Hi Alin;

We have also looked for a while for a solution that does not include the Arch. We also intend on switching to Lithium batteries when our current Gel setup needs replacing in 2-3 years. So, we are making all upgrades that become necessary prior to the installation of the lithiums,. Our design concept is one that will be installed in stages but engineered for the final design. For example, our inverter gave out last season, so we are looking at installing the Victron 8000/220A Inverter/charger.

After many years of looking and analyzing, we have almost settled on a hardtop over the cockpit area. Solbian factory has designed the max wattage for the area, design, shading, etc. and has come up with about 900 Watts of deck mounted, flexible and walk on cells.

Our calculations show that after completion of the final concept and installation of the lithium batteries, we should be able to run the entire 24V and 220V systems on board (Not Simultaneously) on batteries and depending on sun conditions, minimal generator usage. We currently do not have solar and we have to run the generator twice per day at anchor.

This is a more costly approach than the Arch, but like you, we like the lines of 54 and wanted a complementary design that did not take away from her sleek lines.

Happy Sailing;
