There ae numerous range-finder devices available for hunters using optical or simple mechanical techniques.
The simplest is inspired by the golf range finder. A viewer/telescope has several images of a golf flag in a variety of sizes. You hold the image over the target flag and when it matches, you have the range. (Our golfing members can probably give a more accurate price but I think these are around $20.) There is a sniper scope that uses the same technique but with dots that represent the size of an average human head. Since there is usualy at least one human head visible on a boat this method would work well enough for calculating boat ranges like 150'.
If anybody wants to try marketing such a device I relinquish any claims for intellectual rights!
