Avon Searider 6.0 project
This is the 6.0 Searider that I got my hands on a few weeks ago. Previous owner had a Verado 175 on it. I got the rib unpowered to put my spare Honda 150 on the transom. I might do a pair of Yamaha 70 2 strokes since I have a set sitting around but want to see how a 150 pushes it first.
It has a new 40 gallon fuel tank under the deck and a custom small bow locker. Original console, minus the jockey seat. It has a nice bench seat with a lot of storage. Original arch and tow post came with the boat.
It should go live soon, I just need to install the hydraulic steering and controls. This will be in the for sale section once running.
The 6m Searider is about the same size as my last rib, the Zodiac SRMN 600, but the deck space is a lot "bigger" since it is flat from tube to tube. Once I get it on the water I will report on how it rides

I don't see any other boats in the pics, 2Rotor. Where do you hide them? :-)
Looking forward to a sea trial report.

They're out there somewhere collecting rain water That bit of orange in the 3rd pic is the Hurricane.
I got the Avon running and took it out on the bay today before the rain hits. The Honda 150 purrs and runs without any hiccups. It was owned by the state of CA and it looks like they kept in maintained. It has a stainless prop, 14.25 x 19, and I am only able to hit 5k rpms at WOT (40mph). Im going to try out a 14.25 x 17 and see if I can get the rpms closer to 5800 or 6k rpms. Anyone know if thats a good size prop to try out? The motor is on lowest hole so I will raise it and see what happens too.
As far as the ride goes...the SR6 rides similar to the SRMN 600 when hitting chop and waves. The most noticeable thing so far is that the SR6 hull has a deeper V, so in aggressive turns it leans a lot more than the SRMN. I felt like I was going to flip the boat but it just gripped the water and hugged the turn.
When stopped, the SRMN is definitely more stable, as it was almost impossible to rock it side to side since the tubes rested in the water. The SR6 tubes are a few inches from the water so the boat has some room to roll just a few degrees before "bottoming out." I feel like its a great hull in the 20' range.
I will report back once I get the prop dialed in and the rigging cleaned up.

Saving up for either a 600 SRMN or 6m searider, which do you prefer? In BC and out in rough weather a lot so I like the deeper V of the searider...
Though I'm sure either will be a nice upgrade from my SIB

I haven't had too much time behind the wheel on this Searider yet but I feel it would do better in rougher water as its a heavier and deeper hull. Someone correct me if I am wrong but I think the SR6 is almost twice as heavy. On the other hand, the SRMN was very fuel efficient and did not need a lot of power to make it go. I don't think you could go wrong with either one. The SRMN handled the rough stuff really well.
How is the market for used larger RIBS in Canada, do you see them for sale often? I had to wait a while before finding a SR6 for sale. I think there is another one for sale in the US right now too. I don't think I have seen any used SRMN 600s for sale lately. Btw, I should have my Hurricane 630 on the market soon too. Good luck on your next purchase.

The Searider is generally more stable at rest due to the flooding hull. I do believe you are correct that it is a heavier boat. They are built like tanks.

Avon Searider 6.0 project
OK I finally got the rpm/speed issue straightened out. Being a boat newb, I didn't realize how much a dirty hull can affect performance. I cleaned the hull and WOT is now at 5800 rpm, 49 mph GPS, 2 people and 35 gallons of fuel. Those numbers seem a bit too efficient so Im guessing the tach or gps may be off a bit. Either way, I think the motor can be raised up another hole so lets see if I can squeeze out a little more from the setup.

Assuming you ran for a good stretch your GPS can't really be off. If you only did say 400m then its possible to say you did 600m (although darned unlucky to get a -100m error at the start and a +100m at the end). Most people with modern GPS are getting accuracy of single figure metres. So over 400m worst case it says you did 420m... So 5% error max.

Went and scanned the motor today. I think I put on at least 50% of the WOT hours on it in the last few weeks. The new owner should be on his way down to me any day now so I will try not to add anymore WOT time *evil grin*
If anyone out there is looking to power an SR6, I think a 150 is perfect. With four guys up, I was still hitting 45+ mph.

Hi,
Just waiting to get my SR6 tomorrow with new engine on. It's a Suzuki DF140 BTGX, but I have no idea what Prop would fit the best.
The boat has 730 kg without fuel and crew after big refit. Maybe we used a little too much epoxy...
But back to my question, what Prop do you use on your SR6 with the 150hp?

Nice project!
I am about to order an engine for my SRMN600. Not much experience with those hulls here, may I ask what you had on the back and did that feel sufficiënt?

A little disappointed
Hey,
after some trouble with the engines certificate, it took some more time, to get the boat on the water...
But finally I had it out to the fjord the first hours this week, to drive in the new engine. In the end of the trip, we dared to wot, but it just made like 34kn.
That was a bit disappointing, but the engine spray's a lot of motor, so I think we will take it up one hole, and maybe try another prop. The engine reached easily 6.3k RPM, so it could be a bit bigger I guess.

Just to finish that point...
I have the boat in the water now and we did the first try. Its a pity to see the engine is too low, so water spraying too much while driving and trimming too high. Also we will change the prop now to pitch 19", next to take the engine one whole higher...
