Is this a sea boat or just for lake use?



I've just realised that the Great Lakes has a balsa cored hull underneath the waterline, right down to the keel.

I understand that's it's difficult enough a job to repair a soft deck, but How would you go about repairing a wet core laminate in the bottom section of the hull?

Regarding fuel consumption, here's the numbers for the famous Nelson 32' semi-displ hulls which weigh about 5-6tons depending on single/twin engines.

Surprisingly linear graph, the 6 ton version only needs 120hp to reach 15kts, but uses nearly double the hp to do 20kts at 220hp!

Regarding the graph above, and to keep the fuel consumption figures in proportion with 'real world use', I feel I must post this comment from a real Nelson owner.......

Just to add another 32' boat into the mix, the Island gypsy 32' 'gourmet cruiser'
Isn't very economical at slow speed.

The 32's speed at 2 gals/hr? About 3.5 to 5 knots. These boats are not fuel miserly vessels. They are well built (heavy) sea going boats.

For the speed range up to 16K a 32 ft Holland lobster type or similar lobster hull cruiser with single motor. At 15K you will burn some fuel but at 7-8K would be pretty good fuel burn. The down side is these boats are more toward the boat side of the boat cottage ratio so less internal volume.

So, not happy to "chug" along at six-something knots at less than two diesel-gallons an hour?

If I was happy at six K I would have kept my sail boat that powered at 7.5k with 75 Hp engine at< 1/2 throttle on a drop of fuel and sailed at 8+K burning no fuel and the ride was very good and capable of all waters and all oceans. Never even thought about the need for stabilizers with that boat. But sometimes I just need the speed.

No doubt or questioning: some people "need the speed." Not consistent with the trawler concept, but whatever gives joy.

For better or worse the trawler concept has navigated in to muddy waters. We are all aware of the haziness of the definition of trawler and more and more boats on this site and more boats defined and sold as trawlers are SD and the six and seven Knot limitation is getting rare and 10+k becoming closer to the norm. Because there is no clear cut definition of a trawler the significantly more numerous SD and planning hulls will if not already represent a majority of boats designated trawler. Just for the record my boat is not a trawler not even close and I would never try to pass it as one. Most boat sale personnel know speed sells boats (cars and airplanes) and even a few knots counts. This is why so many boats are sold over propped and set up for light boat which becomes unrealistic when a owner takes delivery and starts loading it up. I have owned many slow boats and presently own a 5.5k boat and have on order a 5K boat. When I match the boat to my use pattern the slow speed is not a problem, but when I go where the extra knots make a difference than the faster boat is a better match. Some times a boat with a wide speed range fits my use pattern best and that is what I had in mind with Moon River happy at 7k or 18k or anything in-between. Yes there is a price to pay for that flexibility in the cost of the boat and the fuel when the speed goes up. My slow boats past and present are and were wonderful but limited in the flexibility department. I think this type of thinking is behind the increasing popularity of the faster SD trawlers. It's not all about inpatients to get there it's also about the flexibility.

Within the San Francisco estuarian geography, I'm perfectly pleased with a six-knot cruising speed, bringing most destinations within range in four to six hours. My semi-planing boating friends cruise at one to three knots faster than I. ... For instance (and regardless), last week's voyage from Vallejo to Petaluma (about 30 miles), I planned to leave a half hour before my faster compatriots. Knew I needed to make at least six knots SOG to make the four-hour advanced-notice opening for the Petaluma D Street bridge. For the first hour encountering opposing tidal currents, I needed to go at maximum cruising speed of seven knots.. My friends left 20 to 30 minutes later, and had expected them to catch up by the time I arrived the Petaluma River mouth. Nevertheless, they didn't catch up with me until soon after reaching the D Street Bridge. I arrived just five minutes before the prearranged opening.
