specific rules and regs question

Hello one and all,
Obviously the boat in question is D2S.
Pash 1 has advised me that it will run in "Marathon " class.
I have a copy of the latest PB1 rya rules etc, and from speaking to many of you at "Drivers" I am getting conflicting answers as to what is and was is not acceptable installation on two main items -neither of which I can seem to find in the PB1 rules for clarification.
If you choose to respond please quote me the relevant section/rule that applies.
Question 1 :- The engines have a "gill" type manifold, from that they rise and turn to the rear of the boat in in a wet twin wall configuration -- the section from the turn to the rear is a single tube combining the exhaust and the coolant. -----Can I use a suitable rubber sleeve to connect these two pipes, if not please quote the relevant ruling that I need to look at.

Question 2 -- "In board drive shafts" or prop shafts if you wish, the connection from the engine/gearbox to the stern drives.
From my car racing experience a drive shaft/prop shaft should always have a restraint method should it decide to depart company from the rest of the transmission, as a matter of course I would install a couple of "prop catchers" per drive shaft to prevent, should it detonate, ripping a hole thru the hull. Also for engine room safety I would also have a cover over the shafts to avoid personal entanglement should you be there when it is rotating.
--What are the defined specifics (if any) for this? Again please quote the section or rule I need to look at.


Thanks for any useful and informative advice.

Regards
Budweiser

If it ain't in the rule book it's free, although I've not recently read it to confirm.

However, both of the things you suggest are fairly standard practice.

Standard practice

Thanks Matt,
I have gone thru the whole of the RYA some 260 pages, but can not see specific definition nor recommendation even to "standard practice".
This however contradicts with "advice" given.
Does a standard practice definition exist, that could be used for scruteneering?
I only ask as "i checked the PB1 rules last night/recently for you, and you must do this" scenario.

I am still wondering what size paddles the boat should have stowed, and also where and how to store an alternate means of propulsion that is capable of 5 knots for 35 mins for a boat that weighs in at some 6 tonnes plus fueled --should i arrange to borrow some scull oars fromm coalporters? and nail an outboard on the back for good measure?

It's no wonder racing's going down the drain really is it! You'd think they could relax a few of the rules a touch to make life easier for us!

Surely that's a requirement for single engined craft only.

To understand the rules a basic level of reading is often required!

The only rules that will affect you are those relating to the design of the manifold - unless you are looking at class A,B or C. Rule 4.2 defines the type of manifold you may use. Some things are specifically excluded. Items that perform in the same way as items that are specifically restricted will probably be deemed illegal. The connection however is free. If you are conserned, you should ask your club representitive to query the facts with the ORC or seek written advice from the SAT committee. Get the answer in writing.

This is specifically not covered in the rules and should thus be regarded as 'free'. However.....If you are conserned, you should ask your club representitive to query the facts with the ORC or seek written advice from the SAT committee. Get the answer in writing.

I do not think that advice given in this forum will hold much weight when you are disqualified from an event.

An alternate means of propulsion is specifically only for a single engined boat. I guess you would find that would apply to the smaller craft entering, so a small outboard could be a suitable option - think of a 25 footer at under 2 ton.

The type and style of paddle required is not defined, but you would need to show that you have some reasonable chance of manouvering your craft with such paddles if required. So my choice would be a plastic/aluminim 550mm by 300mm paddle with a suitable shaft as a solution unlikely to bring the paddle into question by a scrutineer...
