Sort of although after a few minutes the waves have put mine under water again and the boat slowly fills.

That's interesting.

Do people raise (and tie) their tubes/trunks at anchor or when in harbour (for example)? Is this good practice?

To be honest, I've never given the tubes a moments thought. They're down when I head off from the dry stack and down when I come back - I never touch them.

I lift mine when I leave it on the mooring.
If I know I'll get quite a bit of water on the deck then I'll just leave them down till I'm back in the harbour.

Because I'm so terrible at remembering to lift them back up I tend to leave them up unless I need to drop them to clear the deck.

You can tell form my questions that i am a bit of a novice in respect of these things... ready to tackle the job but wary of screwing it up! Any advice gratefully received.
Cheers

Another handy tip - forget cleats on the transom - lead the rope forward & put the cleat near your seat. Then you can open / close as required.

your just down the road!

Yeap I work at Swanwick. I'll come in soon for a bit of advice. I was a bit concerned about weakening the transom by drilling. What soer of size does the hole need to be? Does it matter where you drill?
Thanks
Dave

I've got two trunks on mine and it hasn't affected the transom.
As for position inline with the deck and out of the way of the prop is best!

Nor mine ,,lol over kill i know on a 3.5 s.i.b.,,,though they do clear a boat full of water in less than a minute .
its not a bad idea when fitting the draw string to put a small eyelet in the trunk , opposite the edge your fixing it at and run it through that before fixing line off at the trunk ,,that way when you pull it tight in the closed posistion it then has the effect of closing the trunk flat so stopping any water/spray from funneling down and back in the boat .,,,As you can just see in the 2nd photo,.,,,i have seen a few trunks set up looking like a wizzards sleeve,, then they wonder why theres always water getting back in the boat .......looking at chewys earlier photo he has his set up ok ,,but i cant help wondering if its a handgranade resting under the nearside wheel .
