I have a Bandit 18ft trailer sailer. My friend built it in the 1980's as a micro cupper racing cruiser. I have now aquired and have done a small amount of work to get it ready for sailing. It has an adjustable outboard mounting on the back.
I am going to buy a second hand engine and I think I want to buy a 4 or 5 hp 4 stroke mariner sailmate. They have an integral fuel tank and the option to attach an external tank. It has a low pitch,and larger diameter prop which should allow higher revs and therefore stronger thrust??? With a displacement hull. It will normally have a charging circuit in built as standard. Also the forward neutral and reverse controls are on the tiller making it more not controllable for my wife ( me to I guess) if we go through locks on our local river.
I have researched this and many other forums and the internet generally but I can't find the answer to 2 questions and I am now seeking the help of this forum. Than you in advance:
1. If I am faced with a headwind and going against a fast running tide and the engine is already running at a high throttle opening because of the low pitch prop I will not have any reserve power? Wouldn't it be better to have a normal prop that Normally pushes the boat at say 5 knots (max i understand for that length of displacement hull) running at half throttle but when it is slowed down by the headwind etc I will have reserve power in the engine to push the boat upto max hull spread again.?
2. How does one know if sailing boat has a displacement hull. It's a microcupper/micro tonner design intended for racing. Would that go faster than 5 knots or even plane if it had a very big motor (I am not intending to do that but I have no idea what make a hull a displacing hull. And I have seen the macgregor sailing boats plane.?????
Thank you bremar.
