are anodes needed/used on 11 foot dinghy

I have just picked up a second hand aluminium dinghy to use as a cartopper when caravanning .There is a small amount of pitting in the aluminium but nothing too bad but was hoping to prevent any further deterioration . Having always had glass boats I was wondering if anyone uses sacrificial anodes on there dinghy . If so , where do you put them . Do they need to be placed below the waterline ( could be an issue on a small dinghy ) or would bolting one to a seat be as effective.
Any info would be appreciated .

360 reads and no comments . That surprizes me very much . Would not had thought I was the only one wondering about this subject.

None of my tinnies had anodes on the hull

 Motor only, careful with any fittings into the hull, duralac screws.

I know about duralac but probable more concerned with aluminium boat sitting on steel roof rack for extended periods of time.

Never seen an anode on a tinny bud, sounds like you have normal wear and tear and some people tend to clean out the "tinny" with little to no care from saltwater.
Without seeing a photo it's hard to say what's normal or what needs attention.
Leaving saltwater in the bottom of a hull is my pet hate and the other that closely follows behind is finding small sinkers caught under the floor or ribs.
I tend to go overboard with looking after my tinnie's but in saying that I have owned 5 now and never sold a tinny for less than I paid.

 Paul, as above it's all about care and cleaning it properly after use. You should be ok if the pitting is minimal.

Thanks everyone . Yes the pitting is minimal  and sounds like it is from

lack of care from previous owner . As stated , I’ve never owned an alloy boat before so

sory if the question sounded a bit silly but sounds like anodes are not required

Don't be sorry bud, it's a pretty valid question, I think there is a facebook page called "Tinnie boat mods and ideas" and it has guys on there that just love to pimp out their boats and there is some pretty useful info too.
