Hopefully we splash on Monday. Yes, that is a custom Carbon Tiller and traveler bridge.... all created by Andrew Berge... the Kiwi of Northern Michigan... father of Norm Berge (Denali, Flash Gordon, etc)

Looks GREAT! Though with Andrew working on it, and hopefully Ken as well, I would expect nothing but the BEST from those two when it comes to boat work. Big thumbs up!

Never mind. I see from the other thread you installed an inboard. What kind of engine? Best Olson redo I've seen to date.

#212 is an inboard from birth. BMW was the original, the previous owner replaced that with a Yanmar.

 

We are the 2nd owners of this boat.

I'd like to know how your backstay is rigged.

Back stay is below deck, comes up through the middle box. Mounts the same on the port side, then shoots down below on starboard.

Looks great, why didn't you go with athwartship sheeting for your jibs?

The Jib tracks were moved outboard.... Genoa tracks were shortened and moved aft.

If the same level of craftsmanship has been applied to the internals (BOD etc) then this is the sexiest O30 going around. Love the work gentlemen.

Get rid of tracks altogether and replace with floating block and soft pad eyes, etc. Saves even more weight. Spoke with Andrew and Ken yesterday and they are liking how this project came out. GREAT update and remodel to you!

Looks like your rating took a hit from the mods, hope it wasn't too bad!

 

Weight difference was 15-20lbs. No hit on ORR or LMPHRF.

It's really sweet, all of it. Curious about a couple of things. How deep is the cockpit floor? Do your feet touch when you sit on the rail? Were there any pipe berths before the mod?

Pipe berths are original will be installed before the weekend. they are mesh type fab with an aluminium tube and will but to that bulkhead you see in the backstay pic. I will tell you that there will be more head room to get in and out of the Olson pipes...lol... for any olson'er that has gotten in one.

 

The center box is also the skippers' foot rest and I believe he'll be able to use it while leaning back on the life lines. Not sure the total depth... we splash at 4-5pm today and it's also race night....

What is the functional advantage of the open stern?

 

Have you ever been on an Olson 30? This wasn't done JUST for the open stern.... it was done to make the boat more functional. Instead of 22inches of room (with seats on each side of you) in the pit.... there is now 44 inches and no cumbersome seats to put you off balance.

 

Here is some more functional additions...

 

* Below deck backstay with center console cleat (easier to use, less line on deck).

* Primary winches are now level and in a great spot for trimming. (those that sail olsons will testify the handstands needed to grind on the lowside with the stock mount)

* More room for crew and crew weight shifting. (getting weight in the back while in planing conditions was a task in itself, but if you had to jibe having crew behind the skipper was a pain in the ass.)

*Diesel fill.... the tank fill is now on the center console as to reduce spillage.

*the Engine gauges are in a spot for the driver to monitor

*the kill/choke and throttle are now on the port side, in bedded as to reduce snagging of lines.

 

 

 

Overall, it was a 31 yr old deck with some soft spots that need to be replaced... Andrew's suggestions and his ability to take our feedback of 'what would be functional' made this boat what it is. The goal wasn't to change the performance of the boat... the goal was to make one of the greatest sailboats of all time.... a bit more fun to sail.

 

I hope we will have accomplished that.

Rum,

Why did you keep the MOB pole tube? Great boat. I race against one and she is great to watch ghosting over the water.

Looks great! Also noticed the toe rail gone. Please post a few racing shots. Any rating hit with the mods? In the Chesapeake, I believe I would have taken a hit for the potential for performance improvement and possibly displacement reduction.

Yes the Stability mod is still on the keel.

 

Little to no weight difference on mod(approx 20lbs different)= no PHRF or ORR adjustment

 

Left the MOB hole as it wasn't part of the mod... plus we use it in the mac... for the MOB pole :)

 

Toe Rail was left forward of the stays... (twings still connect to it, Bungy for sails, etc.

 

The trigger for the mod was a soft spot around the gas fill. Then the conversation was about the 30yr old deck... then it turned to what if's.... the what ifs turned into a plan, the plan was executed and designed by Andrew Berge, who used our feed back about functionality of crew work vs deck placement of winches, etc. The whole thing came together quite well.

 

Bruce (father and owner) spent a lot of time working with and being 'hands on' as much as Andrew would let him...lol.

