Ocracoke 20 in OZ

Recommended Posts

Broken windsurfing masts (scavenged from shops for free) have been so useful for me over the years.

Have used them for dingy masts, booms, support posts, outrigger and VHF aerial bases and now bulkhead penetrations.

Ready made carbon fibre tubing - and having a tapered shape - there is always a section which is the perfect diameter for a particular job.

Hoping to have the decks down this week.

Seems to be endless opinions on aluminium fuel tank installation.

I have just tried to eliminate the possibility of water trapped between the tank and another surface.  

Have gone with twin tanks so I can play with boat trim.

Have managed to route the tubing without need to cut into any longitudinal stringers.

Motor wiring and hydraulic steering lines will be up underneath the starboard gunnel for access purposes.

Depth sounder (transducer) cable will be port side to avoid 'noise' interference from other wiring.

Slight deviation from the plans from now as I require an elevated deck for fly fishing.

Front deck has a freeboard around ankle height and lower one just above knees (for rougher water) - perfect.

Went with a H90 20mm foam to try and gain some weight back due to the modifications.

Deck panels were vacuum bagged on a piece of 30mm MDF board/table and beams using cryovac bag rolls.

Thanks Riggs.   You must be getting close to finishing yours?

 

I am relieved to get the anchor locker finished..

Very confined space with lots of tight corners.

I know 3 coats of epoxy is good enough but I can't help myself - ended up filleting, glassing and flow coating the lot.

 

Also created some solid glass sections in the gunnels for the fuel filler and flush rod holders.

Im thinking this will save the hassle of needing to seal edges of ply after holesawing.

 

One of the constraints for my project is the request for a head/toilet from the wife.

Not so easy on a 20 footer as a console could get so big it detracts from the appearance of the boat.

I have come up with low profile design (43" above deck) but leaves enough head high to squeeze into when you step down into the hull.

I hope it looks ok on the boat..

Great work Lenm and nice looking console !

Karnic 1851 boats have a center console that can easily accommodate a person under it when opened from the front side . Maybe you can do some google search about it. The front seat of the console can be opened forward with part of the flooring with it

Currently adding foam to the stern sides for 'level' floatation certification.

Can fit quite a large amount under the wide gunnels.

A bit unfortunate about the lost storage space, however i've always been one of those paranoid captains..

@lenm Amazing work! It looks just like my Jessy 15' except yours is larger, more complex, prettier and it has a person building it who knows what they are doing.  ??

 

Thanks Justin !

 

Have loved checking out your progress too - the Jessy and Marissa are nice looking designs too.

 

Like you I chose a design based on building space and time available to me.

 

Incidentally, this project was meat to be an 'test run' prior to building a larger boat (40' sailing catamaran) sometime in the future.

Something to explore the western pacific when I retire from work.

Considering how much time and energy has gone into this project, I am realising I don't think I can pull off building something over twice the size - single handed.

Plus, my wife would leave me for sure ?

Depends on what your motive is?  Just kidding!

 

Interestingly, the boat you are building was one of the boats that drew me to boat building.  I decided on this also as a bit of a test run, however, I simply do not have space for anything larger than what can fit into a standard garage. 

 

You will still have the satisfaction of building a boat and the knowledge will not be lost.  God know about the maintenance requirement of these things!

Finally got the console installed today.

Also added a level 'pad' for electric trolling motor.

 

Starting to think about rub rails now but can't decide on best material to use for the base.

I can't help but think with all the self tapping screws (required to affix the stainless rails) might create problem of water intrusion (timber rail) or not enough screw holding power (foam rail)?

Please any suggestions appreciated.

Thanks Justin!

 

Started piecing together the inside of the console.

The whole thing turned out so lightweight using 20mm foam and a single layer of 1700.

 

I know its only a 20footer but might try and squeeze in a 'low profile' upper station as well.

I.e. stand on top of console / through hardtop.

Good for spotting fish on the flats on calm days..

Strangely, all of a sudden it feels like I can see the light at the end of the tunnel.

Its amazing how a few solid (uninterrupted) days can make big difference to progress.

 

Console is finished Inc toilet.

 

Not sure whether the design was intended to have scuppers?

I have added some in any case. 

If they are too low I will just close them off and open them for hosing down the boat only.

 

I don't trust engine installers so have pre-drilled the transom myself using a borrowed template.

The oversize holes have been backfilled with epoxy and CF chop strand and will now be glassed over and re-drilled smaller to eliminate any possibility of water intrusion.

I have no doubt engine installer would have just pumped a heap of 5200 in there without sealing any timber end grain..

 

Salvaged a nice teak and alloy steering wheel of a classic car - which I will make fit to the hydraulic unit somehow.
