Putting Our Stamp on TTR ~ Part II
Our previous post concerning customizations for TTR seemed to be well received; so we will go forward with “Our Stamp, Part II”. Please remember that the decisions and changes we have made are not necessarily right, wrong, or suitable for everyone; they simply reflect our preferences. These aren’t necessarily the most exciting topics, but they are important when planning to live on a sailboat.
Dinghy davits – As much as we loved Let It Be, one of the Helia’s weakest features is inadequate dinghy davits. Frank and I removed the dinghy engine for any overnight passage and the dinghy remained a matter of concern on passages.
Improving on the dinghy davits seen on previous HH Catamarans was well spelled out in our contract for TTR. The redesigned davits in addition to carrying a sufficient load with a big safety margin would have to meet the following criteria 1. With the engine down, the bottom of the shaft had to be 38 inches off the water 2. Both davits had to touch the port and starboard inflatable tubes of the RIB for stability 3. The dinghy had to sit level from side to side when fully lifted into the davits 4. The stern of the dinghy had to be lower than the bow to allow water drainage.

Combining the design skills of Gino Morelli and James Hakes with HYM’s fabrication capabilities, dinghy davits have been created that are both esthetic and functional. The design and fabrication of the first set of davits was finished in time for installation on Utopia, HH55-04, which arrived in Newport, RI last week. The reports so far are very good. Many thanks to those involved, we look forward to a happy and stable dinghy.
Solar MPPT controllers – HH offers several solar package options and all HH solar installations include Solbian SP flex panels fabricated in Italy using ultra-efficient monocrystalline Sunpower cells and installed on the coachroof of the boat. HH’s standard install involves wiring 2 of these super expensive 12v panels in series to one 24v MPPT controller to charge the 24v house bank. All this makes sense except when confronting the shading issue which is inevitable in all boat applications. When only 2 of the total 72 cells (36 cells each panel) on these 2 series wired panels becomes hard shaded, the charging output drops by 60% or more. Genasun boost controllers to the rescue! TTR will have 1 Genasun MPPT boost controller for each panel boosting the charging voltage from 12 to 24v. Therefore, if 2 cells on any panel become hard shaded the loss will be only the output from that one panel not two panels. I know this all seems like a lot of mathematical gooble-dee-goop but that’s what my man does well! We are hoping that our solar charging will reduce generator run time to only 4 hours every third day at anchor. Thank you to Jessica Li, the HH electrical install team, and the onsite supervision squad for helping us to make this happen.

Folding propellers – HH offers a Gori 3 blade folding propeller as it’s standard; it’s shiny and beautiful. Nevertheless when researching folding props for Let It Be; we were overwhelmingly led to the Flexofold 3 blade folding prop and specified the same for Ticket to Ride. Yachting World Magazine performed the most objective testing of folding and feathering props and published the results in their March 2015 issue. These tests showed the Flexofold prop was the top performer in all categories including forward and reverse thrust, top speed, low side force, and low drag when folded. The Flexofold prop has an inexpensive off the shelf hub anode in comparison to Gori’s expensive proprietary anode. The Flexofold is simple and maintenance free without the gimmicky overdrive feature touted by Gori. And last but not least we were incredibly happy with the service provided by our Flexofold props on Let It Be. We could see no reason to change from what was working.

Antifouling Paint – During our 5 years owning Let It Be, we had antifouling paint applied 5 times. Three different paint brands, 3 different boatyards, 3 different islands and all the bottom paint work (sanding, preparation, application) for better or worse was performed by the boatyard. The paints ranged from Sherwin Williams (least expensive) to Sea Hawk Islands 44 (most expensive). Regardless, none of the bottom jobs looked satisfactory at 10 months much less 12; very disappointing. While living on LIB a bottom job cost $5000-7000, required planning, involves some risk for the boat, and moved us off for at least a week. Our cost involved haul, launch, blocking, paint, labor, yard days, lodging for us off the boat, kennel time for Captain, and eating out. We figured there has to be a better way. TTR will have CopperCoat brand epoxy paint applied to her clean hull undersides under the supervision of the Chinese Coppercoat rep and we hope to get 5 years out of CopperCoat. CopperCoat will add about 100 pounds, cost maybe 25% more, and only comes in a brownish/tan color that will patina into a blackish/green color; however, it could save us mucho dinero, is much more environmentally friendly, and could remove the hassle of annual bottom jobs.

Yes, HYM really has worked with us to deliver a boat that meets our needs, plans, and expectations. I have saved the major interior customizations for a later blog when I will have pictures from TTR. I think the interior changes are as exciting and important as the outside changes that have now been discussed.
