I have two questions for the forum tonight and would be grateful for any advice- these are pretty basic questions but i have just got to get it into or rather out of my head!!

1)In your experience do you think that 14mm nylon rope hold a 27ft 3 tonne motor boat secure in the marina?

2) I currentlly have one single length of springing line that attaches to the marina pontoon at the front end with the soft eye , then it goes to the centre cleat on boat then down and tied off onto pontoon cleat at the back end.I think i would rather have two lines with both soft eyes fixed on the centre cleat on the boat then they both extend to the pontoon cleats front and back.Sound sensible to you?

thanks for any responses.
 
14mm nylon is more than enough for your weight and size. Keep an eye on it for UV degradation (it will go hard and unyielding)

To fix your boat securely to the pontoon, you need

1 a bow line and a stern line to prevent the boat moving away from the pontoon. These are made fast at as near 90 degrees as poss to the pontoon.

2 fore and aft springs to prevent the boat surging for'd and aft. These should be as long as possible to make use of the elasticity of the nylon, and really from the bow right past the stern, and from the stern right past the bow. Only to a halfway point is really not enough.

Don't strap the boat in so tightly that she cant move against the fenders. All that achieves is to turn a 3 ton boat into a 6 ton one, adding the weight and inertia of the pontoon to that of the boat. Elasticity and some movement are needed to absorb shock loads.
 
Haha 10 strands of baling twine =14mm!!
Seriously Searush how did you know that am from farming community or was that a guess?

I thought all Marina boats were tied up with baling twine. :D

I live in a rural area meself so it's a standing joke in the family.

When I was gainfully employed by BT I occasionally gained access to 6mm poly prop draw rope that is left in duct runs to enable the pulling in of new cables, so a lot of that has been used for various nefarious purposes over the years. More recently I have graduated up to ex-climbing ropes. :D

In fact I am currently moored over night on a couple of climbing ropes used as a temporary strop. CHT provide bouys, but not the bloody strops, damn nuisance when solo in strong winds & tides. Took me half a dozen attempts to thread it before I could have me tea.

They will keep your vessel secure. I bought 14mm 10m warps when I first purchased my S23 but my wife found them too heavy and long to handle on a day to day basis so I replaced them with 6m 12mm warps. My vessel is 25ft
