So where's best for a retube? Help.

[jambo]

Paul I use to at the end if the summer loose a hell'va speed. Culprit in the mail was all the shit hanging on to the hull. I took the plunge and AF'd
Do it every year with UNO mainly because over the season it erodes of and there ain't much left by autumn. The other thing I did was I was very harsh regarding all the 'stuff' I had in pods and lockers I now only carry what is necessary. Made a hell'va difference now have same top speed all season and I don't have to keep scrubbing her arse during the year. I also use that spray AF clear kind got it from Force4 on the tube bottoms you need to renew that every three months but does the job.
Hope that helps

Jambo, we are ok re weed etc, yes speed drops off a bit (few mph) at the end of the year but the AF we put on keeps most of it off other than a bit at the back.

At the end of the year there isn't much AF left on as it comes off by design.

For some reason last year and this the speed has REALLY gone, even when we launched round the island for first time this year, we only got 38 mph. That's rubbish. I was out on Sunday and it was SLOW. Something is a miss.

I can only think it is the extra cladding we put on, making it a good inch lowere in the water, then with the extra weight and slack tubes another couple of inches. That increase in wetted area can be the only reason.

Going to pump them right up and see.... when i next get a chance.

Will go from there.

I remember an article in R.I. called the furtive knot robber. The nub of the story was a large rib circa 7.5m tornado with a verado engine (275 hp I think) was left in the water for a few weeks circa 3 weeks. The rib ran fine before it was moored up and like sh*te after the three weeks. The boat would only barely plain. The Rib was lifted out and the hull pressure washed this had the effect of returning the boat to its original performance.

1. Pump the tubes
2. Dry out the RIB (check recesses)
3. Take off all the excess kit
If that doesn't help:
4. Test the compression (I know, it's only 5yo, but it's a two stroke...)


I doubt if a bit if cladding is making a RIB lose that much buoyancy.

Before you AF next season, give the hull a quick sanding.

The only time I have heard of that much speed loss if it was not any of the forementioned was indeed water thru a bad hull and the the inner of the hull was wood and it was like a sponge, held a hellva water

Two stroke mick: what was the reason?

All

A) what's the make up of the Humber OPro hull/deck. If its got ply in between the grp, could it have got in?

B)how would you find out if it has?

C) what do you do if it has?

[QUOTE=Rogue Wave;545281]Henshaws are fine. Eurocraft (SIT) (I think they are different companies but some of Eurocrafts talent set up SIT). are ok but I always use Paul Tilley He's very good and cares about his customers and he's a man you can trust.

in thory yes you can but it will need to be reprepped and will always look older than thee tubes. Few retubers would want to do it as its going to make their work look iffy

Do you Know DM hes very good at sorting that out failing that Mike at Osprey

QUOTE

Some people coat the underside of the tubes with Marge or dripping as that prevents the barnacles from forming. Somebody will probably be along to correct me and tell you it's Tripe but its that kinds stuff definitely not butter

ive used SIT twice, bang on both times, next retube I need will defo be with them!!

Ha! It's been done by some I believe!

Tony/Steve/Chris- hmmmmm

[colcreate]

Dave Cowell of North West Ribs (ex Eurocraft) did a couple of good jobs on my rib North West RIBs & Inflatables - boat repairs he is in Wigan so worth a call.

Easy If he loses too much weight then his Snickers might fall down

Don't think so, no air leaks and valves are tight. Nowhere for it to get in. Good thought though!!
