Humber Ex Rescue Boat
Hi again guys, just looking for some more info. I have done a search but not come up with anything.
I've been looking at a little Humber (approx 4m ish) with a soft bottom, (SIB?) for sale locally. The tubes do need a little attention as one is definitely punctured somewhere (little hole, can hear a hiss if I lean on the tube) and the other is softer than I like after a couple of days. It used to be a rescue boat but the decals have been removed and it has a Mariner 40 2 stroke on the back, advertised as Ex-RNLI.
Firstly, is there a big difference between a soft bottom and a rigid hull when it comes to choppy seas? Does the keel have to be inflated, because I could not see anywhere to do that. She has a carpeted ply deck with a console mounted and a small dodger in the bows and the cross beam there has separated from the deck at that point. Would it be a matter of just re fixing that, or could it be an indicator of a larger problem?
I was thinking of fitting a Mercury 25hp Bigfoot 4 stroke and I assume that this would still push her along well, as I have someone who is looking for a 40hp engine. However, if I keep the 40, do I have to mix the fuel or is there an integral oil reservoir which you just need to top up every so often?
I know I am asking a lot of questions, but I've never used a soft bottom boat with a 2 stroke before.
Lastly, what about launching and retrieving, is there any special way of doing this or a special trailer you need. I'm just wondering as there is no solid keel to go on rollers and if bunks were used, they'd have to support the tubes, right?
Thanks for all your help guys, sorry the post is a bit long.
