As a measure of how soft I am getting I have decided to put heating into Louisa. The plan is to fit a cheap chinesium planer heater in the engine bay, duct warm air into the cabin and take the cool air from the back of the quarter berth. The exhaust will route through to a transom stern gland.
The heater is bought and onboard, slightly disappointed that I selected the heater for it's simple controller and a more complicated one arrived. I have opened the cockpit sole hatch up so access is good. The route for the warm air duct isn't straight forward but it looks like I can lead the duct through the locker under the quarter berth, only 4 off 60mm holes to drill! The exhaust pipe only needs to go through the aft bulkhead in the engine bay but considerations around heat are a worry. I have made up a bracket to support the heater and ordered the extra ducting and exhaust pipe.
Next stage is to drill holes, some big holes and probably 10 of them!
Initial install went well apart from a couple of minor problems. A hole in the wrong place and several broken drill bits but the main system is in and working. It took a while for diesel to make its way through to the heater and the transom outlet hasn't been fitted yet.
