Get a Targa more like.
Targas roll like any other boat and there's a big brown stain on the carpet of our old T48 to prove it
Get a Targa more like.














What has gone wrong is that Volvo dont yet make powerful enough IPS drives for a boat this size and hence builders have to use 3 not 2. I must admit I do not understand SL's decision to use IPS on a boat of this size and type unless its real purpose is to be a beach club that moves from one anchorage to the next rather than a proper cruising boat. But who am I to criticiseSanlorenzo SX88.
I didn’t actually look round this but saw it from various vantage points around the show. Very striking visually with not one, not two but three IPS drive units. Might it be said that something has gone wrong when you have to whack 3 engines in a boat?
The Swift Trawler 50 has a dumb waiter and there is another that I’ve seen with one but I’ve forgotten which boatBeing of a younger generation in my late 20's I have never lived through the internal steps era but I do have a question. Why do boats not feature a dumb waiter system? I don't want stairs getting in the way but I'd love an easy way of transporting food, drink and stuff between upper and lower areas. It's also a lot safer than trying carry things.

Absolutely not, if by IPS you mean pods in general.Is there possibly a contradiction between the trawler concept and IPS
Most economical possibly, but for the builder's P&L statement.I'm sure someone will be along in a sec to say the IPS was purely to give this 88 footer some more cabin space and the pro skipper some help with docking.
You have to think it was deemed the most economical and range extending for an semiD of this size.
Not sure I understand your point about 'diagonal' thrust. Surely any lateral thrust from one drive is offset by the other drive?Agreed - as already debated in this previous thread.
Otoh, even if IPS are right at the top of my personal OMDB listrolleyes
, I believe that there's some technical logic in triple installations, aside from the need for enough power.
In fact, the fundamental flow of IPS is that they are designed for planing boats, whose hulls are V-shaped.
But rather than considering this very obvious constraint, VP thought that asking boatbuilders to make flatter hull sections in the area where IPS pods must be positioned was a good enough workaround for reducing the listing introduced by diagonal thrust upon steering - with results spanning anywhere from barely acceptable to downright dangerous.
As I said above, if you believe the test data in MBY, IPS delivers little or no fuel economy advantage over shafts for bigger, heavier flybridge boatsYou have to think it was deemed the most economical and range extending for an semiD of this size.
Nope, M. I can see why "diagonal" alone ain't self-explanatory enough, sorry for that.Not sure I understand your point about 'diagonal' thrust. Surely any lateral thrust from one drive is offset by the other drive?
Most economical possibly, but for the builder's P&L statement.
The SX88 is rated for speeds exceeding 20kts, which are above semiD also at this size.
Their proper SD vessels (aptly called SD range) are all shaft powered, bar none.
OK understood now. I have read that IPS boats tend to have wider turning circles than shaftdrive boats at speed. Maybe the steering movement of the IPS drives is restricted at speed to reduce this additional vertical component and keep listing to an acceptable angle?PS: just in case the above isn't yet clear enough, there is no offset of the vertical component, in a twin installation.
It's actually the other way round: when steering say to port, the vertical thrust introduced by port pod pulls the boat downward on port side, while stbd pod pulls the hull upward on stbd side - hence both concur in making the boat list to port, much more than she would do for the steering alone.
Well, you might remember that I'm a supporter of SL as a builder, generally speaking.I'd be surprised that on a £8m boat with top end fit out and respected design that they chose the engines purely to boost bottom line but maybe you're right.
