Any thoughts on me changing my boat?

As much as I like the Targa range, they are walkarounds and I do want some kind of cabin in the front. And they do a 25 which is pretty good too.
Interestingly though, Hardy do a 24 Fisher which is an interesting looking boat. I'm starting to like the look of this type - very practical too.
 
I know you found the Flipper outdated, but..

Thanks Spi D.
It just goes to show what good design and achieve. And that's the shorter version I believe. I'm not sure if they make the 760 but that offers even more space. There are certainly a few overall differences but essentially they don't seem to have changed much over the years. Def food for thought....
I'm still considering some kind of DS boat as well, trying to be as open minded as I can.
I just can't help thinking that most semi-DS boats are just under powered planing boats? If so, surely they'd use more fuel pushing against the bow wave than a planing boat that has just got on the plane and throttled back to a minimum planing speed?

When you know your intended use you'll get closer to best suited design.
Planing hulls are designed to perform in speed ranges where the hydrodynamic lift is larger than the boat's displacement - ie. where the boat skids on top of rather than through the water. These designs are best either at idle (where many need a lot of work at the helm to stay on a somewhat stable course) or above planing threshold. In conditions (wind/waves) where speed is not useable (comfort suffers), they get outside their designed preference and any speed where power (fuel) is used for other purposes than forward movement (keeping the bow high, dragging a wash) really ruins mpg. Some planing boats have a hull design blended with a weight distribution and driveline that make them 'hybrides' as they will handle semi displacement better than their type suggest.

Semi-displacement boats are designed to perform at all speeds without planing. Can be any speed (depending on power), but of course high speeds without lifting the hull out of the water will take more fuel. On the other hand comfort and capability is better in the mid range, where the planing hulls really do not want to be. At low(ish) speeds (around knot=waterline length in meters) they are fairly easy on the fuel. As opposed to displacement hulls the SD will slide on the water at higher speeds - hence the "semi" definition.

All IMHO, of course :)
 
Thanks Spi D,
Yes, I know/understand all that, but useful anyway. My query is specifically about the fuel usage of a semi-ds. On my reasoning, a semi-ds would use more fuel (once it's over it's ds threshold) than a planing boat running near it's lowest planing speed. I doubt the two speeds would be that similar either. I guessing here, but I suspect a ds boat at say 13/15knts would be using significantly more fuel than a planing boat at 20/22kts. But I take your point that the ride will be much smoother in rougher chop. So is that why ds boats exist? I've never owned a ds boat and perhaps don't really understand their market segment. A couple of the boats on my list are ds I worry that fuel usage will be significant. I know that ds hulls are limited, no matter how much horsepower you've got, but at least you're not tempted to go faster, because you can't. I never really run my planing boat as ds speed, it's always a few knts over, partly because it runs straighter line, yes, but also simply because I can, even though I know it uses much more fuel.

My CI 32 averaged about 2.25 mpg, usual cruising speed about 13- 14 kts, max about 18 kts. The CI 22 averaged 4.5 mpg, same speeds.

Hello, I can see my Flat in that Photo. If you need to know more let me know as it is 100yards from my building!

Wow, it's a small world after all. Still thinking but I doubt I'll do anything until the new year now, so might take you up on your offer if she's still around. Thank you very much.

Thanks John, that's good to know. I assume they're both ds boats then? something I hadn't realised. The 32 looks superb and much more social. I think that's what I'm aiming for now, something that covers more leisure than pure speed. After all, I can also buy and Fletcher 15 for the rallies :-)
Besides, Julies hates going fast unless it's glass, and how often does that happen?

Oooh - I scent another road trip coming up!!! You're just trying to exceed our Scotland trip aren't you? :p

(I'd be up for reciprocating the help, but less sure about towing that back with a Land Rover... Might have to be on the water! :excitement:)
