OK guys the moment of truth as we saw it today.
Just got back from the beach. Weather is GREAT just a little breeze NNE and sea state calm. Ideal conditions to race a boat.
I will not bother you with photos but with the facts.
The set up: FALCON 700RSR, 200VMax Yamaha with 21" Yam Pro SS prop and 5bhp Aux, A-frame, 100 ltrs fuel, full tank with oil, spare tank with 35 litres of fuel, 7kg anchor, 15 mtrs chain, total of 100 mtrs ropes and 10 life jackets and a life raft. Two persons about 90-95 kgs in weight each. Wind force 3 NNE. Sea state calm. Engine is set up by Falcon in SA and if you need any clarification as to where it is in relation to the transom, hull etc I can give it to you, but right now is too hot to go out and measure things. Area Assimakis beach near Cape Sounion.
1. The problem with the boat leaning on the port side:
Yes it does, BUT only at around 40 knots. Before 40 knots and up to 35-36 or so and also pass that point and at 43-45 knots it corrects its self and is on the straight again.
: The boat is very (I MEAN VERY) responsive to trim. As I have said before. With full trim down the nose sticks in the water and is very obvious as the boat leans completely forward. At trim on 2/2.5 (on the Yam trim gauge) the nose comes up quite a lot and up to 4 the boat gains speed, revs go up and comes out of the water completely. At trim 4.5 the boat slows down and you get a noise from the prop. At trim near 4-4.2 if you hit any waves the boat waves up and down (is this the right expression?) we call it in Greece that it behaves like a dolphin, and the trim needs to come down again just a notch and this effect stops.
On a 380 deg turns and at about 30/32 knots with trim at 2-2.5 the boat turns without any problem and comes out of the turn with the same speed as when it went in the turn. On 380 deg turn and at about 47-50 knots with trim down to 1/1.5 the boat tends to slide just a tinny bit mid way and then you can feel the hull (with a small juddering not to the hull but to your body - if this is the right expression again) getting its grip again and carry on as normal. Again the boat comes out of the turn without having lost speed (or in some runs we did lost a couple of knots). There was no prop ventilation at any one point except when we tried a turn at WOT with trim mid way and the result was as you would expect.
Cruising is comfortable to very comfortable (in this very nice and calm sea and smooth wind state conditions) at 33-35 knots on GPS, 3800 revs and trim at 2.5/3.00 on the Yam trim gauge. At WOT and at 5700 revs with two persons onboard, trim at 3.6-4.0 (this Yam trim gauge goes up and down for some reason but they say is normal) top speed on GPS was between 54-56knots. We made quite a few runs so we got the slowest and the fastest. We felt that with less weight on the boat it may have gone faster, but this is another matter.
At no time we felt unsafe on the boat. I suppose this is because of the bucket type seats I have on it (driver, co-driver and aft bench are all bucket type). The boat felt fine. We felt that the seating arrangement you have described previously (not bucket type seats) is NOT A SAFE arrangement for this type of boat.
As I said in previous posts again today we found that to handle the boat correctly one has to play constantly with the trim and the throttle. You cannot just let it go unattended (which I think was the case). We feel that this is a specialists boat (if I can use this expression) and not a boat for mainly recreational purposes (although I use it and I'm happy with that). We do not believe that it should be compared with those RIBs of recreational use. As we feel is comparing a F3 or F2 formula car with a normal car for the road.
As far as I can see my boat looks OK. I'm happy with it and the only thing to say is that the upholstery needed to be a bit more rugged for sea use. However, in the boats that I've just got (640SRs) the upholstery is much (a lot) better than on the 700RSR, I got 2 years ago. I need to see this boat you all went on.
10. Other comments:
We feel that to drive this boat correctly, one needs to know how to drive racing boats correctly! May be Cookee (and I'm not joking) should have a go at it. Also you need a lot of time to get familiar with this type of boat, which is very sensitive to even the slightest change on trim, engine position, engine height, engine weight, prop size/pitch, weight distribution etc. The slightest change unbalances the boat.
I do not know if I covered everything but I'm full of salt, so I'm going for a wash.
I have tried to be as impartial as possible and if you feel that I have not (writing in a 2nd language no matter how well one commands is quite difficult you may appreciate) please feel free to make your comments and will try to clarify any points that you may have. If you also want to see any photos or a video of today’s test run, please let me know and will try to download them.
