December through January Write up

The guys at RMI were working hard during the month of December to have Nashua's hull ready in time to turn over on schedule in early January.  The hull was successfully cold molded using the vacuum bag technique, which minimizes the amount of glue needed for bonding the laminates to the hull planking keeping weight down dramatically.  After that, a final layer of Fir planking was added fore and aft to hide the diagonal laminates and to create a stiff and more durable outer layer.

One thing we all take for granted during this stage is how much work goes into fairing the hull before painting.  The goal is to have a bump free totally fair hull surface to allow the boat to move as quickly through the water as possible and this is all done by the grunt force of manual labor.  Using 2ft long sanding boards, workers move back and forth over the hull in a criss cross pattern to get rid of any high or low shapes in the hull.  When the hull is smooth and fair, multiple coats of an epoxy primer get applied to the hull with fairing in between.

We thought it was a good idea at this time to have RMI mold splashes from the hull shape.  These will be used as a sort of stand to support the boat in the off season and if we ever decide to ship the boat somewhere.  We took advantage of doing this while the boat was still upside down. This pushed the turn over date forward a couple days, but we will be glad we did it later on.

Terry and I drove up from Newport meeting Jeremy, Russ, and Wendy who had just flown in from California to see the boat turn and partake in some critical decision making.  It was a cold morning, with forecasts in the single digits and snow on the ground, and Nashua came out of the red RMI building just after lunch.  She was turned over in the travel lift and placed onto a trailer to be brought back inside for the first time in the upright position.  It was amazing to see the boat transform from mostly just a shape to a beautiful utilitarian object.

With the boat right side up we all go the chance to inspect the interior before any systems get installed and take note at a few items that are different with this boat then we saw on Equus, mostly the wooden floor structure which was an added bronze feature on Equus.

Now, it is a new year and there is a lot to look forward to.  Soon, we will see the interior of Nashua come together as deck beams get installed and systems are put into place.




December through January Photos

The cold molding laminating begins.  1/8" cedar laminates are glued on in diagonal strips



Once all the laminates are on, glue is applied between the laminates and the existing hull then air tight sealed in plastic.  A vacuum is hooked up to the "bag" and sucks all the air out and creates enough compression to squeeze any extra glue out to create a perfect gluing surface



A final layer of fore and aft planking goes on



And gets faired down



Here the teak transom laminate is being attached




Once the boat is completely fair, it is coated with a epoxy primer, which then gets faired even further



January 9th, hull turning day.  Terry inspects the splashes that were molded to Nashua's hull that will be used to support then boat during storage



John shows off the interior of the boat before it is flipped



The stem sticks up from the bow.  This will get trimmed to fit later



A nice look at the beautiful forestay chainplate installation



Ready to be flipped!



The boat is pulled outside on rollers and placed in the travel lift.  One strap goes up and the other goes down and turn she does!



A hydraulic trailer is needed to take her off the straps and bring her inside right side up



A view of the hull from inside the office



The team meeting with RMI after the flip to discuss some crucial details



A closer inspection is made of the interior now that she is right side up



A detail of the stem and anchor locker



All that is needed here is a wheel!



One nice feature that Equus didn't have are these beautiful floors




One final view



A deck beam gets installed midships



Looking aft, another deck beam is installed



This is the area the engine will sit in with the engine bed mocked up in pencil lower right
