| Original manufacture info says they are ok and can take an outboard upto around 80-90hp and they have a good planing hull. But bear in mind these boats are 30-40 years old now so make doubley sure the transom is strong enough to take a larger outboard as they are prone to get weak from the wood rotting which is sandwiched between the grp. |

We have recently purchased a Norman 20 with a Yamaha 30hp two stroke engine. We use the boat for coastal fishing and pleasure trips off the Devon coast, we have found it to be a very sturdy and capable boat.
The last two owners also used it off shore and never had any problems with it.
The 30hp engine is a very good runner but it is old, we feel it is a little under powered and it struggles when the weather gets rough, so for peace of mind and safety we are looking at fitting a 40hp or 50hp.
I hope this helps.
Cheers

Yes, but that is only the technical answer, there are many other questions that need to be answered before you set off.
Is a 1930's biplane capable of flying across the channel? - Yes, but that is not the whole picture.
Is a model T Ford capable of driving coast to coast across America? - Yes, but that is not the whole picture.
See what I mean???

| We also have a Norman 20 with a suzuki 50hp 2 stroke. Would also like to take it on the open sea, though local boat yards says these are not designed for open seas and would certainly need a calm sea!...my only concern is fuel...we have only pottered in ours and we certainly seem to use an awful lot of fuel....soes anyone know the average "m.p.g" for this type of engine? |

Boats are usually quoted as "Gallons per Hour" or "Liters per Hour" in new money.
When at sea or even on a river the distance traveled in a certain time will not be the same twice. Either due to tides or currents helping you along, or pushing you back.
What is important is knowing how much fuel you will need to complete the trip. Most coastal boaters will factor in a reserve of around 25% for safety.
Although rumors exist on the internet about me running out of fuel at sea, they are entirely unfounded. Although I did run out on one engine around the Lazy Otter (Lumpy Oyster) on the Old West last year which was almost as scary as running out at sea.
Fuel consumption of large 2 stroke outboards can be astonishing and will be 10 times what they achieve at pottering speeds when running at full chat on the plane.

| Thanks all so much, yes thats about what we achieve "per hour", the reason i asked was because i wanted to do "something" in my old age, the "something" being travel from Littlehampton around the coast and up the Thames to our daughter in Putney....I fear to achieve this will need me towing a petrol tanker behind me....mind you as Del boys says "he who dares"!!! |

| Oh thats billiant!, my everlasting memory is of Delboy asking the oil-rig worker "excuse me john, which way is Holland"....We have taken a little more care, Reeds Nautical Almanac is a bible, with plans to stop at certain points to refuel etc....by the way, has anyone out there done this or something similar?...any tips, refuelling marinas, etc are most welcome |

Have only done east coast between humber and walton, I would imagine south coast is much better charted, google 'crossing the thames estuary' for an excellent guide to the thames entrance, I trust you know the rules on crossing shipping lanes and all that.
Fuel should be fairly readily available around that bit of coast but as you say reeds is the bible. (although I use imray almanac)

From Littlehampton your first possible fuel stop would be to pop in at Shoreham, then Brighton, and Newhaven. Then you've got a longish run for an outboard around Beachy and past Eastbourne to Pevensey Marina. Better load up a raft of jerry cans then because from Pevensey the next place is Rye, then Folkestone followed by Dover.
From Dover next is Ramsgate (most of the local boats are beach-boats which ought to tell you something)then Broadstairs and Margate. Then it's Herne Bay and Whitstable before you can duck into the Queenborough channel and cut across to the Medway. After that you're almost on the Thames.
Frankly - diesel boats have an easy time of it around the South Coast but like everywhere else petrol is in short supply apart from garages ashore and you need a harbour to get into to moor up safely while you go for a 3 mile hike! I'd stick the thing on a trailer and tow it round! Get the tide against you at Allhallows and you'll burn up a tank of fuel going nowhere much.
Your outboard-powered 20 would be better used going west to the Solent maybe? You've got Chi and Langstone to hide in if it goes pear-shaped, or Bembridge or Fishbourne or the Medina on the Island.
Stay safe friend!
However - as far as sea-keeping qualities are concerned the 20 is an admirable hull, I personally had one I ran out of Langstone to Bembridge to my parents who lived on the harbour there and I used it in some pretty foul conditions too BUT it had a 1600cc Ford Crossflow with an Enfield leg and was pretty quick and capable without costing a bomb in fuel.
The cost of boating is insignificant compared to costs of a young wife and two teenage kids! |
