Well that screwed that logic then didn't it?

Other possible solutions:
1) Crap diesel
2) Everything else posted here
3) SWMBO has put on weight.

I seriously suggest frank family discusssions of points 1 and 2 only as number 3 might result in ugly scenes,

Re: Logging off..

I'm not bothering with a will. I'm going to leave all my worldly goods to a boating charity well before I go.......somebody like Fairline, Princess, maybe Sunseeker

Mike - you say the stern gear is still manky. If that includes the prop, you should deal with that first and see what happens. Scrape of all the gunge and give it a good rubbing down with a med sandpaper.

Re: Divers etc

It's a small differece in absolute (kelvin) temp so not that.

Much MUCH more likely the condition of the bottom. Most difference is the props, and they need to be metal-looking (shiny shiny not really needed). I think i worked out that the props "see" something like six times as much water as the hull per mile and the drag at elevated propt tip speeds will proportioanl to the square of speed, not the speed (like flow over the hull) , so sthe odd barnacle here and there on the hul makes less difference, its the props, the props, the props.

Follwoing advice here, i have a tank and jacket thing, not qualified but been on a day course it's only 3 feet down, and the whole kit cost only 400 quid for 2 sets.

So, yesterday could not pull more than 24 knots flat out. Today 45 mins scrapety scrapety til the last of the air ran out and then 29 knots. But props and hull not fully clean, so will get a bit more yet. This is not a quick job. I have a small scraper for curvy props, and a scraper 8' wide for the bigger areas. For 300 euros i would want a 48footer very blimmin shiny, but hiring a diver hereabouts is 100 euros in aug to get a rope off.

If u don't fancy the scraping/drowning option, ask Murray how much for a liftout and HCl acid clean at la rague (makes everything gleam in 10 seconds, really) and it will compare well with blimming 300 effing euros ouch ouch ouch. Or it might be around than but at least properly properly clean like it was in majorca, and in france earlier. But having the kit is useful.

Re: Divers etc

Thanks, Matt, I'm sure you're right about the props. They're not badly fouled but they're certainly not smooth as in hydrodynamic smooth. I was persuaded by my 'man wot does' that diver @ €300 would do as good a job as lift out by Arie De B @ €1000+. Seems this is not true
Ljs mentioned simple diving kit. Would'nt dream of diving into E Channel water but may be sound investment for Med
You back then?

Re: Divers etc

Nope, in the internet caff, back this w/e. As before, a girly on a next door computer is reading her email and saying oh gawd, oh no, oh gawd.

1000 doodars sounds blimmin steep for a lash with 20 quids worth of HCl.

I was planning to rig up a hydrochloric acid dispensing/brushing thing for use underwater and kazamm clean the props with a liftout, using a pipe and tank of the magic fluid attached to a cleaning brush normally designed to dispense water up through a hollow brush. But, sanity has so far prevailed and the brush thing is unused.
