Love Ritchie Compasses!!!  But then, I like compasses period.  Chittiest, nastiest day, raining like hell, visibility almost 0, hold one in your hand, you know which way you're going.  Hold a GPS/Chartplotter in your hand with no power, you have a paper weight...

All my boats have a compass at each helm station.  What you said - when everything else goes wrong, Earth's magnetic pole remains...

The very first purchase for any boat...from kayak to supertanker...should be a good, reliable, mechanical compass.

In our age of I Phones, I Pads, GPS apps on this and that...some may think a real compass is unnecessary.

That is...until your service has failed, the server is down, the boat's main has shorted, you're way offshore, and the fog rolls in...and you have NO CLUE which way to run a reciprocal compass heading...

Because you have no compass.

BTW Scotty, I know you have the transom boxes, most likely one of them being plumbed for a livewell.  You also have a livewell in the leaning post, correct?  So my thoughts are to have 2 pickups, with the 800 GPH Rule Tournaments I have mounted atop the shut-off valves (yes, well put elbows on the pickups to orient them horizontally), both pumps are dual port, so we can feed the washdown pump from one of the Rules.  Shur-Flo or Jabsco for the washdown pump.

Groco or Conbraco bronze high speed pickups, same makes (or Apollo) for the shut-off valves...

Yo bro,

The transom boxes are not plumbed. They are for dry storage, bow lift, and old-school aesthetics. Want to keep them dry as possible for buoyancy in this application. They have drains installed, plugs removed while on the lift.

They have a moderately pronounced downward hook....designed to function as fixed tabs, providing bow lift. They are pretty amazing...Farl's boat gets up and goes real quick due to lift from the boxes.

Installed already on my mess is a 3/4 bronze Perko clamshell pickup and thruhull with Perko seacock above..feeding two pumps. Needs fine tuning  though...not exactly all-in on the engineering...we'll talk it over.

Here is a discussion from about a year ago on livewell rigging:

That's cool Scott.  The Rule pumps are dual-port, so the lower port acts as the pickup for a second pump (usually washdown), the upper port feeding the livewell.  And no, the livewell pump does not need to be running for it to feed the washdown pump...

Ok, so I hesitate to even ask this for fear of reprisal   :pirat: , but how does a moderately pronounced downward hook provide additional bowlift?    I can understand how the additional surface area provides a corresponding increase in lift to help it get on plane quicker during acceleration, but unless I'm crazy-stupid, once on plane wouldn't the hook actually function to keep the bow down?

...and btw - this boat rigging think-tank, brainstorming, pow-wow thing you got going is the chit!! Talk about some well-informed and insightful decision making!  Can not WAIT for the daily engine overhaul and rigging updates once she get's down here.

Ryan, I think Scott meant stern lift...basically working as fixed trim tabs.  Just a s one may drop the tabs when getting out of the hole to get on plane quicker, helps pop the bow over the wall...

[gran398]

Thanks Ryan!

You know...good question. Fitz says the boat planes faster with the boxes. Or maybe I misunderstood. Bob is a whole lot more knowledgeable on that than I am. His idea makes sense.  Anyway...they look pretty cool

Farl, can you input...tx!

[seabob4]

The bow, by it's design as well as the incorporation of lifting strakes just aft, has it's own lift.  But when accelerated, a boat's stern squats, and she has trouble getting over the hump, as the stern is trying to push it's way through that wall of water.  Provide stern lift at the same time the bow is providing lift, and, viola, over the hump quicker...

Can you smell it?

Coming to a Weeki Wachee abode soon!!

Scott, this is a good read from Bennett that basically explains your boxes and how they work as trim tabs... http://www.bennetttrimtabs.com/guidetotrimtabs2.php

Nice day down here, huh Nando?  Yccchh!!

Well at least well get some lower temps in the evenings.

I've run 22-2's 12 degree bottoms with and without boxes and they make a big difference. Scotty meant to say stern lift. With twin 115's at around 750# the boat will plane at 19 mph @2950 rpms and I'm positive the boxes are really giving me some stern lift to plane at those numbers. What is interesting to me is that AS must have done a fair amount of experimenting to get the downward angle right to give enough stern lift without having her plow at high speed. I actually wish I could get the bow down even further to get a better ride in a 2' chop.

[gran398]

Thanks Farl. I knew it must've been something like that, but when you 'splained it to me, there may have been a slight chance that alcohol was involved in my interperterashion