 

Overall the Mod is working as planned. As the trimmer, I can now have a partner to work side by side... this is immensely helpful in roundings, high wind tacks and even weight placement.

 

Our first regatta (Pics above), we didn't perform to our liking... the rig tune was off, the boat just splashed 3 days earlier and the only warmup sail we got was a friday night sunsetter in light winds. The rust is off now and the next 2 big regattas are the Chi-mac and Ugotta... Which I hear is back to 2 days of "tour da bay" racing.

I cannot remember seeing any Olsen 30s with an inboard engine. Are there very many of those around?

 

#212 was picked up from the factory as an inboard. There are very few left as they've been converted after the BMW engines died out.... this one has a yanmar. (We are the 2nd owner)

Long ago there was an O30 in Marina del Rey that had been modded with an air cooled inboard! Sold by Brown Marine Engineering in Lawndale, CA. It was a marinized 10hp Tecumseh with a water jacketed exhaust; very light and noisy, but a feature was the helmsman could attach a dryer hose to the cooling air exhaust outlet in the cockpit, shove it up his foulies and get dried out and toasty.

 

The owner was a bit odd (might have been Mr. Brown himself, can't remember); he would have 7 crew show up at the boat and send up to 5 of them home depending on wind conditions. I was one of the second stringers, unfortunately, so my relationship with the boat was brief.

Contender, once on Lake Ontario then NYC area had the Brown inboard. It was great...prop shaft had a minimal angle so it was almost in the turbulant layer, with minimal drag. We had a 6 second bonus but sailed even with the OB boats. We sailed level in OD events, and did well, but killed in PHRF events.

There's a light blue one in Alameda with a factory inboard. Does some of the beercan series. Boat is sailed with some special need kids so it is not hard raced.

Yes, it was a great concept. Perfect for maneuvering to the start line from and to the dock, not so good for 150 mile overnight deliveries to or from a venue. I mean, it's a lawnmower engine; do you run your lawnmower engine continuously for 24 hours?

First big wind test Monday of the Chi/Mac.... 20-25 from the stern with 4ft+waves (swear there were some 8s in there). The efficiency was amazing. We moved crew back and forth for jibes, sail changes and weight distribution with ease. The helmsman wasn't affected at all by this.... and it was much easier to drive in the blow and waves.

 

14.6 with the chicken chute was my speed record for the day... though we had several 14 sightings and many sustained 12-13kt runs when we were able to catch 4-5 waves in a row.

We were rafted up next to Spar Wars after the Chi-Mac, and the O30 was gorgeous, looked like a brand new boat. But I didn't know Andrew Berge did the work. I had the good fortune to sail with Andrew for a regatta and I have seen some of his work (a custom carbon piece for our boat). He's a first rate guy, great sailor, and he can't do other than first rate work - there's no such thing as "good enough" for him.

You should contact John Fries about turboing the Main. I got a longer boom built by Bellengier and a bigger boom to help add some more horsepower because of the turbo keel my boat had....

great story! this is the brown marine engine in hull# 108. not too many of them left i don't think. it's a pretty well engineered setup. hilariously for a boat from the great white north, it's actually a snowblower engine for the power unit. exhaust is well done, has a secondary water pump for this, electric start, morse controls. it was well thought out, not a jury-rig. have lots more photos if anyone wants to see them, i can send link by pm.

Never sailed an O30 but from the pics they look fast- which is as important as actually being fast!

I had the abovementioned gas inboard in my Olson 29. Even though well insulated, it was LOUD. Didn't weigh much and strut/prop created minimal drag so easily worth the 6 sec/mile standard PHRF credit normally proffered.

Other primary disadvantage was the valuable space it took below by occupying entire area between the quarterberths. I did a lot of long distance racing and opening that area back up made live aboard so much more convenient.

The beauty of the Olsons is their simplicity. Stay with a small outboard and don't muck it up.

Yea, KISS.

 

I'd like to see the OB toward the front of the cockpit with the well / plug type arrangement. I don't know what they call that but when the seas kick up no more cavitation when the stern lifts, plus you can probably go with a short shaft and lower HP OB.

Clean... but not One Design legal anymore?

 

 

The weight was not changed (-/+20lbs). However, SparWars is an inboard.... most OD events are all OB.

 

I just saw a new mod come out in Cali.... +300lbs! I don't think that one is OD anymore. http://www.olson30.org/projects/radical-refit-olson-30-007-the-source
