I used MDO on the jumbo for everything except the hull.   I didnt notice any more epoxy use than either fir or the wood jim sent in the kit i bought.

I have some MDO covered in glass, some eposy only, and some bare.   Anthony Lysander just finished a major house refinishing last year with a hull that was painted only and not coated with epoxy.   I have a few chips where it was paint alone.  mostly jsut that heavy craft paper.

I also saw another post, i think it was ray macke on his big 25 foot cruiser, that sanded off the craft paper for glue up of joints.

and so it goes round and round.     But, the cost difference in MDo over marine ply is about half or less where I live.     

some of use bigger fillets.   some waste more.  some less.     And some builders are floating their glass on top of too much epoxy, adding weight and cost, and no strength.       

And soem filll the weave with epoxy alone, alternatively filling and then sanding, filling and then sanding.    I did that too.   Once.

You fill the weave with thickened epoxy which goes a long way, fairs easily, and costs far less with fillers than straight epoxy.

I remember boat one dumping big pans of epoxy on top of the glass and wood... epoxy everywhere.    Renn would be absolutely screaming!!!!

I was thinking "epoxy is good, so lots of epoxy must be great!"      In the end, I spilled and wasted a lot of epoxy.   

Renns way is to always have something set out in case you have a little extra.  I dont work that far forward.  In fact, I dont work more forward than maybe 30 mins except one time when we had a week to knock out a hull and then we applied some brainpower to it.  it worked too

So I am sure twin 70's 4s or twin 60 etec would push the boat at a good 10-12 mph on a single.

Main concern is would twin 60hp etec cruise at 22 mph at 2/3 throttle?
                      would twin 70hp Yamaha cruise at 22 mph at 2/3 throttle?

10-12 mph with a single in a jumbo??/ That's a good question. I know my widebody slides onto plane so smoothly that you can actually run it with a decent attitude at 10-12 mph. I do not know about a jumbo, if it behaves the same then I would say 10-12 is probably possible with a single in that hp range.

Who has run their jumbo at 10-12 mph? is it running with a good attitude or is it trying to climb a hill onto plane?

22 mph cruise with twin 60s or 70s seems about right to me.

Thats a nice unit.  I've got one of those on my motorhome that I never use.  Thinking bout moving it to the boat.  I was looking at the fixed bars in $150.00 14000 lum range for flood lighting.

I always thought the k-bay house was rather unsightly ...but not out of place in Alaska, where many 'houses' have been invented for boats to protect the owners from the weather.  That said, I have thought very seriously about building a k-bay house widebody because it absolutely can't be beat when it comes to utility and handiness for all that you might want to do ...and the house CAN be put together to allow a couple of people to camp in it if they needed to.  It's really a good design and I'm not sure why it hasn't been more popular?


After 7 seasons I've yet to once wish I had a K-bay house vs. a cuddy and pilot house.  I think my useage runs roughly 50/50 overnight trips and day fishing trips.  I can comfortably fish four people from my fishing trip, and my kids prefer sitting on the roof of the cuddy when fishing for silvers or rock fish which expands my room to comfortably fish six people.

No matter what the weather is, somebody or several somebodies find their way into the cuddy to take a nap when under power.  So having sleeping space without having to reshuffle gear IMHO is well worth giving up the space for two people to stand and fish off the bow.  And when the weather is down right snotty, you simply can't have enough warm dry covered space in a tolman.

Going to install an LED Light Bar on forward portion of the wheel house roof.  Maybe 30" combination spot and flood.  Eyourlite has some good prices has anyone tried that brand or is there something better?

The boat to the right in this pic is a widebody with a modified K-Bay cabin.  On the left is the traditional cuddy arrangement.  GA in between the two widebodies.

Hi Dave,

I have a 23' widebody with the standard drywell setup, 90 suzuki main, and 15hp suzuki kicker.  I offset the main engine 7" and the kicker is sort of centered in the remaining space.  The main motor clears the kicker when the kicker is tilted up but they touch slightly if I then tilt they are both tilted and the 90 is turned all the way over to port.  I could easily have set the main over another inch or two to starboard and that would solve that problem.

I drilled the holes in advance of having the shop hang the motors.  Drilled oversized, filled with epoxy and then redrilled.  The shop offered to let me use their jig but I found it was pretty easy to just lay out the standard hole pattern on the transom by measuring.  They hung the motor and I did all the rigging/wiring which was not difficult, though a little fustrating dealing with all the cables, hoses, wires and trying to get them to fit through the rigging tubing and another tube where you step over them (open floor center console) - liquid dish soap was a big help for pulling cables and wires through tight spaces.

Motor is hung in the lowest setting (top mounting hole) with the AV plate a just a little higher than the hull bottom.  AV plate is a bit low (maybe 1.5 inches) as it is and I may raise it up a little this coming summe,r but I've been pretty happy with performance and fuel consumption as is so it is not a priority.

The 90 has been a great motor for this boat.  Renn initailly suggested 70 but we tend to pile lots of people, kayaks, camping gear, etc on board so went with the 90.  With the kicker (mainly for trolling) I would not want more weight back there on a widebody.  We have never been lacking for power even very heavily loaded (11 people).

I had originally planned to run twins as it seemed to make so much sense for the long trips far from port I dreamed of making in my widebody, but then economic reality hit.

For twins to be a benefit they have to be sized large enough for one to get the hull on plane, they need to have completely independent 12 VDC power systems, independent fuel systems and you need to fuel them up at different locations.  Doing twins right is several thousand more dollars than the two verses one engines to purchase, your mileage will lower with two lower ends creating drag in the water and the frictional drag of the internals, plus servicing them will be more expensive with 2X oil changes, filter changes, water pump rebuilds etc.

I'd build the 25" transom, it'll work with either 25" main or 20" twins.

To me twins start making sense on 28' and larger boats but on a tolman the added cost and weight penalty really make the single a better choice.  And modern 4s singles are incredible reliable engines.

Dave, here's the thread on the notch.  Dave Nolan did some good calcs on offset dimensions.
