.?
He said that as Europe becomes more restrictive about using toxic paints, this product has become quite popular.?
I wouldn¡¯t know.?
The samples he had at his booth showed the paint to have a rubbery ¡°orange peel¡± texture that at first glance you¡¯d think would be dreadfully slow. But when you get it wet, it¡¯s super slick, surprisingly so. And that not only gives you greater boat speed, but keeps the bad stuff from sticking to the bottom.?
Or so they say.?
He said there will be growth around the boat when at the dock, I think he called it a shadow, but once the boat goes in motion, it all comes off.?This includes sailboats.?
Putting it on for the first time seems expensive and labor intensive. You need 3 separate products (it will go over existing bottom paint), the final coating being this slick stuff. It also works on the prop.?
It¡¯s $400 a gallon, two gallons for my 36¡¯ boat (he thought maybe 11/2? gallons). Once you do the first application using the 3 products, from then on it¡¯s just putting on the slick stuff, every two years.?
That¡¯s what he says.?
I¡¯d be curious to know if anyone has first hand experience with this product.
BTW, it¡¯s only been a few months (but oh how things grow in South Florida) however I¡¯m cautiously optimistic about my Sea Hawk Biocop tf to date.?
