Pile Mooring - Mooring Line Stretch?

Greetings all...

I need some expert advise on what seems to be a simple issue but drives me nuts

My baby - a 25 foot tophat - is on pile moorings in an area that has strong currents - up to about 4 knots.

The issue I face is that the distance between the pile is about 16 metres and the boat is only 7.7... so there is about 4 metres of line out from both the bow and the stern.

The rings on the pile itself mooring line is about a 1 metre above the highest tide and about 2 metres above the lowest tide...

Ok, sorry to ramble - just trying to paint a picture.

When I first moored there the person before me advised that I should tie off loosely so that the boat would drift a distance of about it's beam on the change of the tide... the mooring is not perfectly in line with the piles... but this means that at high tide the lines are in the water and getting algae growth etc. The algae annoys me and also the fact that my boat moves around so much...

Looking at the other boats does not really give me a good idea as they are all much larger and on level with the mooring piles... but they do not have lines in the water at high tide and taut lines at all time.

Heres the question Should I be tying off tight, or near tight, and trusting that the lines I use will have enough stretch in them to absorb the movement during the tide? Given there is basically 8 metres of line out to absord 2 - 3 metres of movement can I expect to get this from the nylon line with out ripping out deck fittings? I am too scared to tie off tight at this stage as I have visions of breaking something.

Any help greatly apprecaited.

Thanks

Karl
