'Domestic' Seariders are 4.00m, 4.70m and 5.40m
The max power ratings are 50,70 and 90 respectively.
They come with a flooding hull as standard, but can be specified with a dry hull instead. They have a bailer for draining the deck.
The 4.7 Searider with a 70 2-stroke (Yam is nice ) is a very capable boat - I saw one yesterday with a 60 4-stroke Soozook, which looked good, but I've never been on one running a 4-stroke so don't know what the balance would be like.
I think the Ribcraft 4.8 is around 5k for basic boat with single jockey console and steering. What sort of money is a new 4.7 Searider at the moment?

Has anyone got a photo of the flooding hull?
Is the flooding hull the same as the atlantic 21 and 75?
Not sure how much new SR's are, didn't realise they still made the smaller ones!

SR4.7's are great if you can find one - I'm not sure if they are rare but the 2nd hand market on them is pretty limited. They are basically a short versoin of the 5.4 with same diameter tubes etc so a lot drier etc that the SR4. Makes a brilliant option for towing and storing in a garage. A bit narrower than the RC so they will (apparently) fit through a standard garage door!

The flooding hull is essentially and inner and outer hull. Outer has a large hole in the transom at the stern and 2 air ports at the bow. There are also bouyancy tanks in the floor cavity to limit the amount of water ballast and also ensure the engine has some support when the flooding hull has flooded

Search on the forums for searider as there are a few folks who have removed the inner deck to make repairs and you can see the makeup really well.

(I really like my RC - really impressed with the build quality and soft riding hull. Email post sales support is sporadic but they are good if you get them on the phone).

So whats the advantage disadvantage of the flooding hull?
If it fills up at rest and emptys under way whats the point... think I'm missing something somewhere!

Flooding Hull

Pro:
Stability at rest - hull void full of water gives less buoyancy, so the boat tends to bob about less

Easier to get people in from the water as the boat sits lower in the water.

Cons:
Boat will take longer to get onto the plane, as all the water has to be ejected through a smallish hole in the transom

Take care when fixing things to the deck

Boat sits lower in the water at rest, so is more likely to take water over transom in rough seas.

ribcraft price

I was tempted by the review in rib magazine as well, however, the price stated in there "as tested", i can only assume that is the price of that actual boat - i.e second hand. Call ribcraft, and get a quote to the same spec - i think you might get a shock, then ask them about lead times for another shock.

My 4.8 RC fits in a standard garage with the tubes deflated and the engine trimmed down oh and the draw bar on the trailer removed, nice rib, well made, motor is a mariner 60hp 2 stroke had about 32 knots with 2 1/2 on board(son age 8) and about 40 litres fuel, props got some damage though so should get a bit more with a new SS un,

So they shouldn't be any problem in blanking this and the two holes in the foredeck off?
Is it worth forcing closed cell foam in the void then blanking off...

If you want to block the flooding hull, the best way is simply to cover the hole at the back, and fill the small ones at the front. That way, if you want, you can convert it back later. Foam probably isn't a very good idea, as you won't be able to change it back later, and it will become water-logged and weigh the boat down. The flooding hull isn't a major issue when planning; my 4 meter will plane in about 10/15 seconds with 4 on board with only a 25 4 stroke Yamaha.

It would be closed cell foam so it wouldn't soak up water.
Might just see how it is with the flooding.
Been looking at this:

http://cgi.ebay.co.uk/ws/eBayISAPI.d...ME:X:RTQ:UK:11

How much do you reckon without the engine and with a trailer... roughly?
