Decided to give the boat a clean before a cruise to the west county, so booked a session at the Cowes Boat Lift. Was a bit blustery when we arrived and a little intimidating to get lined up, but not too bad once you nose in and are between the large arms.

The list itself is a bit nerve racking when you are wondering what's stopping the weight of the boat being taken by the props, but all makes sense once you see it lifted.

Confidence is helped by all of the equipment being shiny and new. There's a ladder to climb down one of the arms, not for the faint hearted.

The antifoul and anodes were done in February, so I was assuming quite a bit of fouling. In fact it looked in good condition. So much so that I wondered why I was bothering with the lift, but at now I know that assuming future year's are no worse, it will go a season without any attention. The anodes in particular looked brand new.

The guys doing the cleaning were diligent and pressure washed, followed by scraping and when rubbing down, finally another wash.

In all we were in at 3:00pm and out about 4:00pm and off to Yarmouth.

The weather was better than expected, particularly sea state, so we kept going across to Poole.

As it was still not too bad and we were running at 28knts, we slipped around St Alban's ( a bit rough for a short time) and arrived at Weymouth in time for dinner. Harbour staff at Weymouth very friendly.

Only downside was surfing down the swell in the following sea at speed saw us push the bow down (I slowed up to avoid stuffing the bow) but we were regularly pushing out very large amounts of water either side. The portholes weren't tight enough for the pressure this caused and we got water in the front cabin... not terrible, but damp carpet to dry out!

Next challenge, round the Bill and on to Dartmouth...
 
Hi Kevin

Clever innit that sea lift? Following on from my pm to you about this last week, I was keen to change the anodes on the T40 so we had a go at the sealift on Friday afternoon. All very straightforward and the guys working there couldn't have been more helpful.

My only criticism was that ladder - it's not high enough, you run out of things to hang on to as you climb over your rails. But all in all it was very easy and I'll use it again.

Cheers

Ladder might be better positioned for sail boats.

How long had your anodes lasted? I'd thought of them as things to replace annually, but only the ones on the trim tabs showed any sign of wear at all?

Anodes and antifoul were last done in November 2009; hull antifoul was in good shape; drives were terrible - it looked like they hadn't been primed properly; drive anodes were very spent, I don't think I'd have got another month out of the shield anodes. Trim tab and hull anodes were fine and I just cleaned them up a bit and left them there. The tie bar anode was ok but the replacement the VP dealer had given me didn't fit anyway. I also have an anode on the s/s bar that supports the bathing platform, and it was also fine.

If I keep the boat I'll fit an isolation transformer this winter, and it'll be interesting to see if this slows the rate of anode wear. When I put a galvanic isolator on my T37 the change in anode life was really noticeable.

Wot, no galvanic isolator as standard fit by Fairline? Good job you found the anodes were well worn, otherwise the bill could have been pretty horrible! :eek:

"If I keep the boat".......?????:confused:

Not on the T40 (or on my previous T37); not on the Princess 42 either. I think SS fit them though.

Ah yes, I'm just idly thinking about a change, I've done 170 hours on the T40 since the end of May last year. We'll see.

Came across an article describing Galvanic and Electrolytic Corrosion, see below, never knew that other boat / marina could be a cause of accelerated corrosion if connected to shore power

Yep; it used to be that a galvanic isolator was a cheap and lightweight way to stop these stray currents through the common earth, but as I understand it, the design of switched-mode power supplies defeats these and the only sensible remedy now is isolation transformers - which are expensive and heavy. Or, I guess, to not use any switched-mode power supplies on your boat.

Nice Pics K, thanks. Boat looking v good!

The aft hull support could have done with being a metre further back -there's an awful lot of cantilevered hull there!

Good that your anodes are ok, but I'd suggest don't extrapolate and assume all will be the same next year. You could get a dodgily-wired new neighbour boat in your marina anytime, and that changes everything.

Yup, those isolation transformers are big and heavy - i posted a pic on my "in build" thread the other day

They moved us back and forward a few times before they were happy to lift it fully, there was also a fairly heavy bow line from us vertically down to the platform. Made me nervous seeing it out of it's element but not as much as slings.

Will still keep an eye on anodes then, the lift is quite a quick way to do it, and at £200 didn't seem outrageous.
