hmm, interesting point about the distance between the colours and the running light - I hadn't read anything about the distance between when I designed it.
- although obviously makes sense the further apart the less the lights will merge - I did realise that. The bi-colour actually works out about right - and when you consider everything in a 4m rib is above you (except the v.very far away) I don't think it should disable it much. but...
To be honest these lights are more for pose value than purpose which sounds stupid, but to be honest it's better to have some sort lighting if I get stuck out in the dark than none (I don't have any serious intentions or interest in ribbing in the dark in a boat this size!! - just day use). besides all you really need is an all-round white - I have a separate stern so at least i'm visible all round and the white is well clear above head height. Maybe I should have just put on a single white at the top of the mast. and left off the bi's.
Stuart, the tank does take up a lot of room from the console obviously, but I can still store two oars, a large pump and one of those large orange canisters which has everything I need in it (fire ex(s), tool kit, first aid kit, spares etc and also an offshore flare pack.
It does disable quick access to the back of the dash I admit (although I too have just bought a 200mm inspection hatch to install in the front of the console! - I have also added a locker with a door into the front of the console as there is nowhere to put spare killcords, vhf, keys etc in a rush.
I can still easily get to the battery though for a jump or charge which was essential obviously! To access the electrics you have to undo the filler pipe and the tiedowns and the tank drops back. When i wired up the electrics in the console I squeezed upside down into the console. It was painful and I ached for days after!
Re the engine hp rating - Ribeye did a lot of playing around with the badging on their ribs until about 2004. Mine is rated 60 believe it or not, and I would admit it is slightly overpowered. But it's only overpowered if you use it carelessly! - it's great to have the extra power there - I think for this size boat a 50 is about right. (these are also quite heavy 4m ribs!)
