Well Paul, there are five errors in your last post…. Spot the mistake time?
With regard to boat sizes, a 4 ft cabin cruiser will have a beam of around 14 inches and that will simply be too big for many people to find room to construct, transport and store it easily. Wives don't usually take kindly to something like a Sea Queen as the lounge centrepiece. By all means offer a 4 ft option but make the 3 ft one the main marketing focus I would suggest.
As far as proof reading is concerned, it's not really a case of getting better educated contributors. You do sometimes get the situation where someone has submitted wonderful material but lacks the writing skills to get it down properly on paper and the content has to be extensively reworked, but that is the exception rather than the rule.
Most proof reading is concerned with more mundane matters. Sentences which go on too long and have to be chopped in half with a full stop. Instances where the author has made assumptions about what the reader will already know which are not necessarily the case and which need a bit of extra explanation added. Adjectives which are repeated too often when alternative words will make the article read better. Too much use of 'also' and 'and' where the writer has had an afterthought and just stuck it on the end of a sentence like an unwanted appendage.
And then there are the cases where a wrong but similar word is used: principle/principal; affect/effect; complimentary/complementary; phased/fazed etc.
Most difficult of all to pick up are the minor spelling and grammatical errors: 'it's' instead of 'its'; 'to' instead of 'too'; missing apostrophes; inappropriate capitalisation and the like. The issue here is that when you re read something you have written your brain sees what you expect to be there rather than what is actually in front of you and this is a real problem. I try to get over it by printing out what is on the computer screen and reading that instead or getting my wife to check for common errors although she can't be expected to pick up the technical stuff. When reading other people's contributions, most of these errors jump out at me first time around but if I miss any then I'm not so likely to see them next time I check because I am already familiar with the subject matter.
Here endeth today's lesson.
